He squeezes his eyes shut. Doesn't want to think about it.

"I backup and duplicate my files and memories regularly, I don't know what all will disappear with me if I'm lost to the void. I've tried to make them as intuitive to read as possible. We'd better find each other again after that...but if not."

He bows his head. "I wouldn't want to push him to the limits I've pushed myself to in the past. That's not fair to him. But as long as the train insists on dragging my soul across the universe, I'll keep fighting. For everyone to have freedom and choice."
