the cute is his greatest weapon. also knives. he's a fairly unique ghost since he's bound to an object and has the ability to turn corporeal at will, when most ghosts are forced to use possession instead if they want to interact with the living. aside from more personal questions, he's willing to answer pretty much any questions that come up about ghosts! and he'd also be happy to help her get revenge on her murderer, if she hasn't yet. whoops. he probably won't be incredibly helpful on the parents front, since his answer would likely be "just tell them and make it their problem."
