I think she'll fine with other princesses except Merida.

Honestly I think she'd get along well with all of them. I only picked Merida because I think Elsa would be uncomfortable with her decision to try and change her mother, but I absolutely think she would understand and connect with Merida's fear of being forced into a role she didn't want.

I think she might clash with Merida. I think she would struggle with Tiana as well, as I think Tiana would be less tolerant of her fears.

Tiana doesn't like passivity, which is why she harps on Naveen so much. Elsa is extremely passive. So, duh. Tiana would not get along with Elsa at all.

Is there another rigging happening? How can there be a bunch of votes for tiana when there’s only been one comment for her?

Yeah, Elsa would like Tiana.

But her or Ariel.

Jasmine is very headstrong and speaks her mind, and Elsa is very reserved and tries to be polite, so I think their different personalities might clash. Although they might still get along as they both ran away from their kingdom to be free.

I also don't think she would get along well with Merida, but the two of them might relate well for their belief in not marrying a man they just met.
