"Can dream. We have a portal to master and then we can get parts. Dr. Ingram talks about building a ship sometimes. We could spread the word ourselves, go help others. See other worlds."

A pretty enchanting idea, even if it seems like a remote possibility. It's not one he'll count on. If they're stuck here on this world for the rest of time, he'll be glad that at least he has that much. But it's fun to daydream about the possibilities so long as he doesn't get too hung up on them.
