I've always had a little theory in the back of my head. Since Kay became a Catholic, and agreed to raise the kids Catholic, is it possible that she never had an abortion? I know that it's strictly my imagination here at work, but Kay was horribly hurt by Michael's betrayal. She married him because he promised her legitimacy, that he wouldn't be like the rest of his family. Could she have had a miscarriage, as Tom told Michael, but lied to Michael about it in order to hurt him? To deliver a lethal blow to their marriage? To tell him something she knew that he could never forgive?

Since Kay was kept at the Tahoe estate as a virtual prisoner, not even allowed to go shopping, where would she have obtained an abortion, which was illegal at the time? How would she have done it under the watchful eyes of the bodyguards and Tom Hagen?

Just something that's always sort of nagged at the edges of my mind.
