So apparently all of this is right off the coast of Agrabah. Damn. Anyway:

Saleen was expecting a sailor. I suspect she just likes killing men. We get hints that she does this often. She appears to be a siren in the typical sense: she lures men to their death and being alluring TO them is part of the fun for her.
What I find interesting here is once she sees Jasmine for what she is, she gives her the ability to breathe under water.

This struck me because initially, she is actually very friendly toward Jasmine, in a Mean Girls “we’re so totally sisters now” sort of way. She chats with her like she hasn’t had someone akin to her to talk to in ages, and she even has her hairdresser fix her up.
It’s when Jasmine doesn’t seem willing to join her in the man-hating that she stops being so friendly.
There’s problems with this, that goes with the whole “Other Women” issue. We’re being presented with a character that is at first friendly toward Jasmine, opening up the potential opportunity for female friends and camaraderie, but the Other Woman is like that. She’ll be nice to you at first just so she can go after (and in this case likely murder) your man.
I am deeply troubled by the fact that this is the first real interaction Jasmine ever has with another woman in this show.
