You really think he'd be immature enough to write bad stuff on purpose out of pettiness against a few people on twitter? As the writer it's his responsability to be above that. He seems to have a ~idgaf about their opinions~ attitude, so that should include not being influenced by negative comments either.
And this almost feels like you wanting to put the blame on us if Jean is not portrayed well, which feels kinda shitty and manipulative.
