Harry and Heather’s future hits a painful wall in Resident Alien Season 4 Episode 4

After everything Harry and Heather have been through, you'd think their reunion would be happy. But Resident Alien never makes things that easy. With Harry no longer an alien and Heather still very much one, their connection gets caught in a strange and heartbreaking place.

Heather shows up ready to commit, even proposing marriage, unaware that Harry's alien form is gone for good. And while he tries to fake it at first, he finally tells her the truth. Surprisingly, she doesn't push him away. Instead, she accepts him and agrees to live in her human form just to be with him.

But love isn't just about two people, and Resident Alien Season 4 makes that very clear. It's about the world around them, too. That world turns against them when Heather's father shows up and makes his feelings about humans very clear. In the end, Harry sees what's coming. If Heather chooses him, she'll lose her family, and he can't ask that of her.

So they part ways, both heartbroken but understanding why they have to walk away. It's the most human thing Harry has ever done.

D’Arcy’s lie drives a wedge that might not heal

Episode 4 of Resident Alien doesn't just focus on Harry; it also explores the lives of other characters. D'Arcy finds herself backed into a corner as well. Kate begins to recall parts of the past, especially the ship and her missing baby.

Suspicion increases, and D'Arcy knows she's running out of time. When Ben pushes her for the truth, she decides to lie rather than risk the safety of the child she's protecting. It's a difficult choice, and it weighs heavily on her.

Alice Wetterlund delivers a gut-wrenching performance here. You can see the toll of the lie on D'Arcy's face, especially because she's not just lying to anyone-she's lying to her oldest friend. This choice isolates her further, but it also shows how far she'll go to keep a promise.

There's a subtle sense of relief when she calls Judy afterward, maybe hoping to feel less alone amid the fallout. Judy's easygoing weirdness adds levity, but it's clear D'Arcy's struggle is only just beginning. She's carrying a weight that gets heavier with every scene in Resident Alien.

Secrets test Sheriff Mike’s honesty and Liv’s curiosity

The cracks continue to spread through Patience, and Sheriff Mike finally reaches his breaking point in this episode of Resident Alien. He confesses to Lena that aliens are real. It's a huge moment for Mike, especially since Lena has no reason to believe him.

Her reaction is understandably skeptical, and their tension spills over during their awkward ride home. But in the end, they manage to make things okay. When Mike says "I love you," it feels like he has earned it, as if he's finally growing out of his need to control everything. Meanwhile, Liv feels left out.

Everyone else seems to be encountering aliens, except her. So, she takes matters into her own hands by setting up cameras in the forest where Mike saw the Mantid.

Of course, Heather's already handled that problem, but Liv doesn’t know about it. Her determination is both funny and a little sad, if you think about it. It's a good reminder of how many people in this town are chasing truths they don't fully understand.

Then there's Kate, who gets a chilling sign that her paranoia isn't just in her head when a young Girl's Guide slips her a tracker. The Greys are still watching. Resident Alien Season 4 Episode 4 gradually rewrites the story through difficult and emotional choices.

Harry's goodbye, D'Arcy's lie, and Mike's confession all carry significant weight that will echo throughout Season 4. With each character forced to choose between truth and protection, the episode ends with one thing clear: in Patience, nobody's secret is safe for long.
