Exactly this. Simba was hoping he would dispute it. And hero didn't fall for it which really set him off. Simba creates fake accounts to send himself messages all the time. And by all the time I mean all the time. Plus, that writing style absolutely does not match with anything else Hero has written. Hero has never spoken with English that's that broken and lazy. Hero wanted a peaceful split, he did anything he could to return things to the way they used to be. Simba is lying through his teeth to smear a good person because he ate paint chips when he was a kid and he wants their guild members to leave Hero and join him. He's a power hungry nutcase.
