Yes, her friend elise

Elise is skinny, has short long brown hair like mallory, a small but and tits, is her roomate, and an absolute bitch. Mallory cant stand her

Mallory actually bought the potion not for herself, but to fuck with elise.

"Oh hey elise" mallory says when she enters her apartment. "How ya been?"

"Good, how about you" elise was trying on her new black yoga pants at the moment, "Im great, nice pants too" mallory responded.

Elise had water to her side that she had taken a few sips out of, but hadnt finished. So as elise goes to her room, mallory slips the potion in and, bam, the clear potion will do its job.

"Hey elise!" Mallory said "I gotta go" she was lying but she didnt want go get tangled up in what was about to happen.

"Okay see ya" elise says as mallory leaves the apartment and stands againts the hallway wall to hear the action
