Ghosts?

Kennedy scanned his brain for some information. He's read a few things here and there, but they weren't source of interest for him. He does remember, though, the stuff he watched in muggle films. In the really, really, really, ancient movies some would wear white blankets and scare people. Really, that's NOT scary.

Though he didn't have specific, full-fact answer he would share what he knew, so he raised his hand. "Ghosts are transparent body forms," he said. At Sir Nicholas' Death Day Party he had seen many ghosts and they were see-through. "And I've also heard that ghosts can't be killed." Because they were already dead, right?
