After it is revealed to Misty that Tabitha is still alive, she learns that Tabitha smokes, flirts with boys, and is not as loving, sweet, or innocent a child as she'd previously thought. Grace is the mother of Peter and ``Granmy'' to Tabitha. Misty is often annoyed by her, whether it's the way she wastes Misty's money, or the way she's influencing Tabitha.
