Buffy the Vampire Slayer, Season 7

Xander:
I've been through more battles with Buffy than you all can ever imagine. She's stopped everything that's ever come up against her. [Buffy and Faith walk in] She's laid down her life -- literally -- to protect the people around her. This girl has died two times, and she's still standing. You're scared? That's smart. You got questions? You should. But you doubt her motives, you think Buffy's all about the kill, then you take the little bus to battle... I've seen her heart, and this time, not literally. And I'm telling you, right now, she cares more about your lives than you will ever know. You gotta trust her. She's earned it.

Faith:
Damn. I never knew you were that cool.

Buffy:
Well, you always were a little slow.
