What do you mean "more"? This episode didn't give Bell a new ability. The stuff he used to blow most of the goliath up and reveal it's crystal was Argonaut, which was introduced a few episodes ago. And he needed a pretty long charge time, so I don't see it as broken or useful as you seem to think it is. It only worked here because other people were keeping the boss busy. And if you mean the Zeus reveal, I don't think it does much unless it suddenly gives him a new ability (and I think that since he obviously was Zeus grandson since the beggining, if he was gonna have an special skill for it, he would have it already)
Now, I gotta say I loved the Goliath fight. And this show in general was better than expected. Really good. Eagerly waiting for S2 (Even if it takes years)
