At the beginning of the episode, Selfie Guy accidentally falls off a cliff. Instead of splattering to the ground far below, he becomes suspended ten feet off the ground, caught in some sort of anti-grav field.
At the end of the episode, a couple of snowmobilers the long-dead body of Selfie Guy, who's been floating in place for four months. It's a gruesome discovery, as his body's all withered and decayed.
I dunno... I get that the producers wanted to show he'd been stuck there for a long time, but would his body really deteriorate that much in a frigid environment like this? Wouldn't it be perfectly preserved, like it'd been kept in a freezer?
Also, this episode also gives us another flashback of Harry's ship crash landing in the mountains. If you look closely, you can see a lightning strike knock one of the glowing rings off the side of the ship and send it flying.
In the final shot of the episode, we see the snow on the mountain's melted a bit, revealing that Selfie Guy (along with two hawks or eagles) are suspended above a large metallic disk.
Is this disk the same one we saw get blasted off the spaceship? It would make sense. This disk obviously has anti-gravity properties— something that would come in handy on an interplanetary craft.
It's pretty obvious this is the component Harry's looking for, that will help him repair his ship, complete his mission and return home.
• As regular readers of my reviews (both of you!) know, I like to try and figure out where various series film their location shots. Most of the Arrowverse shows are filmed in Vancouver, so it's fairly easy to find the buildings and streets they regularly use.
Despite the fact that Resident Alien takes place in the fictional town of Patience, Colorado, it's filmed in Vancouver as well. The interiors are all filmed on a soundstage there, while the exteriors are shot in the tiny town of Ladysmith. It's located on in British Columbia on Vancouver Island, which is about twenty miles from the city of Vancouver.
Since Ladysmith's such a small town, it's pretty simple to scope out the locations they use.
Near the beginning of the episode, we see Max run screaming out of the clinic— where he's just encountered Harry again— and race down the street in terror.
Here's the real life location of the clinic. You can identify it by the three distinctive protrusions above the windows in front, as well as the large sign on the side. In reality the building's a mundane old credit union a block or so from Ladysmith's business district!
Oddly enough, the clinic seen in Pilot is a completely different building from the one in this episode! I can think of two reasons for this: A: the producers changed their minds and went with a location that looked less like a grocery store, or B: the owners of the first building decided a filming crew was causing too much of a disturbance and told 'em to get lost.
Max runs down the street from Harry and hides under a bench, as his embarrassed parents attempt to coax him out.
This area's located on 1st Avenue, which is Ladysmith's main street. Note that it looks like the producers added Max's hidin' bench in front of the building with the striped awnings.
Next up is what I guess you'd call City Hall, which houses the Mayor's office as well as the Sheriff's station. It's the tall brown building near the center of frame.
This building's also located on 1st Avenue (as most businesses in Ladysmith are!).
Note that this location causes a bit of a continuity error. As seen above, when Max ran out of the clinic, he hid under a bench in front of a building with striped awnings. This location is clearly just a hundred feet or so down the street from the City Hall. The clinic's nowhere in sight!
I suppose it's possible that Max was so terrified he ran several blocks before stopping and hiding under the bench. More likely though, the producers just filmed his scene while the crew was already set up on the street and hoped the audience wouldn't notice. But we did notice, guys. We noticed.
Harry exits the diner and walks up an inclined street, where he spots dozens of wanted posters featuring his alien face.
It took a while, but I managed to track down the street in question. You can see the angled road, the distinctive white railing and even the utility pole that Max plastered with posters. There's just one thing missing— the diner in the background!
As you can see, Google Maps hasn't updated this particular street view since 2012, so it's entirely possible the diner was built sometime after that . On the other hand, I can't find any evidence of a Joe's Diner anywhere in Ladysmith, BC.
I'm betting there isn't a diner there, and the one we see in this episode has been CGIed into the background behind Harry.
Just in case you doubt my claim that Resident Alien is filmed in Ladysmith, BC, I offer this scene as proof. At one point Asta peddles her bike past the LADYSMITH TRADING CO. LTD.! How's that for evidence?
Once again, like pretty much every business in town, the Trading Co.'s located on 1st Street.
Lastly there's Harry's lakeside cabin. According to the producers it's not an actual house, but a façade built just for the show, located in Howe Sound at Britannia Beach in British Columbia.
• OK, this is some hardcore nitpicking, but whatever. At the clinic, Harry enters and Asta introduces him to Judy, who's there for a routine pelvic exam. Asta then excuses herself and leaves the room.
Yeah, I don't think so. There's no way in hell a nurse would ever leave a female patient in a vulnerable position like that alone with a male doctor. Not in our current highly litigious society. That's a sexual harassment lawsuit just waiting to happen.

