In this episode we find out that Abby was born at 8:03pm on January 10, 1969.
Abby drinks alcohol for the first time since getting sober in 1995.
Goof: When Greene searches Rachel's backpack and finds the pack of Marlboro cigarettes, the cigarettes are shown tobacco-end up. This is odd, as all filter cigarettes are packaged with the filter end up.
Frank: Is this great or what? Empty chairs. Empty racks. Nothing like sub-Arctic temperatures to keep the freaks at home.
Randi: Abby, what's your sign?
Abby: ...out of order.
(Abby walked in on Carter and Susan kissing)
Carter: I'm sorry about that.
Carter: I should've said something to you sooner. It just sorta snuck up on me.
Abby: Hate it when that happens.
Carter: Yeah.... It's really more about friendship than anything else.
Abby: Really? Never seen you kiss Frank like that.
Abby: I haven't seen you around lately.
Luka: I've been working nights.
Abby: How's your Christmas?
Luka: Quiet. What'd you do for New Years?
Abby: I worked.
Luka: That's always fun.
Abby: Did you make any resolutions?
Luka: Uhm... Help out more.
Abby: Help out more where? Here?
Luka: Uh, no. Europe. I've volunteered to go to Bosnia for two months with Doctors Without Borders.
Luka: Yeah. I speak the language.
Abby: What brought this on?
Luka: I don't know. Change of scenery?
Frank: (to Abby) If I find his mom, can I have those hockey tickets you pinched off that stiff?
Greene: Why is the thermostat in the lounge set at 56?
Frank: Get used to it, we are heading into another ice age. That's what killed the dinosaurs.
Greene: Ice age didn't kill the dinosaurs, it was cholesterol.
Carter: I got stabbed! I got stabbed in the back! Where the hell were you? You were the same place you've been my entire life, you were someplace else!
This is the first episode of the series to not feature any "and" credit regular cast in the opening theme.
Music: "Battleflag," Lo Fidelity Allstars (also used when Carter is attacked by Sobriki as he finds a wounded Lucy in the Season 6 episode "Be Still My Heart.")
Although in the opening credits, Paul McCrane does not appear in this episode.
