First appearance of Ian Somerhalder as Adam Knight. (edit) Music: "Future Proof" by Massive Attack, and "So Far Away" by Staind. (edit) Last appearances (presumably) of Lorena Gale as Dr. Claire Foster and Jesse Metcalfe as Van McNulty. This is the second "reversal" for the Foster character - in the comic books she's good rather then evil/immoral, and despite what happens here, in the comics she is a part of the adult Superman's life. (edit) One of the headlines on a newspaper on Ian's cart mentions a "Themyscrian Queen Addre... ... tican" - an in-joke reference to Wonder Woman of DC Comics. Presumably it should say "Addresses the Vatican" or some such. It's also presumably a deliberate in-joke as we hopefully won't be seeing Wonder Woman or hearing of a mythical super-powered Amazon meeting with the Pope at the Vatican. (edit)

Ian: Do you feel any different?
Eric: (throws Clark across the room) Does that answer your question? Welcome back to being normal, Clark. Kinda sucks, doesn't it? (edit) Adam: Would you believe me if I told you I was a nice guy once, with no issues?
Lana: Nice guys normally have the most issues. (edit) Lionel: It's sad to see a man who's lost his mind. But it's tragic when he's convinced himself that he's sane. (edit) Ian: I know I've made some mistakes in the past ... but I'm better now.
Lex: And I'm happy for you ... both of you. Now take your little cart and go sucker someone else with a bank account. (edit) Asylum Attendant: (to Clark) Jeez, kid, you seem to know a lot of people in here. (edit)

When the guards caught Lex trying to leave to help Clark, they gave him a shot in the neck. He was moving around quite a bit and so was the needle that was in his neck. A needle that far into the neck would cause considerable damage if moved like that. (edit) When Clark rips the fence open, it is easy to see the weaving of "fake fence" down the line he rips. (edit) The guards at the asylum use a tazer gun to stop Lex as he attempted to escape. In the next shot of Lex on the ground, the wires that were connected to the gun that tazed him have disappeared. (edit) At 26:30 while Lex is getting hit, there is a black object stuck to the camera in the upper right of the shot. It is visible several times until 27:15. (edit) Near the beginning of the episode, Lex says "I know your secret", but when Lionel is playing it back at the end of the episode, he says "I know your secret, Clark". (edit)

Road Runner
When Lex starts his painting in the day room, other inmates are watching a Road Runner cartoon in the background. Road Runner is a Loony Tune, which is produced by Warner Studios...which also runs DC Comics. (edit) Orderly: Get up, Curly.
The orderly, when speaking to Lex, is of course talking about another famous bald guy, Curly of The Three Stooges. (edit) Ian: If it isn't Klu Klux Van
The Klu Klux Klan has historically been a racist group targetting minorities. Van has a prejudice against meteor freaks. (edit) Adam: "The Midwich Cuckoos"
The book Adam is reading in his hospital bed is "The Midwich Cuckoos" by John Wyndham, which was later adapted into the movie Village of the Damned. The John Carpenter remake was one of the last movies Christopher Reeves (Superman, Dr. Swann) starred in before his accident. (edit)
