Michael watched her with a strangely resigned look on his face and then he turned away to shower though first he said, "I will bring you some dry clothes. You can't stay in those."
He set her clothes near her, since she looked content all stretched out. Then he moved into his bathroom so he could peel the soaking articles of clothing from his body. He discarded them in his hamper and then he stepped into the shower, welcoming the warm cascade of water that heated his chilled skin.
He still had no idea what had happened, but at least he wasn't cold any more.
