[arthur]

Peter's soul is forced out of his body and the soul of his dead sister is put into him. Turns out that she is the new reincarnation of one of the 8 Kings of Hell, and now he has a new body in young Peter and has come to start his dark rule again.

Henry, the kid who bullied the seven friends when they were kids, was almost killed by IT, and took the blame for ITs crimes, breaks out of the insane asylum hes in (with ITs help), and stabs Mike, who goes to the hospital (Henry is then killed with his own switchblade). Then, Richie, Ben, Eddie, Bev and Bill go to the underground like place where IT lives. First, IT appears as Georgie, trying to get Bill, but they stop IT and continue. IT is in the shape of a large spider. After IT kills Eddie, Bev kills IT with a slingshot by shooting silver through its heart. They follow IT back to ITs hideout in the sewers, and tear it apart. Then, Bills wife Audra (captured by IT) is then saved by Bill. Richie then gets a part in a movie. Ben and Bev got married and Bev got pregnant. Bill and Audra packed up, ready to leave the town. Audra had been in a shocked, unable to move or speak state from being captured by It, but does wake up from it.
