Cool! I'm starting to get a bit of a shortlist for explores since Rosi also told Jason he'd have him come on one soon. Jason and Stone can both fly, big perk! Honestly I think he'd trust Stone more for an exploration just because while he's sympathetic toward Bucky and doesn't mind him, he's a little paranoid about going off into the woods with some brainwashed assassin with questionable mental stability lmao. Maybe in a group. They do need to take a boat out though!

And yeah, Rosi can teach Stone things. He'd be surprised anyone wants to learn something from him, haha. Not sure what useful things Stone wants to learn from him that would actually help with the World Eaters particularly but I'm sure they can brainstorm a bit.
