|“||Like I said: every new class at Keaton has their very own "Bianca Blackwell". Mine was Trisha Marmaza.||”|
Trisha used to be mean to Scarlett and presumably other students. Still during her first year, Trisha dropped out of Keaton when it became close to Christmas. She was labelled as "The Christmas Dropout".
Trisha shares some traits with Bianca: she can be very rude and thinks that they are the best.
Not much is known of Trisha's appearance, except from that she had straight, glossy hair.
