It hadn't occurred to Tony that Hammer had, so far, been politely adhering to reasonable business hours in their sordid exchanges. Nothing Tony ended up doing ever felt like reasonable business, after all, and most everything had started to blend together within the first few weeks. If he was sleeping at night and functioning during the daylight, it was a fluke and certainly involved a higher (earned or not) power because 'sleeping' was very far down on Tony's list of immediate needs at almost all times.
It didn't feel out of the new ordinary, then, when Iron Man stalked through the unpopulated halls of Hammer Industries and came stiffly marching into the lab, preemptively ready to roll his eyes behind his mask until the rolled right onto their special guest star. "Pedestrian, isn't it?" Iron Man wondered with a gesture toward the uninspired binding method. Hammer, he thought, seemed the type to have all kinds of experience tying people up for his own pleasure; he should have had a certain flare by now. Unless Hammer was emotional about the affair. He did let that get so terribly in the way all of the time; Tony just needed some more information to judge the type and degree before he knew how to approach this fresh hell.
