Because of her appearance, Fujiwara-san is assumed to be good at classical literature, even though her talent is in English, having replaced Olivia in the English speech contest and won. She's exasperated by all of her classmates who come to her to ask for help with classical literature during break time, and she comes to Olivia for someone to speak in English with.

I think you have, like, five screws 
loose in your head, though.

cinco parafusos faltando na cabeça!
Но раз ты спросила, 
то ты очень странная, с твоих слов.
