In the opening minute of the show, we have our first sighting: look at that face between the rails.
As Hugh and Steve run out of the house, a figure is standing to the left of the staircase.
Look behind ya, Hugh!
See that face in the glass? Chills!
Addams Family homage with the Uncle Fester look-alike back there?
Look at the back window.
One of the creeper ghosts, this one is hiding under the piano and is likely responsible for the writing on the wall that Nell got in trouble for.
We wonder what hair growth supplements she takes.
Creeper in the archway alert.
One of the more obvious and visible of the hidden ghosts TBH.
Believe in ghosts now, Steve? This was the finale's only hidden ghost (it seems), with a figure standing behind the eldest sibling.
