Buffy knows her romantic entanglements have been missing something, but hasn't yet put that knowledge into practice. Following an accidental engagement, she takes the first step, by secretly making friends with an enemy.
One decision can change so much. Instead of telling Buffy that Spike is in love with her during Crush, Dawn tells her about a list. It leaves Buffy thinking about all of the ways that Spike could have used to kill them… but didn’t.
