Tywin deserves his death all the way. I'm also glad Shae was not harmed though, because in my book she owed Tyrion no loyalty.

I think Tyrion really has a horrible emotional scar from what Tywin did to him with Tysha. Because it instilled this thing in Tyrion that there are no good people. Even he himself ended up being a monster and the best that he can hope for is bought pretend love. And he prefers to be upfront about it.

He would actually want real love but he denies it even exists and so deludes himself, thinking he has it all in Shae. It'll be interesting meeting him after all of this. I think he might have lost his taste for whores.
