Clark confronts the captain about strange events, including the most recent. He had caught the helmsman sailing a wrong course.
A storm approaches, and again the helmsman is confronted, but has no excuse. Clarks suspicions are not satisfied. As Superman, he flies back to Metropolis, trusting the crew to handle the storm as it increases.
Jimmy comes onboard to join in with the adventure and drama of the crew.
PS: What? Clark is suspicious as danger approaches, so he leaves the ship? And a crew that would let passengers on board, especially kids, when a storm is brewing? It’s a situation just ripe with stupidity.
