Carrie caused the crash of Oceanic Flight 815.Note: the following is based on the remake. Chris somehow survived after Carrie threw the truck she was in against a tree. Afterward, she changed her name to Claire Littleton and moved to Australia. Carrie found out that her old nemesis was still alive, and followed her down under to kill her. When Chris/Claire got on the flight to Los Angeles, Carrie stowed away in the cargo area and tried to wait until the plane was out over the open ocean so that she could get her revenge. Unfortunately, the EMP from Desmond's missing of the button caused Carrie's powers to go berserk, bringing the plane down early and in the South Pacific, which is filled with desert islands that a plane can (semi-)safely land on. The reason there were survivors at all, then, would be that Carrie, as the plane was going down, instinctively used her telekinesis to buffer the crash-landing. She never shows up on the island because she was in the cargo area, and, still reeling from the misfire of her powers, was crushed by the plane. school in Westchester run by a man with a history of helping people like her.
Sharon da Silva/Alessa Gillespie is another one of Carrie's half-sisters.It's established that Ralph White, Carrie's father, can't keep it in his pants, as evidenced when he cheated on Margaret and produced Rachel Lang. Sometime after this, Ralph moved down from Maine to Silent Hill, West Virginia, where he continued his philandering ways and fathered another child, Alessa, with Dahlia Gillespie. His whereabouts afterwards are unknown, and don't matter. Like Carrie and Rachel before her, Alessa also began to manifest psychic powers. This attracted the attention of the town's cult, which felt her to be a witch, and they tried to "purify" her. Alessa survived, but horribly burned and locked away in the hospital. Without use of her body, her powers strengthened as she relied more and more on those, like a blind man who comes to rely on his hearing. Worse, her abuse at the hands of the cult turned her into a monster of hatred and rage, and she channeled her power into exacting revenge, mind raping the townsfolk and creating the horrific Otherworld. Around this point, Sharon split off from Alessa as the last remnant of her innocence and purity. Hey, it explains why Alessa/Sharon and young Carrie both look like Jodelle Ferland.
When Carrie dies, she ends up in All-World.After all, like Jake Chambers said, "there are other worlds than these." Likewise, it's where Jake and Father Callahan ended up after their deaths. Hopefully, like Father Callahan, she eventually finds redemption there.
Lot Six was synthesized from Carrie's Pituitary Gland.Unlike the movie, in the novel Carrie died from her knife wounds in an open space rather than be buried under a collapsing house. It's safe to say during the FBI's interviews on the subject, The Shop took Carries body and used her Pituitary gland to create Lot Six. The Drug that later got injected into Andy McGee inadvertently creating Charlie.
