>>30776050It's ont of those 'implied but only if you read into it' sorta things. Just like with N. What he went through is kinda glossed over in the game, but given the context clues and the unsetlling atmosphere of N's playroom, generally you put 2 and 2 together that it wasn't a happy childhood.
Similar situation. We have vauge hints that COULD mean he was hit by his dad, and so people dig and look for evidence to back it up. You can choose to interpert it either way, so people can have their deep, sad, abused character, but Gamefreak doesn't have to own up to it.
