Betsy will want to keep an eye on Pixie so probably getting a Butterfly Convo now and then.
Emma will be out there trying to find Pan's Shadow with magic, so that'll be fun. Lots of light around him, so if Alina wants to help out that might get rid of him??
Caroline, you may have to watch Buffy, she'll be super eager to fight things. That hellmouth spawn is going down, and then she's going right on to something else.
Natasha is going to be after the Chitauri with everything she's got, which is Widows bite and guns, of course.
Betsy is psi-knifing and other things whatever crosses her path.
Anyone need electronic things disrupted? Kitty will phase through it. Just not the sentinel cause that's definitely programmed against her. Anything else, robots etc, she's on it. But she's still going to punch the shit out of that sentinel.
Liv will go zombie mode and help where needed. She can't really be hurt so long as they don't shoot her in the head. :X
Trish will fight where and when she can, but she's not super and she knows it.
ANYA IS NOT KILLING THINGS, but webbing the crap out of them. :D
Clara has no weapons so she's protecting the children.
ARROWS ARE KATE BISHOP'S BEST FRIEND. And so is Sam Winchester and America and Billy, so she'll close to them.
Syd is totally not a fighter, she's staying in the caves.
