I only found out that Tyrion is supposed to be dead at this point, I was curious as to how that would work cos that would mean he doesn't have much of an impact on the rest of the storylines, does that mean they write someone else out and give him their role ?.

Sansa is meant to be stuck in the carriage but it looks like they're building a storyline for her that has nothing to do with or is yet to be finished in the book series ?, wtf ?

Ahh, I heard off a friend who heard off another friend that Tyrion never made it past the trial by combat, so would've died at the end of season 4 ?. We assumed he was taking over Varys role (killing Tywin / finding dragon lady)

Sansa I find interesting though, same mate told me but that is a big divert from the book, unless they reset her storyline after whatever they have planned is finished.
