It's not clear what's going on between the two of them, but it's clear that they're having a hard time communicating. They're both freaking out because the oasis hasn't been found, and there's nothing to do but wait and see what happens. The only thing that seems to be keeping the two apart is the fact that the "spawn" in the desert has hatched, and they need to figure out a way to get back to the oasis. They can't figure out what to do, though, because they've got a bunch of work to do. So they'll have to figure it out themselves.
