Mr. Moxy was being a pain. First, he'd refused to stay back at the room when Natalie had been leaving for a quick visit to the roof. And now, he decided he wanted to explore the third floor rather than follow her up.

It took Natalie a while to realize she wasn't being followed, so by the time she came down the stairs from the next floor up, he was already sniffing around Stiles' open door, because that was what he did.

It was possible he thought something here smelled like a dog.
