Sister Murphy (forename unknown) is a theater major character who appears in Scream 2 (1997 film). In 1997 (continuity error), she was present on campus during the Windsor College Murders, though she was not a target.
She and her best friend, Lois, are shown to be two of the heads of Delta Lambda Zeta, a popular sorority on the Windsor College campus, during Ghostface's second murder spree. She is also a theater major, partaking in Sidney Prescott's starring role as Cassandra in the Greek Agamemnon play.
Murphy is a beautiful, tall, blonde-haired sorority leader seen as one of the heads of Delta Lambda Zeta. She comes across as a little fake to Sidney, as she and Lois attempt to persuade her to join the sorority.
She and Lois find Sidney and her friends watching Gale Weathers give an interview to Chief Hartley due to the murders of Maureen Evans and Phil Stevens at a theatre the prior night. She greets Hallie McDaniel referring to her as "pledge", but addresses Sidney by name.
Hardly remembering her name, Lois asks if she will be bringing Sidney to their mixer later on expressing clear interest in Sidney joining their sorority. Sidney is polite, but expresses disinterest. However, Hallie speaks for Sidney as she is about to excuse herself and says they will be there.
Once they leave, Derek teases Sidney, asking if she will dress like that once she gets in. Sidney quickly assures him that is not going to happen with getting in or changing how she dresses. Mickey attempts to talk behind their back to be interrupted by Hallie who has pledged.
Later, Hallie and Sidney are greeted by Murphy at the party, which Murphy makes a fake gesture saying, "No, I really mean that. Hi!" They ask if they want a drink, but Sidney and Hallie insist on getting it on their own.
Throughout the party, Murphy and Lois really push their bias of their sorority and talk about their sexual preferences "within" the sorority. Sidney politely says she will think about it, thanks them, and walks away to find Derek to their dismay.

She later accompanies Lois and says something is up at the Omega Beta Zeta house as police are all over.
After Sidney is chased by Ghostface in the house, Dewey Riley attempts to track Ghostface, but only find Murphy and Lois wondering if everything is alright in their residence.
Both are present at Sidney's freak-out during the rehearsal for the play. They are seen once again when Derek sings to Sidney in the cafeteria. At first, they seem affronted that he would do that, but later seemed amused.
Tradition for frat boy takedown: Sorority sisters cheer on Derek's capture.
However, Murphy and Lois may have been responsible for telling Derek's fraternity that he gave his letters on his chain to Sidney as means of commitment to her. Though, Mickey also likely informed the fraternity as part of his plan to frame him.
They are later seen as the frat boys kidnap Derek for giving up his letters; they accompany them at the prank party with Derek tied up in the auditorium. Unbeknownst to them, Derek is later killed after they left him tied up. It is unknown how the sorority girls were affected by this.
