The fact that one of Buffy's very few loose threads was picked up again! Five years later! Awwwwwwww yeah.
I am, of course, refering to the fact that Xander never told Buffy about Willow doing the souling spell. And that in this episode it almost - almost - came out, but Xander and Buffy were both too busy arguing to notice Willow's "I never said that!" Pure fucking genius.
And I loved the fact that Buffy even brought up having to kill Angel. I kept thinking that when Willow was going all psycho - why, when trying to talk to her, did Buffy never bring that one up?
Oh, I love continuity!
Plus - an extra musical bit! And "Come here, tiny man! You are small and toy-like!" Plus the fact that from what I could gather from the few lines of dialogue I understood sans amusing subtitles, they really were speaking either Swedish or Norwegian in those scenes (I know a bit of Norwegian, thanks to living with a girl from that delightful land for nearly a year. We used to sing Norwegian folk songs to the cat. Swear to God. But that's another story.).
Oh, I just loved it. Thank you so, so much, Kate! You're brilliant. And I shall send you sumptuous gifts in return. Also, I may ask for more episodes in the future, like the evil girl I am, because it really is more fun watching them at home with someone else (the Boy, who sends his regards and thanks) than in work on a tiny screen. But you shall reap rewards for your kindness!
