Ahmed Ahmed is calling for a "high quality" research trial
By Scream 3, she wears her pain in the form of a necklace that her slain Scream 2 boyfriend (Jerry O'Connell) gave her. But as the movies go on, Sidney needs to be tough, not sad, lest the fun be lost amid the grief. Here, at last, the Scream franchise gives her the space to talk about her trauma outside of platitudes. Through striving to rescue Tatum, Sidney is processing the loss of her friend, and coming to understand how she can share this horrific part of her life with her daughter in a healing way.
