People say that she shouldnt have admitted to being Omni Mans wife but honestly she was just overcome with grief and guilt after hearing him reveal who he was.

The best option was to reveal herself at that moment because if she held anything back she would be more guilty pretending she isnt directly connected to his own tragedy. And it would be a secret that he would feel even more angry about.

He shouldnt have revealed who he was and they couldve saved themselves the trouble.
