The ship's axe-murderer is 10x better now too.
I've added hints of him in two spots (ex: mysterious hulking shadow from odd direction when all characters are accounted for) and given MC plenty of time to wonder who that is.

Then can have her go the captain but he'll be like "No one matching that description on duty" or something. When he finally shows up for the first chase scene, it's going to be such an ah-ha moment.
