Pretty good episode, but the whole fake Daeron thing didn't work for me. The lack of reaction from the dragon should have been an obvious giveaway, and Daemon is far too smart to not force Daeron to bring his dragon south with him anyway. Maybe I am missing something, but this didn't add up to me.
I’m guessing Daemon figured Tessarion wouldn’t be a threat if she and Daeron were separated. If Daeron were allowed to ride her back to KL, who knows what disruption they might cause
