Yeah I thought that too, but then it would make a lot more sense for her to use the Dressphere to sing as herself, so the crow will be cheering for her and no for Yuna... or maybe she had a weird fixation with Yuna, she wants to be one with Yuna, she wants to be inside Yuna...

Mmm that made more sense that it should. No wonder she prefers to be massaged by her female goons.
