The Tysha storyarch works for the book, but it wouldn't work for the show. In the books, Tyrion thinks about Tysha but never speaks about her. How would you even portray that in the show? You think the audience will be emotionally invested in a character they've never seen?
I think the show handled it better. I like the idea that Jamie/Tyrion still are fond of each other because they're the only ones there for each other.
