- Stoker: Implied in two rather unsettling cases.
- First, in the scene where India's uncle, Charlie, saves her from being raped by killing her attacker. The attacker is an Asshole Victim through-and-through, but the unsettling part comes in when you realize — Charlie's in love with India. Not to mention, he's shown following her to and from school before this, and it's never explained how he even knew where India was. He also reveals himself to be a Yandere in the highest degree. This gives the impression that Charlie may have killed his niece's would-be rapist because he was jealous of him.
- Even worse is Evelyn, India's mother, who is infatuated with Charlie. After catching India in an Almost Kiss with Charlie, and subsequentially realizing that Charlie is in fact interested in India and not her, Evelyn's immediate response is not to, say, try and get her daughter away from this creep. Instead, she delivers a Breaking Speech to her daughter, implying that her angered reaction was more out of jealousy than anything else. (For what it's worth, she does tell Charlie to stay the hell away from India. Again, this may be out of envy, but it could be out of protectiveness.)
- Trance: Simon Newton, oh so very much. He's willing to murder his ex-girlfriend Elizabeth Lamb if he can't have her back, and he attempts to kill Franck for sleeping with her.

- The Woman in Red: Didi, Teddy's wife, describes herself as a "very jealous woman."
