When Jane entered the house, she saw Jon and Zoe in the living room. She was shocked (but maybe a little happy, as well) to see that Zoe had changed.
Zoe wasn't Goth, as she wearing a light blue T-shirt, a pair of jeans and sneakers. All of her piercings, tattoos, and black make-up were gone and she no longer wore a spiked collar. She looked quite wholesome and looked like a more normal teenage girl.
Apparently, the stone didn't just make them get along with each other. It changed Zoe so that she would have more in common with Jon, so then they would get along with each other.
