There was no way back, then. Unless Ryusei had lost his memories, too, but.... He looked down at his hands. Kengo had healed the injuries there, but everything else on Ryusei's body was evidence of the fight with Tatsugami. There couldn't have been any memories to lose. Gentarou.... Hopefully Gentarou had made it out the actual door and was even now protecting the others.

Ryusei put his elbows on the table and bowed his head behind them to obscure the expression he was making. It was a reflex, as it was for most people, to hide the tears.

He had to pull himself together. Ryusei had asked Kengo; Kengo didn't have injuries consistent with a later time, either. Something else was going on here. But then again, Kengo was....

Kengo was dead; the fact that he was here was evidence of 'something else' going on, not the memory loss. If Kengo hadn't found a way back and Ryusei was here.... Ryusei was going to have to consider everyone dead. If they ever got back to Earth, everyone would be dead from the ravages of time. If no one here had heard of Cosmic Energy and there was no Gate Switch and there was no getting off this asteroid, this was what Ryusei was going to have to deal with.

"I won't... disappear," he said in a whisper to minimize any other sound he was making. "I won't leave you, too."
