"Oh, of course," Remus said as he stepped back to give her space...although he didn't really know which way she was going to go, she was just looking up and he realized he didn't mind not knowing either. The moment she disappears, he is going to crack his suitcase open and look for that Essence of Dittany he'd packed along. Lord knows how much he had been itching to find it since having arrived to fancy New York City.
"I'll stay here," he added needlessly. Just in case. Not that she needed him, he needed her. On top of that, he had questions to ask her still. Such as...if he was out of place and she had been so used to his trouble...did that mean that he wasn't the first one to...try it out? Had something similar happened in the past?
He'll have to wait until she'd changed to a different costume. But more than the question, the more pressing need (and desire) in his mind right now...was for an Essence of Dittany.
