Piper Shaw

Piper Shaw is the hidden main antagonist of the first season of Scream.

Initially claiming to be a visiting pod-castor investigating the new Lakewood murders, it is revealed she is the daughter of the original killer, Brandon James, and his best friend Maggie Duval. After Brandon's death by police, Maggie's parents made her give up the baby for adoption, with Maggie never even knowing if the baby was a boy or a girl.

This drove Piper mad, as she believed her younger half-sister Emma had "the perfect life", while she never got to know her parents. Ultimately, upon finding out who her parents were, Piper decided to plan a "reboot" killing spree, targeting Emma's friends in order to make her suffer.

She is portrayed by Amelia Rose Blair.
