ABC originally planned for S.H.I.E.L.D. season 5 to enjoy an uninterrupted run after the network pushed back its premiere from its usual fall position to December 1st, 2017. This was so that ABC could focus on its 8-episode event series, Marvel's Inhumans, which was intended to carry on the Marvel brand but was instead a critical and ratings disappointment. However, once S.H.I.E.L.D. returns to the air after the Olympics, it is expected the series will resume the rest of its season uninterrupted.
In season 5, Agents of S.H.I.E.L.D. experienced a creative renaissance coming off its much-lauded season 4. The team led by Agent Phil Coulson (Clark Gregg) found themselves unwillingly whisked away to a post-apocalyptic future where the Earth had been destroyed - blamed on the Inhuman powers of Agent Daisy "Quake" Johnson (Chloe Bennet), dubbed "The Destroyer of Worlds" - and the remains of the human race had been conquered by the Kree. The series went even deeper into the realms trippy sci-fi by revealing that the Agents were trapped in a causality loop where even if they managed to find a way to time travel back to 2018, they would still fail to prevent Earth's destruction, no matter how many attempts they make, each of which could create an equally tragic timeline.
Nevertheless, our heroes persisted in trying to save the world and make it back to 2018. Forging new alliances on board the space station called the Lighthouse - including a young Inhuman named Flint (Coy Stewart) - Coulson and his team fought a revolution to liberate humanity from the Kree, eventually bringing down the regime commanded by Kasius (Dominic Rains). With the help of Flint, whose Inhuman powers of geokinesis rebuilt the Kree Monolith that brought them to the future, the Agents saved the Lighthouse and then successfully jumped back to our present day.
When Agents of S.H.I.E.L.D. comes roaring back in March, they will immediately find themselves hunted as the 'World's Most Wanted' fugitives. Many loose ends from the events of season 4 must be reckoned with, including the shooting of General Glenn Talbot (Adrian Pasdar) by a Life Model Decoy of Daisy Johnson. All of this trouble is compounded by S.H.I.E.L.D.'s disappearance and the prison break of Leopold Fitz (Iain De Caestecker) by former Agent Lance Hunter (Nick Blood) so that Fitz could join his friends in the future. There's also the mystery of just what Ruby, a new character played by Dove Cameron, has in store for our time-tossed secret agents. Finally, a prophecy that Phil Coulson himself might be the cause of the Earth's destruction may force S.H.I.E.L.D. to choose between saving the world and saving their leader's life.
Before Kasius' met his end, he also foretold that his mysterious unnamed father, who coveted the Earth, may soon mount an invasion of our world that only S.H.I.E.L.D. can fight against. Before season 5 is over, the Kree may once again rear their blue heads, this time in 2018. Indeed, we may also learn at last how the Earth was destroyed - and if S.H.I.E.L.D. can save it. No doubt, Marvel's Agents of S.H.I.E.L.D. will cement its status as the best reviewed Marvel TV series by the time season 5 concludes.
Marvel's Agents of S.H.I.E.L.D. returns on Friday, March 2nd @ 9 pm on ABC.
