I don't know if you're responding just to me, or just to the general interactions in the thread. But since you quoted me, I'll respond as if it's just me.
first off, switch to decaf. You seem awfully worked up over a tv show. I asked why you thought the waif got training in being blind because it didn't seem like some contrived part of Arya's training that was set up. It seemed like it happened because she screwed up.

I don't know who Peter Lafleur is.
It seems like there are definitely two camps of people when it comes to the Arya story arc: love it or hate it. I loved it, but that's my kind of story: some novice initiate enters into a clandestine, esoteric society and undergoes training. We watch as they get stripped of their ego and completely deconstructed as a human being, then they get rebuilt as a stone cold killing machine. I seriously would watch 4 hours of Uma Thruman training with Pai Mei from the Kill Bill Tarantino movies.
I get it if you didn't like it, and I can even understand reasons why you didn't. It's just personal taste. I dug it. We disagree. No hard feelings and slap it high?
these threads always kill me. Some people take shows like this and True Detective so seriously, and then some people are like my MIL, who will ask you plot questions when you come in the room about a movie she's been watching for an hour already. I still crack up when GPJ asks about Candy Crush in answer to an inane question.
