Nobody knows how it ends expect the author and to some extent the show's creators, anybody posting spoilers has probably read all the books published so far so nothing you can tell them they don't already know.
Only the author GRRM knows the ending, the rest of us still wait for the 6th/7th book.. Agree that, those that post spoilers know what happens so far.
The last book isn't even out yet
I am a keen game of thrones follower however since I am in the middle of my exams I was not able to read or watch the latest episodes until recently. as you can imagine episode 2 of the fourth season portrayed an interesting and delightful turn of events for many enthusiasts but with this there came a few individuals who wanted to spoil this fun for others. I would now like to know how exactly the series goes on and who dies all the way till the end so that if there are to be clever people, in the future, wanting to ruin the show for others I shall be able to ruin it for them as they have done for so many others.
