Lee cocked his head, seeing that little flicker on Fred's face, but didn't press him on it. They already had on serious sort of topic at hand, that was usually about what Lee could handle, given his tendency to try to lighten everything, whenever possible.
Lee hunched his shoulder self consciously, not really sure how to broach it either, sharing a look with Fred. "Well yeah. I mean, you've probably figured out there's something going on, right? When I started up Potterwatch, I told Fred and George about it, and then told me about a group of folk working against You-Know-Who. Sort of like the D.A., but out of school. Fred's been in longer than me, but we figured you'd like a spot too, and could help out."
