I think all the classic princesses would get along with any of the other princesses.

I think her personality is too strong for Aurora.

too blue eyed blondes? rivals!

Snow white? Cinderella?

It's quite hard to judge, but I don't think she would completely dislike someone. She'd be always polite and them who she wouldn't like so much probably wouldn't like her so much either.

I actually can see her and Jasmine as friends. sometimes strong personality + easygoing personality can work really well. My bff and I are the same way. Jasmine is a romantic and can't always save herself, so they do have things in common. I definitely see Jasmine from the show being open to friendship with someone like Rose.

She wouldn't hate Mulan because as others said, the Classics would be polite and civil with everyone probably, but she wouldn't be close at all with her for obvious reasons and vice versa. Unlike you think their relationship in OUAT had some truth to it.

Now that Merida's here I could easily say her lol but even then...I think they'd get along.
