The recut version doesn't make sense the way it's filmed and was different from the script.

In the original ending that was scrapped after Heather O'Rourke's tragic death, when Patricia jumps through the glass pane into the apartment, she finds Carol Anne, Donna, Scott, Bruce and Tangina frozen and dying. She then also becomes imprisoned in ice and gets attacked by Kane and her evil mirror reflection who want the necklace. Patricia tries to repel them and declares unconditional love for her family, but trips over frozen Tangina and falls to the floor. Suddenly, Tangina frees her arm from the ice and grabs the necklace. She convinces Kane that she is the one who can take him to the other side, not Carol Anne. Kane puts his hand on the necklace, but instead of ascending, his face cracks and he explodes. The blast frees everyone, but annihilates Tangina and causes a violent thunderstorm. Patricia, Carol Anne, Donna, Scott and Bruce finally leave the mirror dimension. Carol Anne sees a reflection of smiling Tangina in the mirror who waves at them and sheds a tear. With the shot of a rising morning sun, the movie ends.
