Conner forget his powers yet again, but that is common with Kryptonian (or close to) protagonists. No reason to attack Zombie Deathstroke the way he did. Of course, he had to fail for Robin (Dick, Nightwing, etc.) to duke it out with a super opponent. That was the problem with the serious animated show before GO! It was always Robin and his Bo.
Still like the show, keep Jinx around. Love her.
