Dean quickly moved so that he was covering the opening to the shower. He was getting a little wet in the process, but he didn't care. He would stand there like a damned stone wall if it kept her in there under the cold water where she had a chance to sober up. They had had a lot of good sex in this shower, and though he knew that was likely not EVER going to happen again in the near future, he'd still count it as a win if his Claire came back.
"I'm not insane." he said, trying to keep his voice neutral. "You're VERY drunk, and I told you that we need to get cleaned up and sober up. When Megan's here, we should take Ben to meet his aunt. YOU should go meet your sister in law." As far as Dean was concerned, as well as most of the rest of the family, Claire was family. She might have lost her entire biological family, but she still had family left in spades, and she needed to realize that pushing them away wasn't helping one damned bit.
