It pains me that we may meet under such circumstances but i cannot stand by and watch your cousin abuse a position that should never have been his. His reign will end one way or another, the other Lords will not stand for his tyranny.
I bear you no ill will and once we were friends, for this reason i offer you the chance to return to Casterly rock with your new bride. You will not be harmed in anyway, you have my word. Should you refuse my offer however i'm a fraid no amount of friendship between us will save you once the walls of Kings Landing are breached.
The city will fall Torin, there is nothing you or the Lannisters can do to stop it, save yourself, you owe the little bastard nothing.