• Hands down the best and funniest part of this episode was the scene in which Harry attempts to improve his bedside manor and reassure a worried woman who's come into the clinic:
Asta: "She just found a lump in her breast. Why don’t you try to be a little more calming this time?"
Harry: (annoyed at her condescension) "I know what I’m doing."
(Harry enters the exam room and speaks with the patient.)
Harry: "I see you found a lump in your breast."
Worried Woman: "Yes."
Harry: "I’m glad that you came in and that you’ve been so diligent with your health. As you know, self‐examination along with appropriate screenings can greatly increase your odds of early detection, so I don’t want you to worry. Many women find lumps in their breasts all the time, and most of them are nothing, okay?"
Worried Woman: "Okay."
Harry: "Good. Now let’s get a look at that tit."
HAW! I laughed so hard at that last line I actually got choked.
• Nice Attention To Detail: When Max accuses Harry of being an alien, Deputy Baker uses her police sketch artist skills to draw his otherworldly form. Later in the episode, Harry finds dozens of wanted posters— featuring his alien mug— plastered all over town by Max.
Note that Max's writing skills haven't quite matured, as his poster reads, "havE U seen this alein?" He also advises people to call him before 7pm on weeknights, which is no doubt when he probably goes to bed. Well done, Resident Alien Props Department!
• Setup & Payoff Alert: When Harry calls Max at home, we see he's reading a conspiracy theory website detailing how tin foil hats protect against alien mind control.
At the end of the episode, we see Max took the advice to heart, as he's indeed sleeping in a tin foil hat!
• Harry calls Max and tries to convince him that the alien he's looking for has left town. When Max asks if he's sure it was THE alien, Harry says, "Yes, he was very handsome, like a young Jerry Orbach." Naturally a youngster like Max has no idea who that is. Ha!
Last week in Pilot we saw that Harry learned to speak English by watching endless reruns of Law & Order, so it makes perfect sense that he'd imprint on Orbach.
• After Harry's phone call ruse fails to work, he begins fantasizing about various ways of killing Max. Note the running joke in each of his scenarios, as Max's sneaker always falls to the ground a second after he's killed.
I'm betting the two of them will continue their Coyote vs. Roadrunner adversarial relationship all season, as Harry keeps trying to murder Max in order to shut him up and keep his secret. Having an adult alien constantly being outsmarted by a kid is comedy gold, and Alan Tudyk and young Judah Prehn are great together.
By the way, I read the first three volumes of the Resident Alien comic, and Max isn't in any of them— he's a completely new character made up just for the series.
• D'Arcy makes a date with Harry and insists he take her bowling. Strangely enough, he's never heard of the game and has no idea what she's talking about.
This is odd, as earlier in the episode we see Harry's quite adept at using the internet. He even fakes being a doctor by easily looking up numerous medical procedures on his phone. So why doesn't he just google "bowling?"
Later on we find out the thought apparently never occurred to him, as he's still ignorant of the game and how it's played when he shows up at the alley.
To make it even stranger, at the end of the episode he senses that Asta's feeling sad and offers to play cards with her. So he understands the concept of games and other recreational activities. And he doesn't seem confused by the cards when she deals them out to him, implying he's familiar with whatever game they're playing.
Apparently the producers needed to fill this episode with some more "Stranger In A Strange Land" humor, and came up with Harry's bowling confusion, despite the fact that it makes no sense.

• At one point Asta tries to get sullen teen intern Jay to open up to her and express her feelings about the death of Dr. Hodges. Of course Jay's horrified by Asta's amateurish attempts at psychotherapy and hurries off.
I'm still standing by my theory that Jay will turn out to be the baby that Asta was forced to put up for adoption when she was sixteen. Why else would they have included her character?
• Ben has a therapy session with Harry, who he believes has clinical psychology training. Harry couldn't care less about Ben's blatherings though, as he spends their time doodling various idea for killing Max.
I'm intrigued by Harry's drawings, as they look exactly like something a human would sketch. One would think an alien mind would render concepts that are completely incomprehensible to Earthlings. Did taking on human form affect the way Harry draws?
• I gotta say, the last thing I expected to see on this show was an adult alien physically torturing a child in order to assert his dominance over him! You're weird, Siffy Channel!
• Near the end of the episode we see a montage of the various townspeople relaxing after hours. Deputy Baker spends her evening in front of the tube, and has clearly developed a crush on TV celebrity Giorgio A. Tsoukalos.

In addition to being the subject of a popular meme, Tsoukalos is a ufo-logist, who subscribes to the theory that aliens interacted with ancient man and helped us build monuments like the pyramids and Stonehenge (something that's actually touched on earlier in this episode).
