When it came down to it, Castiel didn't have much interest in who Ryuuzaki had been back in his own world. It didn't affect them here and now, and so he hadn't put much thought into it. What mattered to all of them was returning to their homes, and Castiel would much rather focus on that than trying to pick people apart.

He took down a few notes as Ryuuzaki spoke, nodding. A few terms and the general time period should be enough for them to find the right Earth, or so he hoped.

"I'll do what he can," he said once he was done writing, only then glancing up to look Ryuuzaki in the face. "Anything else?" He didn't know how much time they had, but they may as well make use of it while they could.
