Chekov had to admit, Roxas' explanation of what he'd been referring to left something to be desired. He could at least comprehend that Roxas knew something about... black hole-like tunnels. Which weren't exactly what they were all experiencing, being that they were at least remaining in their own dimension (supposedly), but it was at least something to question further. Where did these tunnels go? How were they formed? Why couldn't he and Captain Kirk go through one of the tunnels Roxas was referring to?

He didn't press the issue however, due to the fact that Roxas looked as though he were about to be ill. If the other young man were Starfleet then Chekov would have urged Roxas to divulge as much information as he knew. However Roxas was a civilian, and looked as though the travel was beginning to wear on him.

It concerned him, the thought of continuing through these unknown entities without any information--especially when Roxas was looking to adversely affected. However Roxas was echoing Chekov's earlier recommendation that they leave before something made them unable to escape. But without anything to go off of, who knew? They could step through the next door and never come out.

Chekov's eyebrows came together and he looked up at the Captain for orders. "If zis plece is ze origin point of ze reanimated bodies, it would be to our adwantage to leawe as soon as is possible, Keptain." Even if they had no readout on what it was they were using to escape. He looked back to Roxas, frowning slightly.

"Are you going to be able to stand anozer tunnel?" he asked, offering an arm to assist Roxas if he needed it.
