Angel's reaction stopped Buffy in her tracks. She had been ready for a fight. She had been ready to argue her way in or pull Dawn out completely, but this? This was too easy. He left her there blinking at him with her mouth slightly open as she tried to compose herself.
"Well, good," she said finally, still looking and sounding surprised. She was very close to bringing up their past and why it would be horrible for them to work together, how it could bring up old feelings, how it could complicate things, but Angel seemed content to ignore it so Buffy was too.
"I'm glad that's settled them," and with that she fell into an awkward silence. Seriously. She could probably cut the awkwardness that hung in the air with a knife.
