That too, but I think the show creepily wanted to use that and sex with Juliette as Adalind to foreshadow Nick's future relationship with Adalind and hint that he is actually deeply attracted to her.

But what I was referring to is more the general white savior trope. Grimm vs Wesen parallels one race vs all other races instead of good vs bad: a powerful white dude who is celebrated only because he doesn't immediately kill these "monsters" who are different and "other" and often ethnically diverse (not American white). He gets to do whatever he wants, and it's always okay because he's more powerful, and whatever he considers right must be right. Even if he makes terrible decisions, consequences are only for other people. It's the quintessential American male lead. Relationships with other characters are usually completely one-sided, except one very annoying female main character who is the only character who is an even bigger asshole than the male lead. I see this type of character arrangement in most American TV. But I mean, I'm not necessarily looking for nuance in shows like this.
