What to expect in Resident Alien season 4
The premiere episode told us everything that we knew would happen based on the trailer for the season. We knew that Harry would make it back to Earth, but that he wouldn’t have his alien abilities anymore. Now, we’ll need to find out what the Grey aliens did to him while he was imprisoned.
Meanwhile, Fake Harry is out there and could be a huge threat to the entire town. As more and more people learn that Harry hasn’t been Harry for a few months, there will be some concerns and questions raised.

The biggest question could be from Sheriff Mike, who has been seeing Fake Harry for his mental health. He’s working through seeing the alien, and he refuses to believe that there isn’t a “normal” reason to explain it. Will he eventually give in and accept that aliens are real so that he can protect the town?
As all that goes on, Ben and Kate are struggling. They want answers about the aliens and where their child is. We know that D’Arcy didn’t give the baby back knowing that the Greys would still come after the Hawthornes for the baby, and the end of the premiere confirmed the fears to be true. How long will it take for Kate to figure out the truth and accidentally tell the Greys?
Resident Alien airs on Fridays at 10/9c on Syfy and USA Network and airs on Peacock the following day.
