Plz to be sticking Jono with someone he doesn't normally interact with?
...or, if Doc's okay with it, Wisdom.

Because there's really nobody else in the mansion (now that Sage is an NPC) that Jono really truly dislikes beyond his usual base reaction of irritation/contempt.
Doc, let me know.
Jono's going to be in his room most of the day, playing guitar and writing music, still trying to sort of get over the fact that Ange and Paige bailed on him.
If you want him, you'll have to brave the cave.
Pyro is ... probably not going to be helping Mystique

He'll be alone and pouty at the Brohood house, sulking because he can't burn things. Big things. There might be fires in town...
