This is based on opinion. Please don't list it on a work's trope example list.
Pilot
- Megan is watching TV when all of a sudden, the programme switches to a scene of a group of surgeons operating on a person. Then the whole thing becomes real and Megan is the one laying on the operating table, while the creepy doctors try to sedate and probably vivisect her.
The Harvey
- Cindy, nonstop. The way she manipulates Jamie,the young boy, by telling him that, if he leaves her, she would jump from the roof of the house. She even points out how her bones would break and blood would come out of her eyes.
Then the reveal of what she really is, an ancient evil demon looking like something straight out of a nightmare.
- Also Luke telling Susan what happened the last time he trusted a ghost/demon. Apparently this thing promised to be no danger to the family in which house it was living, only to kill the entire family and burn down the house. To top it all of this thing, whatever it was, dismembered or ripped the entire household to pieces.
A House Is Not a Home
- The creepy ghosts of sailors, who try to kill Susan by making her spit out gallons of seawater. Did I mention, that they were horribly screaming the entire time?
Quarantine
- Just the Roadie possesing August and Zooey-
- It first slips into August and makes itself known by extending poor Augie's limbs to an impossible size in a very uncanny way. Then it possesses Zooey, who is first seen clinging from the ceiling like a spider and then very creepily climbing down the wall, all while making the most unsettling growl ever.
Forever Young
- There was a third Roadie, who now possesses Megan. She actively tries to lure Luke to her, probably to kill or possess him, but gets a visit from Susan instead. The way she reveals her true form ist just *shudders*- Spinning her head around 360 degree.
