I am obviously not excited for either of these at all!
Jemma and Caitlin are basically MCU/DC mirrors so I am 100% sure they will get along and Caitlin will absolutely adore having someone to bounce wildly crazy ideas off of once she trusts Jemma - which since she lives with Daisy and works with Barry that's likely to be quickish. I don't have anyone directly in science, but obviously there's some cross over between science/innovations and technology so she'll likely get to meet Jim that way and also cause he spends too much time with Daisy for definitely no reason at fucking all. I kinda apologize for Bellamy cause he will probably find her a Bit Too Cheerful in many ways, but he respects Daisy so he'll grow to like her in his own ridiculous way. Clarke and Lexa are also obviously around periodically cause of Bellamy and she'll work adjacentish to Clarke since Jemma will definitely get pulled in on medical stuff as needed - so she will definitely get to meet Lexa who I suspect will really enjoy her enthusiasm as Lexa likes that sort of thing.
Ellana is going to fucking love not being the only elf and she is going to abuse the fuck out of Neria knowing Baby!Cullen and will in no way whatsoever admit to having boned an elven deity and that is utterly beyond any reasonable point and how dare anyone even think that happened cause it DEFINITELY didn't and she denies it and everyone is just delusional. I don't have anyone in magic right now - but Margo helps out and is obviously besties with Julia so she's around and Thea, Caitlin, and Lucy are all very close with Mordecai (honestly... most of mine are but those are the ones with a possibility of showing up at his work rofl) and he works there part time when not doing board stuff and is helping Julia with the two current projects (fixing Ellana's hand and Thea's whole like death wish thing) and so basically Neria will have loads of connections with mine rofl.
Like I said, clearly not excited and definitely, obviously have like zero plot potential with these two, wow.
