It wasn't very often that everyone in Casper high agreed with each other on something, Phantom was either a villain or a hero, the Fentons were either geniuses or idiots, the Red Huntress was either terrifying or comforting, and the Nasty Burger was either delicious or lived up to its name, but there was one thing they could all agree on. There was a ghost among them.
None of them ever really talked about it, seemed like an awkward topic to bring out of nowhere, but eventually everyone realized that they weren't the only one that knew. After a bit it became like a silent agreement to not bring it up, to just ignore it. But it got difficult to ignore something like that.
The cold gaze that seemed to pierce through your very soul, the chill that ran up your spine at the smallest glance, the sense of wrongness that just bombarded anyone close, there was no question about it.
Sam Manson had to be a ghost.
