When the tree is 'eating' Robbie and Diane and Steven are helping him, Carol-Anne starts getting sucked into her closet. Why didn't Dana help her? She was still in the house in the next room and with all the screaming Carol-Anne did plus the noise from all the toys getting sucked into the closet it seems incredible that Dana didn't help her, she is definately in the house as there is even a shot of her looking out of the window at the tree and she didn't go outside until Robbie had been saved and the tree 'blew away'
