Zane Talbot is the genetic son of Teodor Hájek and Eliška Sokol, and, in the eyes of the law, the child of Dr. Cameron Talbot and his wife, Melissa. Zane is also the unwitting cause of all the chaos surrounding the four adults, as he was swapped at birth by Dr. Talbot for his own son, because the Talbot's son had an incurable congenital condition, and the doctor wanted to spare his wife the heartache of losing a child.
