The wait is finally over, but it’s a bittersweet moment for fans of the cosmos’s most conflicted alien. “Resident Alien” is back for its fourth and final season, promising a climactic conclusion to the saga of Harry Vanderspeigle. After a jaw-dropping Season 3 finale that left our favorite extraterrestrial in a seriously precarious position, this last chapter is set to resolve the fates of everyone in Patience, Colorado. The show has made a big move from Syfy to its new home on USA Network, and it’s gearing up to deliver the definitive ending we’ve all been waiting for. So, grab your favorite pizza (with no olives, of course) and let’s dive into everything you need to know about the final season of “Resident Alien.”
This season picks up immediately after the shocking events of the last finale. The real Harry (the incomparable Alan Tudyk) is trapped in a prison on the Grey Moonbase, while a shapeshifting Mantid has taken over his body and is now masquerading as him back on Earth. This impostor has everyone, including Asta (Sara Tomko) and D’arcy (Alice Wetterlund), completely fooled, creating one of the most suspenseful situations the series has ever seen. The central conflict of the season will be Harry’s desperate attempt to escape his lunar prison and return to Earth for a final showdown with the formidable Mantid. Will he be able to save the town and the planet he has begrudgingly come to care for?
What Can We Expect from the Final Season’s Plot?
The creators have confirmed that since they knew this would be the last season, they’ve crafted a story that ties up all the loose ends. There will be no frustrating cliffhangers here. We’ll see Sheriff Mike (Corey Reynolds) and Deputy Liv (Elizabeth Bowen) get closer to solving the mysterious deaths in Patience, which Mike is starting to believe are not of human origin. Ben (Levi Fiehler) and Kate (Meredith Garretson) are also on a desperate search for answers after their own alien encounters. And a major storyline will revolve around the return of Terry O’Quinn as Peter Bach, the alien-tracking podcaster, now in a resurrected cyborg form, who plays a crucial role in the fight to save his son and Liv.
Are There Any New Faces in Patience?
This season introduces a significant new character who promises to shake up Harry’s world like never before. Emmy-nominee Stephen Root joins the cast as Ed, Harry’s father. His arrival is set to dredge up a complicated past and may push Harry to confront the “different ethics systems” between his species and the humans he has grown to protect. This dynamic is sure to add another layer of dark humor and emotional depth to Harry’s final journey.
