Christie (Tracy Stratford) is the little girl who loves her new doll, Talky Tina, in the Twilight Zone episode, Living Doll. But the doll is literally alive--and she hates Christie's stepfather.The doll seems to be a supernatural manifestation of Christie's resentment for a stepfather who makes a feeble effort or two to be a good daddy--but is generally mean and hateful. Christie and Tina are both diminutives for Christina.
