"I like being alive, so I tend to do things that will help me to stay that way." He told her with a grin, he could tell she wasn't joking, but then Marty wasn't joking about enjoying being alive and well - he wasn't in a hurry to get himself killed even in the hopes of gaining some cool power.
He chuckled. "You know, since I'll be staying forever, and eventually I'll have to change or something, unless my power turns out to be staying clean." He smirked. It all made sense in his mind the mentioning of socks on the floor and staying forever, it was all just a joke. Even if he was disinclined to leave Savannah's rooms any time soon since he was finally starting to feel warm again.
He arched an eyebrow when Savannah told him there was something better, and was just about to ask her what there could be better than this - knowing she likely wouldn't say something along the lines of another basketball game on the television - when she put her hand on his cheek and then leaned in to kiss him. It wasn't the brief kiss she'd given him earlier, this one was sweeter and Marty actually let himself feel the warmth of her lips against his, perhaps in part thanks to the hot chocolate they'd been having.
"Hey." He'd lingered longer than he probably should before he pulled back setting his own cup down fingers all ready missing the warmth of his cup. "You don't have to do that." He told her, part of him said that kissing he was a really fucking terrible idea, like one of the worst ideas he'd had in a very long time, but there was another part that said that it was a very good idea too, Savannah had told him she liked making out, and she was warm and soft and sweet and he'd tasted just a bit of the chocolate from her drink on her lips when she'd kissed him and his fingers itched to touch her again.
