Zach Fuller. If you watched the first few episodes of Ginny and Georgia, you probably wanted to reach through the screen and give the kid a time-out. He was the classic, entitled "mini-me" of his mother, Cynthia Fuller. He spent most of season one making Austin Miller’s life a living hell.
But then something shifted.
The show did what it does best: it peeled back the layers of a secondary character and showed us the rotting fruit underneath the family tree. Zach isn't just a random kid in a sweater vest. He’s a deeply lonely boy watching his father fade away in a literal glass box of a bedroom.
Who Is Zach Fuller?
Zach is played by Connor Laidman. In the beginning, he’s defined entirely by his mother’s rivalry with Georgia Miller. Cynthia is Wellsbury’s resident Type-A realtor, and Zach is her weapon of choice. He bullies Austin. He’s mean. He’s basically that kid on the playground everyone avoids because his mom will sue you if you look at him wrong.
Then we find out about Tom.
Zach’s father, Tom Fuller, is in a coma for a huge chunk of the series. He’s suffering from a terminal illness that the show never explicitly names—though fans and medical professionals online often speculate it’s something like ALS or a terminal brain disease. Zach isn't just being a jerk for the sake of it; he’s a child who doesn't know how to process the fact that his dad is a ghost in his own house.
From Enemies to "Hide and Seek" Partners
The turn in Zach and Austin’s relationship is one of the most grounded parts of the show. Kids are weird. They can be mortal enemies on Monday and best friends on Tuesday because they both like the same video game.
For Zach and Austin, it was more than that. It was shared trauma.
Austin, despite having his own issues (like, you know, stabbing Zach with a pencil in season one), is a remarkably empathetic kid. When he realizes why Zach is acting out, he stops fighting back and starts showing up. By season two, they aren't just classmates; they’re brothers-in-arms.
They spend their time playing in the "magic" woods or hiding in closets. This leads to the most traumatic moment in the series for Austin: witnessing his mother, Georgia, "mercy kill" Zach’s father while they were supposed to be playing hide and seek.
The "Aging" Controversy
If you’ve been on TikTok or Reddit lately, you’ve seen the memes. People are losing it over how much Zach and Austin have grown.
Ginny and Georgia season 3 picks up right where season 2 left off. Literally the same day. But in real life, years passed between filming. Connor Laidman and Diesel La Torraca (Austin) hit puberty like a freight train.
Suddenly, these "nine-year-olds" are towering over their mothers. Zach is practically a man in a middle-schooler’s wardrobe. It’s a bit jarring to see them sitting in a tiny elementary school classroom when they clearly need to be heading to a high school party.
The production didn't recast them, which was a bold choice. It keeps the emotional continuity, even if the visual continuity is... well, it’s a mess. Honestly, you just have to suspend your disbelief and pretend they aren't six feet tall.
Why Zach Matters for Season 4
The fallout of Tom Fuller’s death is going to be massive for Zach. He thinks his dad died of natural causes. He has no idea that Austin’s mom was standing over the bed.
This sets up a ticking time bomb.
If Zach finds out what Georgia did, his friendship with Austin is toast. More importantly, it turns Zach from a background character into a central figure in Georgia’s potential downfall. He is the living reminder of the "good" deed Georgia thinks she did, which was actually a horrific crime.
What we know about Zach's future:
- He’s still grieving, and season 3 showed him struggling to navigate a home without his father.
- The bond with Austin is strained because Austin is carrying a secret that would destroy Zach’s world.
- Cynthia’s downward spiral and her "relationship" with Joe has definitely impacted Zach’s stability at home.
Takeaways for the Fans
If you're keeping track of the Wellsbury drama, don't sleep on the kids' storylines. While Ginny and Marcus are busy being moody, Zach and Austin are dealing with actual life-and-death stakes.
Watch for these details in your rewatch: Look at how Zach’s behavior changes the second he’s away from his mother. He drops the "bully" act almost instantly when he's with Austin. It’s a classic case of a kid performing for an adult’s expectations.
If you want to stay ahead of the curve for the next season, pay attention to the scenes in the Fuller household. The tension there is building, and Zach is right in the middle of it.
Keep an eye on the official Netflix social channels for season 4 updates, but expect a time skip. The producers almost have to do one now, if only to explain why Zach and Austin look like they’re ready for college.
Next Steps for You
