1. Survival of the Fittest

Complete story — includes the ending

The election results of the presidential race between Mellie Grant and Francisco Vargas are announced; Francisco Vargas won. Mellie initially refuses to accept defeat but eventually realizes she must call and concede. While making his acceptance speech, Frankie is assassinated. That leads David to tell Fitz that since Frankie and Cyrus weren't elected by electoral college, Cyrus isn't president, so Fitz must choose between Cyrus and Mellie. Olivia suspects Cyrus of murdering Frankie Vargas and has Huck, Quinn, and Charlie start looking for evidence. She visits the hospital and sees Cyrus looking disheveled, leading to her telling Fitz she no longer suspects Cyrus. He tells Cyrus that he is picking him to be president and announces it on TV. Quinn, Charlie, and Huck discover a voicemail from a Vargas campaign volunteer claiming that Cyrus killed Frankie. Olivia visits Cyrus and tells him she won't stop until she can prove he is guilty.
