It actually took a moment for her to notice what he was doing, since she was so focused on taking her jacket off that she just assumed he had been grabbing the sheets and putting them on the bed.. but now she did look sideways at him now she was done, she could see the wolf practically trying to dig into the bed, the way a regular dog might to make a place to sleep.

Instinct kicked in before reasoning, and so Ange couldn't help but first react as if it had been a regular dog doing that, even if she had heard his voice in her head again just now. "H.. hey! Cut that out!"

It wasn't until she reached over as if to stop him that she realised that maybe it was just another one of his silly jokes while he was stuck in this form - and that she was falling for it yet again.
