God, this power and 'fight' is fuuuucking with me. If this is all the source of Tooru then:
Mitsuba isn't pursuing Head Doctor / Calamity (Calling it Head Doctor after the Snoop Dogg song, to make it easier). She is just seeing it as it is coming towards her, appearing on devices, in real life, and in reflections. Does just SEEING it trigger Head Doctor's calamity? Can it trigger without
Can Head Doctor change appearance? Because we saw Satoru Akefu giving a press conference about Rocacaca. Was that unreliable narrator and it was actually Tooru on stage? Did Tooru make Head Doctor take the appearance of Satoru because he successfully lured the crew into chasing Satoru, which is a trigger for the power? WHAT STAND IS THIS?
Is this Head Doctor before taking on an appearance, if it can change appearance?
If Head Doctor is a stand, is Satoru Akefu completely uninvolved with the scheme? Or is he in on it and a rock human too?
If Head Doctor is a stand and it wasn't Satoru Akefu back in the Poor Tom arc, WHO WAS DRIVING THE VAN? CAN STANDS DRIVE CARS? WHERE DID IT GET ITS DRIVERS LICENSE?
