Sara is still one of the few people that can startle a laugh out of Oliver. Perhaps because she knows him so well, or more likely because he can let down his guard when he's around her.

He doesn't regret his decision for an instant because this is what he needs right now. He needs warmth and he needs light and Sara has always been both.

As she melts back into the crowd to pick up whatever death-concoction she's going to come up with that will bring a pounding headache come dawn, Oliver goes to retrieve her knives and smile to himself. He trusts her. Whether it's with drinks, knives, or the history that she can't quite bring herself to share with him yet.

He'll always trust her.
