>>26667948Actually In Saffron Gym there's a trainer who states Psychics "fear only Bugs and Ghosts", indicating that they did originally intend it to be the case. Also strategy guides published by Nintendo said to use Ghosts against Psychics.
But yeah I'll admit it does take a bit of a leap in logic to connect the two, but its just my interpretation of events cause it adds more to Giovanni's character and makes him way more interesting than just being a generic mafia boss guy without being too infeasible.
