"He knows about what we did." Fred had filled him in on a good bit of what her life had been like while she told him about Cordy. She couldn't leave things out. It was hard to answer "How'd you meet?" without bringing up demons and queens and different dimensions. Well, it wasn't hard for normal people; Fred didn't see any reason to hide it from Sam.
"I was about to head out to do some work. You can come along if you'd like? I bet Sam has some hero-y stuff to do." She didn't know if he did, but that seemed like a Sam thing to her. She gave him a soft hip check and a smile.
"Plus, we can talk." They hadn't had much chance to talk, getting Cordelia settled in and all that.
