Last night on Brothers and Sisters, lil Elizabeth needed a liver transplant from her father. But since she was conceived with the help of her uncle's sperm, it had to be Kevin or Justin's organ donation. The Walkers never knew which of Tommy's brothers was the biological father of his daughter until it was revealed in the wake of this crisis. Tommy was understandably disturbed by the process (and the fact that he had to rely on his brother, Kevin, to help his child), would you be?
