Nick couldn't help that his grin grew at her words. Maybe a little horrible. Mostly playful, though. "Maybe I'll take you up on that some time. I'm pretty good at making sure I run enough not to get the inner wolf itchy." Nick shrugged, very much used to taking care of this kind of thing. Unlike Elena he wasn't the sort to put it off. It had always been a part of his life, and he wasn't the kind to fight it.
Moving to split his own potato open finally, Nick managed not to react overtly to her preface. He had an idea of what was coming, so when he looked up at her he wasn't upset, but he didn't have that wide smile on his face either. "You can see my wolf side some time, but not the change to it. I mean, I am an incredibly adorable black wolf with dashing brown dusting over my fur, so that's the best part of it." Nick grinned, charmingly.
He didn't want anyone to have to see him change because to someone who wasn't used to it, he was positive that it would seem....well, awful. The sight and sound of the transition weren't fun to watch, and he wasn't going to expose anyone to that.
