Bruce couldn't help himself - ever since his accident he was always, on some level or another, conscious about his condition and how the Other Guy could make an appearance. Some times, like Tony's beach party when he was relaxed and at ease, he was more like his old self. However, the 44th floor of an apartment building in the middle of downtown Metropolis? That was a different story.
The groceries he brought had to be purchased at a store that specialized in Indian groceries, since he promised Greer he would make curry, among other things. While hiding out in Uttar Pradesh, he happened to pick up a number of choice recipes to add to his repertoire and he was looking forward to trying to recreate the dishes in a Western kitchen. That is, if we wasn't so anxious.
Greer was trying to distract him, bless her. For that, he was grateful, so he didn't want to spoil what might turn out to be a very nice evening. He walked into the room and looked around. "It's cozy," he replied, meaning that it was small. "But for one person, it's perfect. Rent's got to be expensive," he added as he wandered, not to the kitchen, but to the large windows, which gave a magnificent view of Metropolis, below. Still holding the canvas, recyclable shopping bags, he had a horrifying vision of himself, as the Hulk, on the rampage - smashing through the glass to leap down and wreak destruction upon the city. For a moment, Bruce thought he could even see the reflection of the Hulk's face in the pane, instead of his own.
