Again,

If you didn't think that was a possibility from everything that had been written to this point, then I don't know what to say.
For me anyway, I dislike episodic tv in general, and I'm thinking I might just be disinclined towards passive forms of entertainment as an umbrella group at this point in my life. That's probably why I like Sherlock so damn much- it's fun to try to figure out what's going on before the reveal.
I treat this series the same way. I'm trying to figure out what's going on before fatty tells us, or the show shows us. So, I'd pretty much figured out that was a likely thing for the others, tbh.
I really think that all of y'all book purists might be better off fucking off and not watching the show anymore. If there's going to be an epic clash between the forces of life and death, light and darkness at some point down the road, then they have to define the enemy better. That's just part of visual storytelling. Sorry if it bunches all of y'alls panties, but I'd either get used to it or quit watching.
