It was not so much a "shocking death" that ABC had promoted earlier about "Brothers & Sisters" last night's episode. However, the show is prepared for a larger scheme that involves an arrival and departure.
Nora is asking the favor of the whole family to welcome the love-child of William, Ryan Lafferty who is played by Luke Grimes. Ryan gets a bit too close too fast for anyone's good. Meanwhile, the episode's title "Taking Sides" explains on the two sides built in the middle of the family. Saul and Sarah go to extremes to hide Tommy's legal troubles from Nora, while others try to expose it.
Also, even in the wake of a life threatening medical crisis and the excitement surrounding the birth of his son, Robert remains steadfast in his drive to run for governor, despite the damage that it may do to his marriage.
"Taking Sides" is aired March 8. This would provide the beginning of the plot to let Balthazar Getty who plays Tommy go.
