Preexisting CR or not, I think A2 / Anna here might get along well with Sara. Anna hangs out in crappy bars and gets drunk as a totally healthy way to cope with a bunch of bad emotions, especially over the course of the past year, most of which wasn't spent on the app. She's also got a history of starting fights when she was younger and might have stuff in common about having to suddenly reroute her life plans? (Even if they don't actually talk about it; Anna'd much rather have a drinking buddy than somebody to talk about the past with.)
