We've already seen a few glimpses of how Rebecca is dealing with being a single parent after Jack's death, and in season four, Moore is excited to explore how she adjusts to being an empty nester when the Big Three go off to college. "The kids are about to graduate from high school . . . I'm sure that is a tremendously lonely moment, becoming sort of this empty nester especially after being a widow . . . I'm curious to see what she does with her life and interested to see if she goes back to the music world, if that's something she finds solace in," she told Good Housekeeping. "I want her to start picking up the pieces of her life and find some joy again. I'm looking forward to seeing how long that takes. What were those steps in between to get where she is with Miguel?"
