Definitely something to get dramatically mad over.
But no, despite the occasional Otto-like line, which even Daredevil thought was a joke, he still sounded like Peter and at the end of the day didn't try to take over the world like Otto normally would. And Carlie knew because Peter said something while trapped in Otto's body but she didn't believe him at first so please spare us the "Why did Carlie know?!" complaint, as if she's not allowed to participate as a character.
