In the 2013 new release Texas Chainsaw Massacre 3D, the last line in the film is spoken by Heather as she takes the food upstairs from Jed and locks the door. I couldn't make out what she said, and it's kind of crucial to the plot as I don't know if she chose to stay with him or not. Does anyone know what it was?
I'm not sure exactly what she says, but in the post credits scene, her adoptive parents come to visit. As they knock on the door, her "mother" tells her "father" to say he loves Heather. He replies by saying that for that kind of money, he almost does. Then they hear a weird noise as Leather-face opens the door wielding a chainsaw at them. So basically she does stay with him. Hope that helps!
