Daisy - Jemma will definitely fuss before she leaves. Makes sure she has plenty of medical supplies etc. Yes she knows she can handle herself, but she still worries. Jaina and Kaidan as my two tech people will just wish her luck.
Clarke - I have a bunch of people that can be friends with her, I'm happy to just throw people together and see what sticks.
Jill - Obviously both Adrian and Mason adore her. Eliot is always happy to be a fashion guinea pig. And Ignis likes well-tailored clothes. And Rashel would be interested in clothes that change with her, like Keller. Since, she can change now. Also, I think she'd get on with Kara. Then again, who doesn't?
Quentin - Obviously El adores him to pieces. And, he works with Neria who finds The Magicians incredibly useful. And, obv briefly dated Julia when you had her here. Ignis could also be an interesting friend for him, because he seems very proper, but is actually a complete nerd, especially when it comes to things like magic. And, I think he'd get on well with Kara.
Rey - Obviously she still has Poe, who is always happy to spend time with her. So is Jaina who loves her to pieces. Ignis has been enjoying getting to know her, and while isn't ready for anything romantic, is definitely interested in becoming friends. Obi-Wan is also always will to chat etc.
Rose - Mason is trying very hard to not tell her about any of her future kids from Atlantis or Breck etc. He's tempted though. Otherwise, I think a large majority of mine are friends with Rose already.
Sam - So, when Dean discovered Mari was in medical, and that Nat knew and didn't tell him. He punched the wall, since he couldn't punch a specific person. Which is how he broke his hand, and why he's bitching. Because it's self inflicted and he knows it. And also why Natasha is hovering. Otherwise, I think he'd get on well with Ignis. They both have a love of research, planning and have ended up hunting monsters out of necessity etc. Hawke is quite like Dean in terms of personality, while also looking like Jess. So, I'd think they'd get on, once he got passed her looking like his dead fiancee.
