Episode 1 (deleted scene):
ROSLIN: What's in the package?
BILLY: Uh, it's a gift... from a captain of one of the ships. Uh, there's a note, "Please accept this on behalf of the people of Aerilon. It was taken on the capital of our colony during the attack."
ROSLIN: (opening package, looking at 8-sided framed photo) "Oh." (caption reads: "Lest we forget", queue creepy music.)
I have stated before that I believe this photo hanging over Roslin's desk is either
the Palladium or
the Oracle (at Delphi) in Greek mythology.
Episode 8:
BALTAR: Now, we just pop this in the slot and wait for the result. Green, you're a normal human being. Red, you're an evil Cylon. Should take a couple of minutes. So, uh, tell me, are you from Aerilon? Slight trace of an accent there...
BOOMER: What?
(Looks profoundly disturbed.) Uh, no. Troy. Troy.
BALTAR: Troy... tell me, why is that familiar?
BOOMER: Mining settlement? The accident.
BALTAR: The explosion, right. That was tragic. Your family...
BOOMER: Died with the rest.
BALTAR: I'm very sorry.
SIX: It's a lie.
