I didn't like that the reveal about Tysha, Tyrion's first wife was left out. I mean, I can understand it, I guess. He did mention it on the show, but it was so many seasons ago that the tv viewers probably don't remember/care anymore.
If I recall correctly, though, Jamie reveals to him his role in it, and that it was a lie that Tysha was a whore... which is what sets him off. Feels like a much more powerful motivator, and he is also left hating Jamie.
