An attempt to keep a 17-year-old JFK from being assassinated by Rittenhouse goes awry, and Wyatt and Rufus are forced to bring him with them to 2018, leaving Flynn behind to fight it out with the sleeper agents. The future president flees the bunker and finds out he's in the future, as well as his own fate and that of his family. Jessica finds out about Wyatt and Lucy and wants to leave to give them a chance, only for Lucy to convince her to stay and give Wyatt a chance. Agent Christopher is kidnapped by Carol, who tries to convince her to keep Lucy from going on any more missions in order to keep her safe.
- Drowning My Sorrows: JFK, after learning about the "Kennedy curse". At the end of the episode, Flynn wordlessly hands Lucy a beer after overhearing their conversation about Jessica, knowing she needs a pick-me-up.
- Evil Teacher: Kennedy's teacher turns out to be a Rittenhouse sleeper agent and tries to kill him. Luckily, Flynn shows up just in time.
- The Future Is Shocking: Kennedy's reaction to 2018. This also applies when he gets access to Wikipedia and learns about himself and the "Kennedy curse". Oh, and World War II.
- Gone to the Future: Averted in Kennedy's case. The young Kennedy being taken from 1934 and brought forward in time to 2018 doesn't lead to him being wiped from the timeline. Jia takes this to mean that they will successfully return him to his own time...provided that he isn't killed by Rittenhouse first.
- In Spite of a Nail: Despite learning about his own assassination, JFK is still killed, but for some reason it happens in Austin instead.
- I Want My Beloved to Be Happy: Lucy tells Jiya this almost word-for-word. She even convinces Jessica to stay.
- Love Triangle: Jessica catches on about Wyatt and Lucy. She decides that Wyatt would be happier with Lucy, but Lucy tells her everything Wyatt has done to try to get her back, convincing her to give him another chance.
- Make Wrong What Once Went Right: Keynes wants JFK killed well before he ever gets into politics, so that someone more in line with the direction Rittenhouse is going becomes president, such as Nixon.
- Outdated Outfit: Kennedy's 1934 school suit looks decidedly dated in 2018, and the college students he meets up with give him weird looks.
- Ripple Effect Indicator: The coin with Kennedy's image engraved on it. The image starts to morph into Nixon's when it seems like Emma is about to successfully kill the young JFK.
- Secret Keeper: The college student Kayla, who helps Kennedy and finally realizes that he is who he says he is.
- Shame If Something Happened: Carol threatens Christopher's children if anything happens to Lucy.
- Surprise Pregnancy: Apparently, Carol was telling Lucy the truth that she wasn't planned (even though her relationship with Cahill probably was). In fact, Carol planned to give her up for adoption in order to keep her away from Rittenhouse.
- Technology Marches On: Kennedy is both shocked and amazed at the level of technology in 2018, including cell phones and tablets. He asks a gas station attendant where he can find a payphone. The confused guy tells him to try a museum and hands him his smartphone to make a call, causing Kennedy to look blankly at the glass brick. The number he tells the attendant also includes a routing area, something that is no longer in use.
- Temporal Mutability: Jiya and Rufus argue about this. Jiya now thinks that some higher power has gifted her precognition, while Rufus is a staunch atheist. Later on, Rufus warns Kennedy about his assassination in Dallas. Upon returning, he is saddened to learn that Kennedy was still assassinated the same year, but in Austin this time.
- Timeshifted Actor: This is the second time JFK shows up on the show. In "Atomic City", the 40-something President was played by Scott Bailey. This time, the 17-year-old JFK is played by Grant Jordan.
