In fact, on the chance that it was her husband intercepting your e-mail.

If he hadn't intercepted the email, then his BW shared it w/ him right away. They are trying to save his career. So, it would make sense that she shared it w/ him before she sent her reply to Gerk.

My best guess is that she already knew WW has been trying to contact OM. OM has probably been telling his BW about it. They are both trying to figure out how they can save his career.
