That's because DeSantis had a certain aire about him.

To use your guys' bist analogy... if the boat was a life raft holding survivors of a hurricane, DeSantis is the feckless idiot who would fall asleep on watch allowing the boat to drift behind the mainland out to sea, get a but up his butt that people start looking to the one person who keeps them calm by pointing out that they'd be able to tell if they're in a shipping lane once the stars xome out and pitch them overboard to the sharks, then panicked himself once he realizes ehat he just did, get fussed about the impending hardship and pitch the only person who knows how to set up the water distiller overbiard so there's more food to go around before even checking to see if there is any. He's just useless. Hes the guy who makes bad situations worse. At that point you don't bring up that you know how to use the fishing equipment because the sharks have sure figured out he likes to discard edibles.
