Very spoilery, so don't read either if haven't read books...
Spoliery reply don't look...... blah blah
Blah blah book spoiler, (technically we are discussing the show because it's how we expect the books to fit them).
If you haven't got the jist of it by now you're not trying hard enough.
Don't click it, just don't...
EDIT: Just realised it may contain spoilers for episodes 3 or 4 too. They've all merged into one for me.
