Season Five of Growing Pains begins as the Seaver family returns from the luxury cruise wherein the widowed mom of Jason Seaver (Alan Thicke) married her middle-aged beau Wally. Perhaps inspired by this event, Jason's son Mike has proposed to Julie Costello (Julie McCullough), the 20-year-old nanny of Mike's infant sister Chrissy. Dead set against their engagement, Mike's mom, Maggie, fires Julie and arranges for her own parents Ed (Gordon Jump) and Kate (Betty McGuire) to look after Chrissy--only to find out that her mom and dad are totally on Mike and Julie's side!
