Marie is very popular this chapter: two girls and the crown prince.
Ahem.
Anyway, maybe Rachel is smarter (and less of a bi-) than Ariel and wants to get Marie on her side because she knows Marie serves the crown prince.
Well, I guess we'll see next chapter? I hope she's not as nasty as that Ariel.
Also, can't the crown prince just... accidentally talk about Princess Morina while Marie is in hearing distance?
