You are so right! 10 episodes would have been perfect. As it is, it was hard to really care about Jon's decision: his and Dany's romance was never built up. We got to see Bronn only three times this season, and never doing anything really worthwhile. Dany's period of 'madness' was ended too abruptly, and let's face it, the fact that the Unsullied kept Jon a prisoner knowing without a doubt he killed their queen is unfathomable.
