Sol pulled away and sat herself down on the couch. Hard. She told Dean that he was going to hate her, but how could he? He just found her again. She explained that when she got here, she ran into another Dean. He didn't know what to make of that, but he pushed it away for right now, because it didn't matter. Although now that she was telling the story, the 'other' Dean was ... proposing to Bela? Dean scratched the back of his head and decided that this was hell in all it's shitty glory.
What would it have been like if the roles were reversed? First, Dean would gather his bearings and try to get the hell out of this freaky alternate universe, but he had a feeling he wasn't going to like what was about to come out of her mouth, although, there was a twinge of feeling somewhat hopeful in his actions.
Walking over to Sol, he crouched down in front of her and his arms reached out, holding onto her hips while she sat there in a ball on the couch.
"I don't care," he said finally and looked up at her. "I have you now, whatever you did, it doesn't matter." He spoke truthfully because if she went out and had a one night stand or something equally Dean like, he didn't care. It was another moment and another time, that's all it was.
