The Boys Season 5 Episode 4 Sparks Backlash — Now Fans Fear the Ending
At the halfway mark of its final season, The Boys hits the brakes with Season 5, Episode 4, King of Hell — its most divisive hour yet, trading endgame momentum for a polarizing slowdown.
Halfway through The Boys final season, the show hit the brakes instead of the nitro. Episode 4, 'King of Hell,' is the first real divide of the season: some folks are fine with the detour, plenty are not, and the word 'filler' is getting tossed around like a Vought NDA.
So what actually happens in 'King of Hell'
- Most of the key players converge on Fort Harmony, a Vought medical facility. Homelander and Soldier Boy are there. Most of the Boys are there. Annie is off on her own, visiting her dad.
- Inside Fort Harmony, the Boys start turning on each other under the influence of something weird in the building.
- The culprit is Quinn, a mutated human-plant Supe tied to Soldier Boy's past. Soldier Boy ends up killing Quinn.
- Meanwhile, Annie tries to patch things up with her father and learns more about (and tries to connect with) her brother. Quiet, but good character material.
- Soldier Boy briefly locks up his son, Homelander, and blasts him with radiation. Homelander walks out of it, and the pro-Vought crowd spins it into a miracle — he's suddenly being hailed as a prophet.
- And after all that? Everyone's still after the same MacGuffin: V-One.
Why fans are calling it filler
Reddit and X lit up pretty fast. One Redditor vented, 'waited a week for this stupid filler episode man.' Another called it 'Definitely a back door pilot for Vought Rising in some way. Weird filler vibes.' And this one on X captured the mood:
'having a filler episode in a final season is crazy.'

The frustration is understandable: there are only four episodes left, and this hour mostly parked the plot right where it started.
Was it really that bad?
Short answer: no. It's fine. Not great, not a disaster — just a middle-of-the-road chapter with a few fun scraps and some legitimately nice beats for Annie. But if you yanked it out of the season, the main story and most arcs wouldn't lose much, which is exactly why people are salty.
The numbers back up the 'fine' read: it's sitting at 8.1/10 on IMDb. That's the lowest of this season so far, but nowhere near the show's bottom — that would be Season 4, Episode 2, 'Life Among the Septics,' at 7.2.
The prequel shadow hanging over it
What really sticks out is how much it feels like runway for the Vought Rising prequel. Quinn's mystery, name-drops like Bombsight and Stormfront, and Soldier Boy's raw, not-fully-explained reaction all scream 'we'll unpack this in the spinoff. ' Cool if you're building a universe; odd choice when you're in your final season and need your payoffs now, not later.
Final-season pacing vs actually landing the plane
There's a balance here. People begging for speed should remember what happens when you rush a finale — hi, Game of Thrones Season 8. Slowing down can work if the character work is sharp. This episode didn't quite stick that landing, but the last beat with Homelander being canonized as a prophet sets the table for a spicy back half.
