"I can't lose to him"
Ok, so in the Trivia it says that Junpei's in-battle Persona-summoning comment "I can't lose to him" is referring to the male protagonist. Is this actually true? When people say that sort of thing, they're usually referring to their opponent, and Junpei is never the protagonist's opponent. I'd be more inclined to think that Junpei is referring to whatever Shadow he is fighting (and just regarding all Shadows as male) than the protagonist.
