Even though I like both Willow and Oz more then Xander and Cordy individually, the latter still makes the #1 spot of my all time favorite Buffy-verse couple,
Also two of my favorite lines are in this episode.
1. Cordelia: I bet you wouldn't. I bet you'd let a girl go off to her doom all by herself.
Xander: Not just any girl. You're special.
2. Xander: Hey, Angel's our friend!... except that I don't like him.
