Bruce returns some time later, with a heart monitor slapped together hurriedly from parts from one of Tony's watches, some other random parts and a little help from JARVIS -- it's not pretty, not polished, but it'll do the trick in a pinch -- and a packet of unfrosted strawberry poptarts. He would have made her a sandwich, since he figures she'll be hungry and there's more than enough food in the kitchen, what with all the other Avengers minus Thor in the building, but he thinks better of it when he realizes how much his dietary habits have changed over the years. While in Kolkata, he became a vegetarian out of necessity, and hasn't thought to break that habit now that he's back Stateside; who knows if she's stopped eating meat for one reason or another, too? Poptarts will have to do until he knows for sure, just something to tide her over until she can get a real meal in her.

Either way, he sets both down on the table when he hears the sound of running water in the bathroom, and settles in to wait for her to finish. When the amount of time she takes begins to grow worrisome, he fidgets idly in his chair -- he'd be lying if he said he wasn't grateful he could still worry, when he seems incapable of true anger at the moment -- and then gets up, moving to the bathroom door. He spends another few minutes lingering there before he finally decides to knock on the door.
