 In 1983, a young man named Gordon goes through a transformation, losing his eyes and gaining the ability to teleport. He is scared of what has happened to him, but is comforted by Jiaying, a young-appearing woman who herself is special, having not aged in decades. Jiaying has guided many young people through their own transformations, knowing that without guidance, they would be lost. This is a situation that her daughter, S.H.I.E.L.D. agent Skye, is now unknowingly in, having gained earthquake abilities in an alien city while her friend, Agent Antoine Triplett, died. In quarantine due to the potential effects of the city on her, Skye feels responsible for everything bad that has happened. Director Phil Coulson, however, blames Hydra for their misfortune, and devises a plan to get revenge against the rival organization.
 Hydra themselves feel like they have been heavily defeated since Coulson killed their North American commander, Daniel Whitehall. In a meeting with several high level Hydra operatives, Dr. List, a representative of Hydra's leader Wolfgang von Strucker, explains that whoever can take out S.H.I.E.L.D. for good will get Whitehall's position, setting up a power struggle between the other members. In the alien city, Jemma Simmons is preparing to flood it to prevent anyone else entering it, but not before Raina, who was changed in the temple like Skye, crawls out of the rubble left by an earthquake and kills several agents. Raina's appearance is now monstrous – she is covered in thorns and spikes. Escaping the tunnels, Raina tracks down Skye's father, Cal, and demands he fix her. He reminds her that she got what she wanted, and tells her that if she can not live with who she has become, then she should not.
 Coulson makes a deal with Brigadier General Glenn Talbot to give him Whitehall's former second-in-command, Sunil Bakshi, in exchange for assistance with taking down Hydra's forces. En route to the hand over, Coulson and Agent Melinda May are attacked by Hydra forces. After a fire fight, Coulson, May, and all but one Hydra operative are dead. Bakshi escapes with the operative, who is actually S.H.I.E.L.D. ally Lance Hunter: The attack was a ruse. Bakshi leads Hunter to the house of one of the top Hydra members, Octavian Bloom. Bloom and Bakshi believe that the other top members are targeting them, and send out an order to have them killed, along with Hunter. Hunter, with the help of Agent Bobbi Morse, fights his way into the house, kills Bloom, and takes Bakshi back into custody, to finally be delivered to Talbot. Now, all of Hydra's top level operatives in North America are dead.
 Simmons feels that Raina may be the first victim of an epidemic, and should be put down. Leo Fitz deduces that Skye caused the earthquake in the alien city, and so herself has been altered just like Raina. Hearing what Simmons wants to do to Raina, Fitz decides to hide the truth from the rest of the team. Skye believes that there is something wrong with her, but Fitz tells her that she is just different now, and there is nothing wrong with that, and she is released from quarantine. Raina, unable to come to terms with who she is, takes Cal's advice and attempts suicide. She is prevented by S.H.I.E.L.D. agents, who try to take her in, but before anything happens, a much older Gordon appears, and teleports away with her.
 In an end tag, a model car that Agent Alphonso "Mack" Mackenzie built for Coulson scans the latter's office, discovering the "toolbox" that former S.H.I.E.L.D. director Nick Fury gave to Coulson. Mack secretly reports this discovery to Morse while making food, then they join in with the rest of the team having drinks and sharing memories of Triplett.

 Starting with this episode, Marvel once again ran the "Art of..." initiative, in which an image was released the Thursday before the episode aired, depicting a first look at a key event from the upcoming episode, with the season's title being "The Art of Evolution". The different artists were once again chosen to create the teaser posters, based on their previous work and how it connected to the themes and emotion of the intended episode. The poster for "Aftershocks" was created by Gabriele Dell'Otto, the co-creator of Daisy Johnson, and depicts Skye twice, as she is transforming from the Terrigen Mist and as the person dealing with her powers, as well as a transformed Raina, Coulson and the S.H.I.E.L.D. logo in the background. Dell'Otto was chosen specifically because of his relationship to the character.
 The episode began streaming on Netflix on June 11, 2015, and was released along with the rest of the second season on September 18, 2015, on Blu-ray and DVD.
 In the United States the episode received a 1.6/5 percent share among adults between the ages of 18 and 49, meaning that it was seen by 1.6 percent of all households, and 5 percent of all of those watching television at the time of the broadcast. It was watched by 4.48 million viewers.
