Faith just glared at Buffy. She was the one who went away? She was the one begging to be let in and realizing she was never going to outdo Angel. He was always gonna belong to Buffy and vice versa. She was too wrapped up in it and couldn't break free. Faith was looking for solid ground and Buffy hadn't given it to her.
So she'd lied and she'd murdered and she'd hurt people. It wasn't justified, she knew it and most days she didn't think Buffy would ever forgive her. Faith just couldn't let go of the anger surrounding Buffy's refusal to give up on Angel. To move on.
"You're trying to tell me it didn't have anything to do with Angel. Or with Spike, when I came back to help you with your First Evil problem?" Faith's voice had lost all of the bitterness. She didn't know why. She was just tired of fighting all of a sudden. All of a sudden, she wanted to go home.
