The place where Kara works looks noticeably different here than it did in the episode "Blue." Then, it looked like a high-end coffee shop. In this episode, it looks more like a rustic, rural diner.
If Clark wants to find Kara and Lois, why doesn't he simply search Detroit at superspeed? The Detroit police (and thus Lionel) know where Lex was gunned down. Lex was following Kara's GPS signal when he was shot down, so he had to be close to where Kara was kept within the fence. There's no indication Finley moved the body (which certainly would have killed Lex anyway). And Kara stays at the same location for the rest of the episode. But even if Lex wasn't killed close to Kara's location, Clark has superspeed and superhearing.
Inexplicably, Clark doesn't tell Kara that she's a Kryptonian, or that she's supposed to have superpowers. Why would he keep this from her? Much less let her go and end up in the clutches of Lex, who Clark has just accused of having nefarious motives for dealing with Kara. She might be skeptical, but that seems better then letting Lex experiment on her.
It's a dramatic and directorial necessity that Clark views Lex's memories in the third person, rather than from Lex's point of view. However, when Clark sees Lex gunned down the "memory" continues after Lex has collapsed. Lex can't have a memory of something when he's unconscious.
Lionel: (about Lex) We really never had a close relationship. A lot was said. A lot went unsaid.
Clark: Speaking of heartbeats, you didn't have one for over 18 hours.
Chloe:I was hoping we could skip the lecture and go straight to the "welcome back" dinner. I'm starving.
Clark: It's 15 hours longer than the last time, Chloe. I've been sitting here, literally, trying to think about what to say at your funeral.
Chloe: Well, let's both be glad that I'm alive, 'cause I know how much you hate giving speeches.
Doctor: I watched three field officers die after their brains went into electro-neural shock. That machine is a deathtrap.
Lionel: I pay you a small fortune, doctor, so please withhold your negative opinions.
Lionel: There is something I was afraid that I would never get the chance to tell you.
Lex: Yeah? And what's that?
Lionel: I love you, Lex. My son.
Chloe: Maybe I am pushing my luck with this whole death thing. I mean, it is death, after all.
Lex: It's like a reflex. I see you and start defending myself.
Clark: That's what guilt does to a person.
Clark: There's a side of you that knows what's right.
Lex: Wow. Now what would I do without Clark Kent, voice of reason?
Clark: That voice isn't me, Lex, it's you.
Kara: See, Clark didn't even mention that you were friends. What happened?
Lex: I grew up.
Lois: What are we doing, Lex?
Lex: No one asked you to be here, Lois.
Lois: Trust me, I never planned on being your Sundance Kid, especially in the armpit of Motor City.
Finley: Hey, bald man, look, is it really worth killing her to get to me?
Lois: Rhetorical question, Lex!
The following scenes were left out of the episode:
- Finley holding Lois at gun point, because he thinks that she will take Linda (Kara) to a lab to have her studied. After some persuasion to spare Lois, Finley locks her up with Kara.
- Lois and Lex leave the diner to see Kara being driven out of the area.

Kara's bracelet has the original Superman symbol on it.
Aaron Ashmore is credited but doesn't appear.
Music: Say It Again (Marie Digby)
In-joke: An amnesiac Kara is given the name "Linda". This is a tribute to the Pre-Crisis Supergirl who was discovered by Clark while living in an orphanage going by the name "Linda Lee."
Corey Sevier (who plays Finley) is Laura Vandervoort's real life boyfriend.
Lois: Does MacGyver blush every time he walks past me?
Referencing the 1985 series starring Richard Dean Anderson as MacGyver, a troubleshooter who refused to carry a gun and possessing a gift for turning everyday objects into weapons, explosives, and tools.
Chloe: Lois, Kara, and Lex? Not exactly Three's Company.
Referencing the series starring (initially) John Ritter, Joyce DeWitt, and Suzanne Somers as roommates. Ritter's character Jack Tripper had to pretend to be gay so their nosy landlord would find the rooming arrangements were acceptable.
