Though Jeff may not have agreed with Mona’s reasoning, he wanted his marriage to work.

Mona knew this plot had Phoebe’s signature all over it. Myrtle pleaded with Mona not to tell Kitty the truth. Mona realized Myrtle really loved Kitty. She agreed that she would let Myrtle break the truth to Kitty in the way she saw fit.

She noted the same birthmark. Kendall admitted she came to Pine Valley in search of her mother. The Kane women reunited in time for Erica’s marriage to Dimitri Marick.

Luckily, she made it through the operation safely, and her cancer went into remission.
