While Buffy is playing charades with the crowd at Xander and Anya's wedding, she puts her fingers up to her head like horns and you can hear someone in the background guess "Deathwok Clan!". This is a reference to Lorne from Angel
, who is a demon with horns and a member of the Deathwok clan. See more
Okay. For the last time. I, Anya, want to marry you, Xander, because I love you and I'll always love you. And before I knew you, I was like a completely different person. Not even a person, really. And I had seen what love could do to people, and it was hurt and sadness. Alone was better. And then, suddenly there was you, and... you knew me. You saw me, and it was this... thing. You make me feel safe and warm. So, I get it now. I finally get love, Xander. I really do.
