My take on episode 4:
Battle season was one of the best GOT has so far, but there was quite a few unnecessary damage. Why she burnt all the grains? - She has to feed her Army, Grains are as important as Gold, specially for her, when she has such a big Army and Dragons...I would have liked the scene better, if they saved the grains and killed the soldiers, that would have been smarter move on her...Cersi got the Gold and she got the grains...
Bran Story line is interesting, they made a point that in tree cave, when last three eye raven was dieing, he uploaded lot of data into Bran's brain(that's mouth full), the side effect of that event was that Bran is no more Bran...His role in the War of Dawn, got to be more than spying in time and space...
Although it's annoying to see Dany keep asking for bending the knee, but its still politics not charity, they don't sign a simple doc without give and take, how she could go to a whole new war without full support? - But they are coming close to gather, quite literally

- I can see a nude scene coming later this season
Its also clear that Stark children are not scheming or plotting against each other, non of them are hungry for throne. There does not seems to be any twist in their reunion. They have different personality, but still love and trust each other for most part. They will confront each other on tactics moving forward but largely will be going in same direction as guided by Bran and Jon, I don't see any major twist...Little finger has very little time left, he was shocked at Bran's one liner, "Chaos is a ladder"(that was brilliant by show runners), which he said to Varys himself back in season 1...Indicated to audience that Bran has gone through Little finger's entire life, Bran knows his role in various events regarding his family...
Other than Cersi, everybody is shaping up to be on the good side. I am trying to see, where is the twist?? - Both Jammie and Cersi are main character, I don't see them dying this season...Jammie may not die at all
Name suggests that big events in Next Episode will be Jon's parenthood reveal to the masses, but that's not the only thing, he has blood of Dragon as well, Otherwise why would you use such an obvious phrase as name of the Episode? - Dragon shot, was also hinting at the relationship of Jon with Dragons...We may see death of Little finger as well...
