The Haunting of Sunshine Girl: Is Nolan back?

So this happened. It was really weird. At first I had a really weird feeling that something strange was going to happen and then it did. But I wasn't expecting this. Nolan just knocks on the door but he seems to be out of it, and he wanders into the house and then disappears. At least that's all I can describe it as, disappearing. But the crazy thing is, he appeared at the door again. I don't know what to think.
