No. Did we read the same thing? Grayson wanted to do it normally cuz he wanted his true love and he was obsessing over the fact dominant omega cuz of his dad koi he wanted a dom omega. If he slept with dane in heat it was not by the choice but due to pheromones and instincts. That's why he didn't want that but ultimately submitted cuz dane induced his rut. And Grayson even though enjoyed but it was due to induction of rut he didn't like it as it was just RAPE. He mentioned it later.
I'm sorry I was saying how yes Dane kidnapped him, but he willingly went along with it to get Dane trapped on the island so that he could eventually induce his heat because he wouldn't have any meds. Not defending Dane, but its strange how Grayson is panicking when he was essentially trying to do the same thing. I'm not sure how else to explain this for it to be understandable.

I thought the point of trapping Dane there was for him to eventually go into heat cause there are no meds on the island. Then he wanted to have sex with him and check for the mark? So isn't that rape as well? Why is he acting he wasn't going to do the exact same thing?
