Nyx and Alistair are both kind of pushed out of their situations, so they're open for interactions unless I make Nyx storm after Gellert and be all offended that he blew her off, but that's not in her character. She give him a grandiose finger to the back and go on her "merry" way, but Alistair would be.... gullible in a sense that he's a curious little monkey that would do something stupid because its fun.
I'm debating on Corra just like making an explosion for the fun of it, but I don't know how useful it would be other than to start a forest fire XD
Shertul would certainly appreciate an explosion right now, and that would trigger the fight they're all trying so hard to avoid xD
