They're approaching the bar now, and Ned really hopes that it's unoccupied. He wants to keep talking to Charlie, without worrying about being overheard.

Charlie doesn't make much of the story, but Ned thinks it is rather sweet. It must have taken a certain amount of courage, as far as he's concerned. That sort of thing was plenty emotionally complicated in his own time, but in theirs it was more than that. It was a real risk. Was illegal, as far as he knows.

That thought leads him to another, and to another, so that he asks, "If the stuff I saw in his dreams was true... was yours? I mean, about being in prison?" There's something obviously tentative in his voice; he doesn't want to overstep his bounds. Ned holds open the door for Charlie, is glad to see that the bar is unoccupied.
