SPOILERS: S7 - Post-Chosen
CHALLENGE: photo album/snapshot
"What about your father? Surely he kept a few?"
"You're right." Buffy gives him a smile that's nine parts brick and mortar to hide behind and one part genuine warmth. "I'll ask him."
That's when Angel brings out his dented and battered strongbox and hands her the photo: Spike in a wheelchair, looking brassed off but unbroken, giving the photographer his two-fingered salute. Angelus took the picture. Angel kept it.
Buffy never asks what else Angel is keeping inside that box. She just takes the photo and carefully puts it away.
