Rosi is definitely on board with the whole bombing the world eaters plan. He obviously doesn't have the technical skills to figure out how to make something like a bomb and it sounds like they might need multiple if the old stuff coming to light is reliable, but he's a fan of explosives, what can he say. If that means venturing to Helix or the Power Station (or both, he's got an explore token) then he'll do that.

Just, you know, usual caveat that I'm gonna be writing this stuff sooooo he'll hang out and look impressive and do what people ask him to do, mostly, unless he feels strongly about something.
