Ferr Aesir

Behemoth was a lot kinder when she first started out, so I think she would have apologized to Feyie as well for knocking her son around. It would have been a funny sight for sure! And Ferr asking her out, she would have rejected him then and there, yeah. Wouldn't have been brutal about it, mind you. Feyie might have sense something awkward between Ferr and Behemoth for a while after that, but Behemoth wouldn't have said anything to her. It would be a nice, silly memory for Ferr and Behemoth now though, so I'm all for it being canon!

She'd be down for catching up every now and then, since I feel Ferr is one of the few people Behemoth considers a friend due to how long they've known each other. She would invite him to Era as well, or they could even coordinate days off to go outside the city for a bit to forget about things? Ferr can try and convince her to sign up for a captain's spot. Definitely seems like something he'd do, but Behemoth would calmly refuse every time. Ultimately she doesn't think Eos is worth dying for, but she'd never tell Ferr that, and would avoid the topic vehemently.

If they were working together and encountered a Grimm Troupe member who gave them a fight, would Ferr want to kill them or take them into custody? Behemoth would opt for the latter, but knowing how Feyie died she'd leave the decision to Ferr.
