Relief eased his chest, oddly enough. So - he was in a universe where Vulcan was all right. Maybe he was even in Elder Spock's universe, though at a different time point, clearly. Even so, he gave thanks that there was a universe where Spock and his people did not have to suffer such a calamity, where his other self was spared the guilt of that failure.

"Just a bit of proof that I really am in an alternate universe," he said softly, hands gripping his sheets. "In my world, Vulcan is gone - imploded, to be more accurate." If there was a way to convince someone what he said was true, this felt like one of the best ways. Though, he supposed it could come across as a ridiculous lie. But for himself it was the most glaring point that he could perhaps ascertain where and even when he was.

"Believe me or not," he added. "Though I'm sure Spock and Scotty can come up with several tests to confirm what Bones' medical analysis has already said about me. I would prefer not to, though. Scotty's experiments have a tendency to get shocky, no?"
