Trivia: In the final episode when Buffy, Xander, and Willow are wandering off talking about shopping, Giles turns round and says "The Earth is definitely doomed!" This is a little tribute to the end of the episode 'The Harvest' when Buffy, Xander and Willow wander off talking nonsense and Giles turns round and says a similar thing.
Trivia: Clips from the final battle with the turak'han from the episode *Chosen* are featured in the movie *Johnson Family Vacation*, although there are completely different sound effects.
Trivia: Xander was originally supposed to be the character that died in Chosen. He was suppose to die saving Dawn. Since Emma Caufield didn't want to be tied to doing any future Buffy projects the script was changed so that Anya would die. The script is the same except the parts at the end written for Anya and Xander were switched as well as the parts for Andrew and Dawn.
Chosen answer: Angel is saying that he is still jealous and Buffy recognizes that this is his way of saying he wishes that they could be together. That is why they both smile.
