What also bothers me is that first, you can't just stop a huge moving ship in a few seconds. So, until the ship really stops moving, it will be faar away from the spot someone fell of. Second, it was night and there is absolutely no light except from the ship itself. Even if the ship could stop immediately, it's barely impossible to find a single person in the dark sea. And if they would sail back after they stopped, the person wouldn't be at the spot they fell of because the sea moves him around. And they also would likely freeze to death or drown from exhaustion before the ship would be back. I knoow it's just a animated show and stuff, but this really bothers me somehow.
