The smooth, charming and powerful patriarch of the Barbara clan, Don runs a multi-national corporation. "Barbie is shocked to find himself face-to-face with his father in an unforgettable turn of events," executive producer Neal Baer says. Could that mean that Don has been in the dome this whole time?
