When Cole Barker is shot for the first time in the party, Sarah says "oh my god, you're shot." She pronounces the word shot in an Australian accent. This is Yvonne Strahovski's real Australian accent.
The t-shirt Sarah is wearing as a pajama top is the same shirt Chuck wore under his white dinner jacket at the end of Chuck Versus the Seduction (2008).

Robert Picardo as Dr Howard Busgang makes a reference to a paper called EM-ONE when talking with Sarah and Casey. On Star Trek: Voyager (1995), his character was called the EMH, or Emergency Medical Hologram Mark One. The paper Busgang refers to was written by "Singh," also a Star Trek reference.
Robert Picardo (Perseus) starred alongside Robert Duncan McNiell (supervising producer) in Star Trek: Voyager (1995).
