A few lines of dialogue are a veiled reference to the show's cancellation by the network. Mitchell's opening line is "They cancelled it? Really? I didn't even know the new season had started." Carter is speaking with Vala's father Jacek while Dr. Lee works on a problem:
Jacek: It's no wonder. I don't mind telling you, I'm a little disappointed in this facility. I was expecting more.
Carter: Well, at times, so do we. But the truth is the Stargate program just doesn't get the support it used to from the people in charge.
Jacek: Why not?
Dr. Lee (Interrupting): Eureka! One down, twelve to go!
Jacek: That's too bad. Because, after all your Stargate program has accomplished for this network of planets, I would think the decision-makers would show it the respect it deserves.
Carter (Shrugging): Yeah.
The 'Eureka' is a reference to the network's support for that program over the renewal of the Stargate SG1 Franchise.
The part of Jacek was written specifically for Fred Willard after he expressed an interest in appearing on the show.
At the end, Teal'c is at a viewing of the Vagina Monologues.
The painting on the wall behind Vala when Landry drops off the letter is a print of Wheatfield with Crows (Korenveld met kraaien) by Vincent van Gogh. The print on the other side of the room behind Landry is a reproduction of a drawing called Album Biennais No. 8185 by Charles Percier.
In the briefing near the beginning of the episode, Vala is seated next to Daniel and you can see that her shoulder patches are on the wrong shoulders.
