Resident Alien's Grey Aliens, certain figures among the townsfolk of Patience, Colorado could be handled very differently by the writers.

Tudyk has led Resident Alien since the show began in 2021. Although Resident Alien season 4 begins, it's highly likely that he will be playing the Mantid that stole his identity in the season 3 finale, "Homecoming." Villains in the show tend only to be seen through the eyes of the heroes. So, Resident Alien may step away from the Mantid and bring back a rarely-used storytelling trick.

Harry Being Sidelined In Resident Alien Season 4 Means Other Characters Can Narrate Episodes

It wouldn't make sense for Tudyk's character to retain narrating duties from his jail cell

One of Tudyk's primary responsibilities as Resident Alien's star is to narrate the story in real time. Of course, this inner monologue can only be heard by the audience rather than by its characters, but it helps add additional context to many of Harry's actions that may seem strange or unexpected. He has done this in every episode so far, but with him held captive aboard the Greys' Star Wars-inspired moon ship in the season 3 finale, he won't really have very much to comment on until he escapes. So, Resident Alien season 4 can share this role around.

Pretty much every main member of the Resident Alien cast is made aware of the existence of extraterrestrial life by the end of season 3. So, they will likely be coming together to fight the Greys in the run of episodes. Because many of them will be processing new emotions caused by their respective alien encounters, they may not want to say all their overwhelming thoughts out loud. Therefore, allowing each of them to contribute as the show's narrator would be a great way of getting a peek into their heads.

Resident Alien Already Proved Different Narrators Can Work

Ben has already briefly taken over as Resident Alien's narrator

It may seem like a big risk to replace Harry as Resident Alien's narrator, even temporarily. Thankfully, the show has already experimented with this in season 3's penultimate episode, "Here Comes My Baby." The installment has a scene where Mayor Ben Hawthorne (Levi Fiehler) is spying very badly on Sheriff Mike Thompson (Corey Reynolds) and Deputy Liv Baker (Elizabeth Bowden). Hearing Ben's thoughts as he hilariously fails to remain hidden is hilarious, so Resident Alien season 4 would be wise to repeat this creative choice with various characters.
