KoKoa, I didn't mind Val stabbing Yorwrath's arm to get him to let go. That was nothing. It's the potential maiming that has me twitchy, because I can't see Yorwrath being able to go on and remain sane if he's rendered useless.
Contrary to the SB silliness last night, he's a creature of physical prowess, a swordsman and warrior. Take away his ability to defend those he loves, like Aneurin, and those to whom he's loyal, like his people, and he has nothing. Not even the promise made by Caoilfionn that he will share Valentina with Aneurin and Islwyn would be enough. He'd be without purpose, and that's the kind of maiming that's far worse than any physical wound.
And there's a strong streak of nobility in Yorwrath. He knew what would happen if he shed a tear for his wife when Aeron killed her, but he did it anyway. He's willing to die for his brother. And he had the chance to make trouble at the claiming, and didn't, nor did he touch Valentina when he slept beside her and his brother. So, if anything, he's becoming more of a tragic figure than a villain, although I wouldn't say the same thing about Islwyn, who hides his motivation far too well for me to trust him. Sadly, he's the underdog I'm rooting for, and I have the worst feeling that I'll be crying in the next chapter or so.
