"It's magic," Klaus said simply, that was answer enough for him, though he supposed if you really thought about it they probably had to come from somewhere, but that was the sort of thing that wasn't all that important to him. Because it ended up with them at a table with coffee and tea and food first thing in the morning and what could be more important than that at a time like this?
Ben was - well he was Ben, Klaus doubted he'd ever truly get used to having him there. Though maybe if he had long enough. He was less and less concerned about the idea that he might just disappear, but the reminder that he was solid was one that Klaus liked. His brother had been a constant companion for years now, and in all that time he'd never been able to touch and now that he could - well Klaus found that he did so without thinking, simply because he could.
"You could, it'd be the polite thing to do." Klaus said with just a hint of a smirk, as if his brother asking about what he already knew could be considered anything of the sort.
"It was a very good night," He added though, because Ben seemed interested in Bill. "He's very flexible." Because it was true, and it was the sort of thing that Ben ought to know. "You should see the other kinds of magic he can do." Klaus teased as he picked up his cup of coffee grinning at his brother over the rim before he took a sip.
