Chloe - is in the same year as Peadar, but she's probably otherwise out of Morgan's scope. And she'd absolutely be intimidated by her if they met.
Fabian - knows her through the Order, plus he's friends with Alice, so he might have know her before that. He thinks she's very cool, and like Gid, he overlapped with her brother Madog and her nephew Peadar.
Malcolm - would know her through St. Mungo's as well as through both Nick and Angus. He's fairly strait-laced, but he has crazy friends, so they should get along IF she's willing to put up with his workaholism and current flakiness.
Claude - is friends with Angus so will probably know her. Might not entirely approve of her, but
Peter - knows her through the Order and thinks she's a bit scary. She's probably also patched him up more than once.
