Oh yeah, I definitely see Rebekah and Molly having contact, then. And Molly's a pretty patient person so I hope things will go well and there will be some female bonding too. And I get the feeling Molly will search out British people when she gets homesick, so she may look for the others, too.
Oh, Kirk will definitely get along with them all, I think. In my head, he's consumed all things nerdy and so anyone who's canon-punctured, he'll probably know all about them (being from the future) and just be like "YOU ARE AWESOME!!!" But yeah. He will totally love making new friends. He'll be missing his crew that isn't there and will want to distract himself, so new friends will be a thing.
