You may recall that Marg left the original series during season 12 (which was three seasons before it ended).

She said that she needed to take a step back after I had played the role for so many years and it had become part of my identity.

This was stated during the Television Critics Association's virtual summer press tour.

Margadded, "having that view of being away and then coming back in a big manner as this, I actually missed her."

She was a dear friend and I miss her passion. I also missed her swagger and spunk. She stated that she would like to be sure she was saying yes before returning.

"Only because it was important to me that Catherine would return to this job," she said.
