The smoke monster was surrounded with electricity. Is that new? I can only remember it sounding like thunder but I do not remember seeing actually electricity. Maybe there is more than one smoke monster? One Ben controls and one roaming free on the island? I say this because why would they need the electric fence outside the barracks if he can control it? One answer I can think of is that he can not fully control Smokey. He can send him places but cannot control who it attacks. Thats why he told them to wait until it passed them. Also, Ben was not afraid of Smokey when one of the soldiers ran out of the woods and carry him away. So I'm assuming that the one who summonds him will not get hurt.
