reaches for ur girl!!! There's a lot of nifty little stuff I think would be fun, and a lot of this could be handwaved if you wanna, but! Peter and Jinx hanging out after that text convo, Jinx showing Peter some different weapons / dummy target practice, Peter showing Jinx how to play some instruments.... He also just found out from Wrench about Jinx's death so he's definitely going to be Worried about her!

Also I'd love to get Paimon @ her again sometime, he'd be wanting to check on Jinx himself and he could potentially help her out a little bit with some things if you like. One of his abilities is dream/nightmare manipulation, so he could help take away her bad dreams one night or give her some good ones, or just generally help a bit with her mental state by giving her some demonic support. (In exchange for an offering, but it's totally fine to make exchanges with demons!!!) Or, she could just get some wishes granted from him, she deserves to be spoiled okay and he really likes Jinx
