Don't mouse over this you showfag asshole wanting to be spoiled! . . . . Theory and evidence that Oberyn actually poisoned Tywin: http://boiledleather.com/post/24196234491/tywin-lannister-dead-man-shitting Looking back, it almost seems obvious. I never caught on though. Any future significance? Probably not, but it's fun.
Never caught it either, it is certainly plausible. I am not quite sold though but the attention to the smell makes it a possibility IMO
Maybe, but I don't think it'll matter. Tyrion still shot him and nobody thinks it was oberyn, plus oberyn is dead already.
Maybe I'm missing something but is there any real evidence other than they ate together at one point and then his corpse was rotting worse than usual?
Not sure, but it doesn't change anything. I actually liked it better when I just thought it was Tyrion.
