About me: Bio for now, layout later. SPOILERS for those who have not seen the latest Scream.
Samantha "Sam" Carpenter is the main protagonist of the Scream (2022) reboot. She is the elder sister of Tara Carpenter and ex-girlfriend of Richie Kirsch. Having run from a troubled past, the former Woodsboro resident returns to her haunted small California hometown to aid her younger sister against a new Ghostface entity.
At age 13, she discovered the secret of her birth origin — she is the biological daughter of original Ghostface serial killer, Billy Loomis who derives from the original Scream (1996). Correspondingly, this also makes her the paternal granddaughter of the first copycat Ghostface killer, Nancy Loomis, who appeared in Scream 2 (1997).
After her legal father's abandonment due to her birth origin revelation, she spiralled into a life of drugs and crime. This dismayed soon-Sheriff Judy Hicks, who Sam would babysit the son of. At age 18 (possibly almost 19) — with Woodsboro no longer serving her any good — she abandoned it in favor of another California town.
In her departure, Sam did not say goodbye to her mother or baby sister (then age 13). Now 5 years later, Sam is confronted with both her troubled teen past and birth origin — she is Ghostface's primary target. Now a 24-year-old bowling alley attending, she joins forces with original legacy franchise survivors, Dewey Riley, Gale Weathers and Sidney Prescott, to stop the new killer.
In the end, Sam proves to embody the rules of a real-life horror movie legacy "requel" (reboot and sequel); she is both the descendant of a legacy character, and the new Ghostface entity is her own boyfriend, Richie whom she is able to kill (staying true to the original Sidney-Billy dynamic), as well as his accomplice who lives at 261 Turner Lane, Woodsboro (Macher residence), Amber Freeman.
