I can just imagine Jay bonding with Steph and Babs (as friends) and it being a point of awkwardness between him and his "brothers." I love the idea of Jay and Cass bonding as well, but could just not see any romantic feelings there. I also see Scarlet transferring her 'Papa' over to Jason.
I think he would just get along better with women. There'd be no testosterone/measuring stick/masochistic jostling, etc., plus he just seems to get along better with women than men.
