Jack's expression hadn't changed much until Castiel took his hand. Then he smiled, a bright smile that reached his eyes. He'd done it. He had his family back, even if they didn't know him, or all he had done, or they had experienced together, that was okay. This was fine. "Thank you." He spoke lightly. That awkward nature showing again.

"I will try to not let you down, I am happy to be here with you all. You're my family." His eyes went to Sam then, still feeling happy from all of this. Everything else he could dwell on once he could be by himself. "Thank you, Sam. It means a lot." It did, Sam had always been kind to him, even when things were very bad Sam did his best to keep the peace and Jack could never think him enough.

Sam had been the first human he saw when he was born.

"I do admit, I feel... strange." He admitted. "I can't use my power, but they said that is normal. I think I may just be tired. I saw Dean and Jo earlier. I had never met Jo before... Settling in sounds good."
