I think Kiara has way too much money in her "account" so they won't let her win and Leila actually looks like a model, so she is out of the question. That only leaves Laura and she was strong in the beginning so they'll probably do a "come back to the top" edit to justify her winning.

Although i have to admit, after last episode, the way they're editing Kiara makes me really nervous... NO ME GUSTA
