Re: Peyton, Mac and Hawkes for sure knew her quite a long time according to spoilers, so I'm guessing that possibly Stella had met her before she came to the lab too, although she didn't know her as well as the 2 guys. As for Flack acting like she was an old bud, well he's a cop, so he technically could have had an opportunity to meet her a few times through the years, in seminars or whatnot. Either that, or he was just being flirty with a pretty woman who he doesn't realize is doing his Boss... :lol:
