You put your focus into the swim, into the rhythm. There's no sense in patronizing or belittling the humans. It's not long until the wreck edges into your field of vision.

"OK," says Flynn. "I'm curious, though: Do you know how this ship ended up here?"
You're not quite sure, but you do have some plausible explanations.
