One of the darkest aspects of atsv is how Gwen was groomed. When Jess and Miguel took her in, I got "vibes," so to speak. The trailers obviously didn't help, but those painted Miguel in a bad light, unlike Jess.
Gwen, a 15-16 year old, goes with these two in the heat of a tense moment. I don't think anyone had ill intentions, but that doesn't negate the results.
I was shocked when we learned that Gwen hadn't gone home in months. Jess and Miguel become her whole world and take on the roles of her parental figures. In this time, she has become emotionally dependent on them and their approval. Gwen is scared to disappoint them. She's threatened with being returned to her dimension with no support, a place where last anyone saw, her father was trying to arrest her for murder.
Jess uses Gwen's admiration and dependence to manipulate her. She knows Gwen fears letting her down. She goes from being smiley and supportive to blunt and cold.
Gwen is scared. Whether they intended to or not, Miguel and Jess essentially groomed and emotionally abused her. The second she justifiable makes a mistake or just acts like a normal teen who lacks interpersonal relationships, they send her home.
At any point did they try to help Gwen reconcile with her dad? What did they tell her so she'd be fine with her father dying?
I know the dictionary definition is more of a nsfw nature, but I do believe it can occur in just a manipulative manner. They took in a vulnerable child, manipulated her, and threw her out.
Her whole arc reads like a kid disowned for coming out.
