Tony followed dutifully (of course he did) his nanobot housing in his back pocket because the reactor had come and stolen back the spot where it used to sit so -- he was going to have to do some work on that front some time soon, he figured. But now was for this.
He paused at the threshold to Nebula's actual bedroom, curious about the noise for a moment before moving on because he had to. And because the sound of engines didn't really do it for him. Maybe some day he could go into space for a reason that wasn't for work. Maybe then he'd change his mind.
"Well," he said, looking at the room once it was opened up -- and he didn't miss Nebula's discomfort. "That's the worst, isn't it." He settled a hand on her forearm, comforting before nodding. "I'll take care of it. And then I'll even help you seal it off. I'm gonna look around for a bit, see what kind of tools I need for the job. You don't have to stay."
