If you want to try to catch Mary in her small screen debut, "The Good Wife" is on CBS, not ABC. My bad. Her episode will be on Tuesday, February 9, at 10 p.m. She said she is in the court scene, behind the prosecution, three rows back in the middle.
I'll let you know when the "Ugly Betty" episode will air (sometime in March). Mary said she is right behind America Ferrara (the star of the show, Betty herself) in a theater scene, so she likely will be seen. Yay!
