Dean wasn't the only one who had his misgivings about the idea. Michael had been very vocal about just how much he hated the idea. They had helped the Winchesters, given them the information they needed for their impending fight against Chuck, they'd even opened a portal into Purgatory for Dean and Castiel. As far as he was concerned they were finished with the Winchesters. He had only softened, only backed down a little when Adam reminded him that Dean was still family.
Maybe he hadn't forgiven him (or Sam) for leaving him behind and forgetting he existed but Dean was still his brother. Besides, Vallo seemed to be good about second chances and something like safety. Maybe he could actually get to know his brother here and they could stop being strangers who shared a father. He supposed he'd like that. He'd always wanted a brother.
Seeing that he was unable to change his vessel's mind, Michael had gone silent on the subject after reminding Adam that he would be watching. Adam simply rolled his eyes. He took a deep breath at the sound of Dean's voice and stepped out of the room he'd claimed for himself. "I'm here." He said, offering the older man a smile. "It's a pretty impressive place they give you, right? When I first moved in I was expecting the something the size of a dorm room."
