I can't read any of the posts on here

On here it has been pretty cool. Everyone that has posted them has alerted us in the title line and everything else in postings has had the spoiler [spoiler]"like this"[/spoiler] tag.
Even elsewhere I haven't seen anything that hasn't warned it was a spoiler.

But all bets are off after it airs.
Don't go anywhere online until you see the episode

At the end, the Night King is the bad guy. (And you didn't want spoilers, too bad, muaaahaaahhaaahh!!)

I suggest getting caught up.

Episode 6 airs in a couple days, and you will want to be here discussing the ending with the rest of us.
