It looks like Joe has made his move. We’re definitely seeing the beginnings of another conflict between the personalities like in issue #376. However, on second thought, what if that’s not Joe we’re seeing but Brian Banner instead? He has been seen since issue 24, and he also makes the same expression on his face when he’s around. I think about it, that would explain why Bruce had that mustache in issue 18, and why he was asking joe for help at the end of #24. Perhaps in order for TOBA’s ultimate plan to be realized, Bruce and Hulk need to be physically separated again, with it taking control of Hulk’s body and Brain having control of Bruce’s body as reward for his obedience and revenge for Bruce killing him.
