Anya refers to Andrew as "what's-his-face, the other guy." This is part of the running joke of the Scooby Gang being unable to recall Andrew's name, also present in Gone (2002), Never Leave Me (2002), Grave (2002) and the comics Turbulence, and Own It, Part Five.
Nicholas Brendon does the opening narration "This is what happened this year" which precedes a longer-than-usual recap of all the major events of season six.
Buffy states that killing someone changes you, followed by "Believe me, I know." She has twice thought she had killed a person: the robotic Ted in Ted (1997) and, more recently, when she was framed for the death of Katrina in Dead Things (2002). This also reflects her experience with Faith when the Slayer went rogue after accidentally killing Allan Finch in Bad Girls (1999).
The title of the episode is a reference to the previous one, which ends with Willow saying "One down" after killing Warren. It is also a double entendre as to there being two episodes left in the season (this one and Grave (2002)).
This line was cut due to length:
- Clem: "We don't have a plan. Don't we at least need a plan?"
- Dawn: "Buffy and her friends never have a plan. They just sort of... jump in and don't know what they're doing."
- Clem: "And this works?"
- Dawn: "They never really let me come along. Guess we'll find out... It's okay. I mean they usually come back in one piece."
