So anyone else feel Jon was way to useless this episode?
His scene with Viserion blocking the Tree Garden was also weird. It felt to me like he was buying time while trying to stay alive at the same time. His shout towards the dragon was also weird. The dragon hesitated for a split second. Actually after re-watching the clip while typing this Jon screams like 3-4 times.... It also sounds like he is screaming Go go go.
Possible he saw Arya gunning for the tree and opted to sacrifice himself to buy time + draw dragons attention?
Why did the dragon hesitate, why did it not just instantly bite or fireball Jon?
EDIT: Possibility of the dragon recognizing the true Targ Heir and hesitating?
