If it's rape, it is the lowest form of rape there is. On a scale of 1 to 10, with 10 being the most vile kind of rape you could think of, what Adalind did was a 0.5 at best. There is a HUGE difference between a woman that gets her clothes tore apart and her body being abused by a guy (we'll compare it to the worst, here), which leaves her with PTSD and many psychological problems, and what Adalind did, which did little to nothing on Nick's psychological state (why should it? at the moment he was consensual). Come to think of it, Nick was only annoyed at best. Also, Adalind did it out of revenge, which I would argue is not your standard rape "motivation". She needed to do that precisely to take away his powers, it had nothing to do with taking advantage of him physically. I would also argue that a man raping a woman and a woman raping a man is completely different as to the consequences afterwards (you may not agree, that's fine). Finally, Adalind did change. It's very obvious that the gang affected her in a good way, especially Nick. If Nick is like me, and I suspect he is, he is willing to let a chance to the people who really do want to change, and we all deserve that. That would be different of course if he was still traumatized from what Adalind did, but he isn't and has never been. All in all, what Juliette did is 1000x worse than what Adalind did. If for some reason Nick/Juliette get together again, THAT would make no sense. The Nick/Adalind pairing is much more believable.
