One thing Marvel properties have in common is their fondness for hiding small details in plain sight. Sometimes, that’s an Easter egg. Others, that’s a connection the property will revisit. When Agents Of S.H.I.E.L.D. debuted on ABC, Marvel’s Head of Television Jeph Loeb liked to remind the audience, “it’s all connected.” This idea holds true within the show itself as well.
In season six of Agents of S.H.I.E.L.D., the first three episodes revisit a few items from season six. Agents visited the planet Kitson (mentioned to Kasius last year), Fitz farmed Xandarian snails (served at a dinner party last year), and Fitz was also threatened with a Vrellnexian (the roaches that overran Earth). It stands to reason we’ll see plenty more items in season six that call back to season five.
10 The Confederacy’s Sixth Alien
When the S.H.I.E.L.D. agents returned from the future, the series revealed that Hydra member General Hale already made contact with aliens. In fact, she communicated with a group called the Confederacy on a regular basis. She thought they were going to protect Earth from a larger threat.
Viewers learned the group was made of six alien races: Kree, Astrans, Rajaks, Kallusians, Remorath, and an unknown sixth race. The Confederacy is still on the tail of Daisy Johnson in season six. It’s only a matter of time before the audience meets more members and the mysterious sixth race is revealed.
9 Polly And Robin Survived The Season
When the team went to the future, the audience discovered the agents had actually raised the Inhuman Robin Hinton. Specifically, May raised her after her mother Polly didn’t make it to the Lighthouse with them.
When they went back to their present day, Robin, able to see the future and the present, still called May “mom.” Fitz sacrificed himself to make sure Polly got the chance to raise her daughter. That means there’s still a seer out there, who now likely has visions of multiple timelines in her head. Talking with her might prove useful.
8 Option 3: Alien Invasion
Though alien races weren’t introduced to the Marvel Cinematic Universe until the Thor movies; in the actual timeline, S.H.I.E.L.D. planned for an invasion way back in the 1970s. Season five revealed former Agent Stoner as the director of Project Reclamation at the Lighthouse.
As Coulson and May went through his computer program, they stopped a step short, picking a computer option for a nuclear war instead of an alien invasion. Option three in the menu planned for aliens. Though the Confederacy is searching for Daisy in space in season six, it’s entirely possible they, or the aliens they offered to protect Earth from, will make a return to the planet.
7 Astrans May Have Powers Too
One of the alien races that make up the Confederacy is the Astrans. The audience doesn’t know much about the MCU version of them because Talbot absorbed their representative with the gravitonium inside him. What the audience might not realize is that Astrans can manipulate metal in the comics.
In fact, following Talbot’s absorption of their representative, he then battled Mack and Elena in a scene very reminiscent of Magneto from Fox’s X-Men movies as he moved cars into their paths. It’s possible he was combining the Astran’s metal manipulation with the power of the gravitonium. If the race returns this season, we might find out.
6 The Cygnus Constellation
When the audience first met the Chronocom Enoch, he revealed himself as hailing from the Cygnus Constellation. In the comics, Cygnus is home of the Silver Surfer, but it’s unlikely we’ll see that particular character make an appearance. Instead, it’s more likely that, as the show expands, we might see a visit to Enoch’s home planet.
While Enoch was sent to Earth as an anthropologist, meant to study humans in their natural habitat, he wasn’t the only one. Chronocoms also aren’t all anthropologists. With more Chronocoms being introduced in the series, a visit home seems inevitable.
5 Deathlok Is S.H.I.E.L.D. Transport
While the audience will definitely remember Mike Peterson showing up to save Coulson’s life in the 100th episode of the show, they might not remember his actual purpose in the episode. Deathlok wasn’t there to fight bad guys. Instead, he was in charge of transport.
In fact, Deathlok was there solely because he was contacted to gather S.H.I.E.L.D. agents and bring them to the new base. He’s still technically a S.H.I.E.L.D. asset. The writers and producers like to bring him back when things get sticky, so perhaps the audience will see him fly in a few more characters this season.
4 The Multiverse Theory
When the writers brought Ghost Rider into the fold in season four, a lot more possibilities opened for the show. While Fitz was adamant that time could never be changed, season five showed fans that it could - at least in theory. Season five also brought with it Deke Shaw, who believed in the theory of multiple universes.
He pointed out that, despite the S.H.I.E.L.D. agents coming to the future, a reality existed where the world still quaked apart. With season six introducing a doppelganger of Phil Coulson, the show can’t just examine multiple planets, but possibly other universes as well.
3 Sound As A Time Travel Replacement
When season five began, it was with the vanishing of almost the entire S.H.I.E.L.D. team. In what seemed like the blink of an eye, six people vanished from a diner. In reality, the people in that diner lost two minutes of time thanks to the Chronocoms.
As revealed in a later episode, the Chronocoms used sound as a way to somehow stop time. Enoch had Fitz, Hunter, Polly, and Robin use earplugs to block the sound, so they remained unaffected while everyone around them lost thirty minutes of time. This technology hasn’t been used since, but it certainly still exists one season later.
2 Gegku Larva
When Fitz finally made his debut in season five, he masqueraded as a marauder. He even dined at one of Kasius’ dinner parties. One of the pieces of his disguise was an article pinned to his chest made of Gegku larva.
The Gegku is a comic book species, though they didn’t have larva on the page. Instead, they were reptilians from the planet Wilamean. With the series expanding further into space this season, a callback to where those Gegku larvae came from might be a fun nod for the viewers, if not necessarily a vital one.
1 Bobbi And Hunter Are Still Running
Season three saw Bobbi Morse and Lance Hunter become disavowed agents. They had to head out on their own with no further contact with the team. Hunter emerged in season five to help Fitz break out of a military facility but then disappeared into the wind again.
While S.H.I.E.L.D., and by extension Fitz, has likely been forgiven for its past crimes now that it’s up and running again, Bobbi and Hunter are a completely different story. The season has fewer episodes than those that preceded it, it would be nice for the fans if the duo could return to acknowledge Hunter’s part in helping save the world last season - and maybe finally get them off the Most Wanted list.
Is there something in season five of Agents Of S.H.I.E.L.D. that should make a return in season six?
