Well, at least the changes everywhere made it more easy to really get it when someone came up and said that they'd had a room appear in their house. That wasn't normal. Hell, Tony at his most amped back home with a whole night and endless tools on his hand couldn't just make entire rooms appear.
His jaw tightened when she explained what it was that had really shown up, the gravity of it all. It wasn't a good room, not in the least. It was, perhaps, the equivalent of the cave he'd been tortured in -- but worse, because Tony's bad place hadn't lasted for all that long at all.
The point she was making here -- what Nebula was offering was the chance to make something good out of something so bad. He got that, and he appreciated it. Nebula was -- better than most. Tony didn't think she was even aware of it. "You sure you don't want to just take it out back and go at it with a baseball bat?"
