Yeah they really need Dany to grow this season. I am tired of her how she is portrayed. That scene with her running from the two dragons she chained up was stupid. Hell, chaining them up was stupid and out of character.
One of her titles is the Breaker Of Chains, not Chain Whom She Pleases. I don't get why they made her make such stupid mistakes for no reason. "Oh no the one dragon that has always given me trouble is giving me more trouble, I better chain up the two good dragons just in case" wtf? What kind of train of thought is that?
What kind of train of thought is assuming the other two dragons are "good" because they hadn't killed any innocents yet? It's a lot more likely they were just less developed than Drogon.
