Just after Pablo had finished talking with Draxus, he found himself around Darkness.
He believed he was teleported somewhere. But upon closer inspection, he found that he didn't have his Colt on his hand and he was dry.
He was dripping with water in the Crucible and it wasn't possible to get dry this fast. Also, he tried to summon Colt but nothing arrived. So Pablo reached a conclusion.
His mind was trapped.
Corrosive had used his Ego and it worked.
So I am inside some kind of illusion and my body must be standing still outside. Did he use this same thing in Boulder too? No wonder he managed to bite his shoulder. But then it also means that Boulder was able to break free as well. All by himself. Otherwise, the Cannibal king surely wouldn't have stopped just on the shoulder. But there should be something more to this. This darkness can't be the only thing here.
