Mei already knew who the Extra was before Izumi smashed her eye, though. She specifically tells Kouichi, when he asks her if she'd just seen it, that she saw it before she'd even heard the tape. She hadn't said anything because of how much that would devastate her friend, and once the Calamity was over that would've resolved itself...until they learned how to end the Calamity.