I think I see where this is going. Due to her infatuation with Tsoukalos, Deputy Baker will end up being the first adult to believe Harry's an alien.
• Harry finds a deposit of tellurium in the local mine, and uses it to cobble together a small anti-grav disk.
Oddly enough, tellurium is a real substance! It's a rare, silver-white metal that's related to selenium and sulfur. It's sometimes used as in semiconductors, which makes its use here all the more plausible.
Gosh, if only Harry would share his formula with us, we could have anti-gravity technology right now!
• This Week's Best Lines:
Harry: (voiceover) "All beings of the universe are different. For instance, my people are brilliant. Humans, on the other hand, are so dumb that they think the leading cause of death is heart disease. It’s not. It’s almond milk. Even the Grey aliens won’t touch the stuff."
Max: "Sheriff, I’d like to file a murder complaint. I know who killed Sam Hodges."
Ben: "What are you talking about?"
Sheriff: "Is that so? All right."
Ben: "Sure, have a seat."
Sheriff: "Go ahead and lay it on me, little deputy."
Max: "It’s the new doctor. He’s an alien."
Ben: "Okay, on that note, I’m gonna need everyone out. Kid’s a little delusional with a fever. Maybe no talking for a day."
Sheriff: "Wait, wait, wait, wait. An alien? What you mean? Like, he ain’t got a green card or something?"
Max: "No, like, alien alien from outer space."
Sheriff: "Outer sp..."
Ben: "And shoot me."
Sheriff: "What the hell are you teaching this kid, huh? You know I could lock you up for lying to an officer of the law? That is a crime. You’re committing crime."
Ben: "Got a sick kid, okay? Gonna need everyone out. Got a sick kid. Just..."
Sheriff: "Yeah, he’s sick all right. (to Max) Let me ask you something. You got HBO in your house? Here’s what I want you to do. I want you to watch Oz Season One, and then come back and tell me if you want to go to prison!"
(Harry nervously gives his first ever pelvic exam to Judy.)
Harry: :Okay, I see your problem. You sat on an earring."
(He tries to pull if out.)
Judy: "No! That…"
Harry: "Sorry."
Judy: "That’s supposed to be there."
Harry: (thinking about Max) "This kid is a menace. He just won't give up. Where was that effort from the humans when we were helping them build Stonehenge? A bunch of idiots just sitting around drinking mead, making us do all the work. Lazy druids."
(Harry tries to fool Max into thinking he's gone, by pretending to be a friend from school.)
Harry: (in a high-pitched voice) "Hi, is Max there?"
Kate: "Who’s this?"
Harry: "I’m a friend of his from school. My name is…Elvis."
Kate: "Yeah, okay. (handing the phone to Max) "Max, friend from school."
Max: "Hello?"
Harry: "Hi. I saw your poster on the street."
Max: "Yeah?"
Harry: "And I saw that alien on a bus leaving town, so you don’t have to worry about him anymore."
Max: "Are you sure it was him?"
Harry: "Yes, he was very handsome, like a young Jerry Orbach."
Max: "Who? Wait a minute, I don’t know you from school."
Harry: "You’re right. I’m a post office man. I’m good with my eyes, and I saw that alien, and he’s gone."
Max: "If you’re a man, why do you have a kid’s voice?"
Harry: "Tricycle accident."
Max: "Uh‐huh. If you work at the post office, how much does a stamp cost?"
Harry: "One hundred dollars."
Max: "I knew it! You’re him!"
Harry: "One thousand dollars!"
Max: "I know it’s you, and guess what, alien, you can’t kill me. My parents know you’re after me, and if I die, they’ll know you did it, and you’re dumb. Stamps are like thirty bucks each, stupid."
Harry: "Don’t call me stupid… you little shit."
Max: (gasps) "S‐H‐I‐T is a bad word, stupid."
(Max hangs up.)
Harry: "That’s it. I’m going to kill him."
(Harry stares at Asta, Sheriff Mike and Deputy Baker as they argue.)
Harry: "I can read the emotions on their faces. (looking at Asta) Sadness masking as anger. (Looking at Sheriff Mike) Weakness masking as superiority. (Looking at Deputy Baker) This one’s like a pet rabbit that you yell at so much its hair starts to fall out."
(Harry goes bowling with D'Arcy, and runs into Judy.)
Judy: "So we meet again."
Harry: "Do I know you?"
Judy: "Yeah, you had your hand inside me the other day."
D'Arcy: "Uh, narrow it down, Judy."
(Harry runs into Sheriff Mike, who's there with his league at the bowling alley.)
Sheriff: "Well, well, well, look who came into my house."
Harry: "You live here?"
