They're going to end it before Stannis proves why he's the best fucking king of all. I just know it. Just like the Joffrey cockblock last season. I doubt even Tywin conclusion happens. They'll spend 40 minutes of an episode focusing on a cripple and a tree and a bunch of nothing happening to Dany, Cersei, and Jaime.
I'm saying it out of superstition hoping that it'll not happen. Last time I made a prediction about an episode I ended up being completely wrong. I'm just praying, please dear baby Stranger jebus give me the rightful conclusion (at this point) to the Stannis arc.
As an aside, all my friends hate me because Stannis is by a wide margin my favorite character, in the books and in the show, followed as a close second and third by Bronn and Jorah. He completely lacks a decent personality, mostly acts like a dick in every encounter, and is just generally unlikeable, according to almost everyone I talk to. But I still maintain he's one of the only true decent and honorable people in the whole thing. He's the one who really uncovered the incest thing and even gave all the credit to Ned Stark, he pwned the Greyjoy fleet and held Storm's End against a massive army with barely anyone at his disposal, he's the only one who actually dispenses justice according to the law of the lands, he largely disregards status and birth in rewarding his subjects, and is arguably the most accomplished military commander of any character in the entire series of novels. His one failing is the fact that he's a dick without a personality, and a dick being manipulated by a hot fire priestess who practices blood magic. But the hot fire priestess practicing blood magic burning people alive produces results in a war against fuckers borne of incest disregarding every law of the land. Plus, he's pretty much irreligious and is using the fire god solely as a means to an end to acquire what is his by the currently established laws of Westeros.
Sorry, I'm proselytizing, but I'm gay for Stannis, and I want him to get his fucking spotlight before this season is over, rather than half an episode being consumed by conversations about beetles.
