Main Cabin
That's a fairly good point, but Justin lived in an underground den of thieves for sixteen years, and in a city with limited water resources for another year and a half before coming to Nexus. Learning to swim would be almost impossible. Maybe he'll stop beating around the bush with his back story and tell Brand that, rather than unloading another pile of horse-"I always figured I would know what to do instinctively. You're born knowing how to walk, even if you can't actually do it. I figure it would work for swimming too."...crap.
