Bobby and Cindy watch "Cinderella" on television, which starts a series of misunderstandings that convinces Bobby that his new "step-mother" doesn't love him. By the time we get to the last act, Bobby prepares to run away from home. Mike Brady has a nice, low key talk with him, assuring him that, though he's sorry to see him go, he feels that everyone should be able to find someplace where they'll be happier. Bobby picks up his suitcase and prepares to leave. At the bottom of the staircase Carol is waiting, with her own suitcase.
"I heard you were leaving," she says.
"Yeah."
"Well, why don't you let me take the big suitcase and you carry mine."
Bobby looks stunned. "Where are you going?"
"Well," Carol explains, "I'm not going to let you go away alone. That's a big world out there. I'm going with you."

I've loved Florence H. ever since. RIP.
