Quote from duxI've read all the books dude you don't need to wiki me. I'm just curious as to where you got your information. Are you confusing some of this with the Witcher maybe.
The wiki stuff was just me joking of course. I checked it and apparently I made a few mistakes. I really thought that Brienne was dead due to how Jaime described her (10 years older, pale, etc). The Tywin being poisoned part is actually pretty apparent. I looked up the text for you. You can read it here. I'm 100% convinced of this. It's not a theory. Skalg explained the rest.
