They've actually hinted what type of ghost she is in Episode 2 although I'm still hesitant to say she's capable of actions like a poltergeist at the moment. But then they had her pick flowers in Episode 1 so there goes most of my theory's credibility...Jexhius said:Jintan could totally prove that Menma is a real ghost, rather than just a hallucination. He could do it any time, but he doesn't. This kind of thing annoys a certain part of my brain that picks holes in plots.
