So true.. and you have to read the novel. It was an unsettling scene. Also yes, to him inducing heat to the twins becoz they were about to rape him, thats what it was.
I have a thought regarding the forced comedy we're seeing. I think it was because it was seen in grayson's pov, and he has always an innocent way to feeling emotions. I dont know if it's just me though.
Here, dane is not "mindless".. he's aware which is worse. We've seen a first: an omega forcing an alpha who is not consenting. Maybe, just maybe, thats author's intention.

I'm okay with dark humor, but not with rape. The forced comedy amidst a rape scene is weird. I know they showed Grayson inducing heat in omegas in the beginning (but it was literally to stop them from taking advantage of him I think??) but Dane didn't know that. Idk if that's why the author made him do this, but let's be real, idfc how horny you are I'm tired of the "mindless bimbo rapist" that they always show heat/ruts make omegaverse people become.
