Okay, so, Butch and Vishous and their unique relationship. I hate it when people try to label them because labels involve generalities. What is going on between Butch and V is very specific to these two personalities.
Again, I warn you, I am NOT a spoiler-free zone. I'm about to reveal the coolest part of the book, so if you haven't read it, stop reading this and go read Lover Revealed. It's a better read, anyway.
At the end of LR, Butch is inducted into the Brotherhood. Here's how the ceremony works: each of the Brothers bleeds into a cup, then bites the new Brother and takes a sip of him. When they are finished biting the new guy, he drinks the blood in the cup. This is how they become brothers--flesh of each other's flesh. When V bites Butch, it turns into a very erotically charged moment and they get pretty close. Oddly enough, I didn't see it as a sexual moment when I first read it. It is actually the very definition of sexual: they get physically close in a very sensual moment brought on by emotional intimacy. This scene is yet another example of how gifted a writer JR Ward is. Her descriptors, her phrasing, and her bravery in even writing this scene are amazing.
So V and Butch get up close and personal and it's pretty damned sexy. I still don't think they were ever sexually attracted to each other/desired each other that way. But they got physical in that moment because it progressed from their emotional intimacy. It was a one-time-thing, of course, because they are best friends, not lovers, and Butch is mated to Marissa. But I think it was a good thing that they had that moment, especially for Vishous. His sex life is really hardcore and he distances himself from the females he's with; he deserved a moment of embracing and being embraced by someone who loved him unconditionally.
This, of course, means that I am going ABSOLUTELY INSANE waiting for Vishous's book, Lover Unbound. It CANNOT come fast enough for my taste. His female is a human trauma surgeon and we're speculating on her like crazy on the boards. I really think that we'll finally meet Lassiter, too, because every time he's been on the boards, it's been to clash with V and they obviously have a history. And I think that John Matthew will transition in LU because it was remarked that he's getting close in LR.
I really could go on and on about this book and this series, but I'll spare you. :)
