Frigga misses them all deeply and constantly. Yet, she is still herself, so she manages. Also she believes, of all her family, she is best suited to being stuck in Darrow, either for their sakes or the sake of everyone else living here. She also mothers anyone who gives her the opportunity and seems like they could use it. The only things I'd change are she should be making and developing more relationships with people, and something Brad and I are working on would already be done, but there are only so many RP hours in the day and I can't completely bend my will to the Queen of Asgard.

Between the growly cowboy lawyer with enhanced strength, telekinesis, and transmutation and the covert operative who's trained in exfil, one or the other of them would manage a way out of any normal (for them) sort of locks. If the locks are such they can't get out on their own, they'll keep working on it and other plans for escape. There might be a bit of snark while they did, though. Otherwise, they'd mostly ignore each other and once out, go their separate ways.
