"Right," Severus answered with a nod. When she mentioned pop-tarts, and most certainly did not take him up on his offer of scrounging breakfast for the two of them, he took that as a 'no' on having breakfast together at all. Well, he wasn't sure why he might have thought that in the first place. Other than he rather assumed she might have missed him, as well. Not nearly as much as he had missed her, obviously, but ... well. Whatever his assumption was, it appeared to have been a faulty one.
"I, ah, suppose I'll leave you to it, then," he muttered, pulling himself off the wall. At her question regarding a party, however, he shrugged, shaking his head. "You're asking the wrong person, I'm afraid. If anyone were planning a party, I'm sure that I'd be the last person they'd invite." And with that, he turned to go, and gather up the still full trays of food Lily had brought him before, to take them down to the kitchen. Perhaps he'd look around and see if there was a library here, as well. Because for some reason, he no longer felt at home in his own room. He wouldn't want to force his company on her anymore than absolutely necessary, after all. So, the library -- if there was one -- it was.
