Grey's Anatomy, Season 13

Meredith:
[opening voice-over] There's an old story of a father who had two sons. When he knew a civil war was about to break out, he sent one son to fight for the North, and one to the South. He figured if he had sons on both sides, there'd be a better chance one would survive. Because when you fight a war at home, the casualties are your neighbors, your friends, your family, leaving you all alone.
