OKAY so first off she wasn't entirely sure what trolls were supposed to be, at first, Feferi included. Since there are aliens in canon, but they're from the Moon and....basically look human on the outside, so hello person with gray skin and horns who is also apparently a vampire??? alien vampire, what??? Which is kind of hypocritical since she's a Strange Supernatural Creature herself, but.

She actually likes Kanaya a lot, hahaha! Aside from the obligatory gratitude for sticking the season out and being a part of Team Fuck The Producers Over For Good, she really admired her intelligence. Even if she was a bit, UH, blunt(??) for Yuyuko's personal tastes she knows she has a good head on her shoulders :V Also being one of Kaoru's weird friends sort of gives her bonus points, Yuyuko has a bias.

a+ choice in friends fef, would personally befriend in murdertown
