Maybe all that buys Thomas some measure of undertanding and leniency from the Svartelves, but does that help how the Svartelves view Harry?
... if Thomas has a trial a lot will come out.
I could see the duress being a reason the svartelves to forego killing Thomas, but he still murdered one of their own and a very high weregild would still be demanded.
This, so who is going to pay it? The White Court, since Thomas is a vampire, or the White Council because Thomas is the half brother of a then White Council member, Harry and the grandson of Eb who not only is a member of the White Council, but a sitting member of the Senior Council.. Even if Eb claims he didn't know, would they believe him?
The Whamps (specifically, Lara) would pay it.The White Council would not -- Thomas is a Vamp, it's Vamp-business.I suspect Eb hates the very idea of Thomas existing, and would just as soon the Svartalven vengeance erased that blot on the McCoy family honor.
