The Boys’ episode four takes us deep into the mysteries behind Fort Harmony, a location that’s important to Vought and Soldier Boy’s history. With this show coming to an end and the prequel Vought Rising on the horizon, we knew we would start getting some threads and questions that would likely come up in the future. That really starts to come into focus in this episode. Here’s how The Boys season five sets up Vought Rising.
Sage and Soldier Boy have a quick conversation, in which she reveals that Homelander will soon be on his way to Fort Harmony. Like Butcher and crew, Homelander knows there’s a possibility that V1 is there, a drug that would make him immortal. We also learn that this is where Soldier Boy was injected with V1 by Frederick Vought, which is something we might see happen in Vought Rising.
Soldier Boy decides to go with Homelander and, on the way there, they have a very uncomfortable conversation about Stormfront, whom Soldier Boy knew better as Clara Vought. Of course, they both had a sexual relationship with her in different decades, but Soldier Boy seemed to have a deeper emotional connection.
Meanwhile, the Boys are crashing out bad at Fort Harmony, which is full of these gross and Stranger Things-esque tentacles. Well, everyone except Frenchie and Annie, who actually goes off on her own trip home. They are angry and volatile, which Frenchie surmises is because of the water/air around them affecting their brains. He’s done so many drugs that he’s the only person acting normal. They end up in an all out rage to kill each other, which isn’t good because Homelander and Soldier Boy are on the scene.
Soldier Boy pulls a fast one on Homelander, locking him in a room with enriched uranium. It’s not enough to kill Homelander but it weakens him significantly. His intention is to not help Homelander but rather find and destroy the V1. Frenchie discovers a man who is stuck to the wall and covered in those tentacles. Soldier Boy arrives and recognizes this person as Quinn, someone who was around him previously and incredibly jealous of him.

It is Quinn who is radiating hate, and his presence really seems to crack at Soldier Boy’s tough exterior. Frenchie gets into Soldier Boy’s head, making him agitated enough to use his powers to take out Quinn and stop the Boys from nearly killing each other.
Later on, Homelander breaks out and looks like he’s going to laser Soldier Boy, who is despondent and frankly doesn’t care if he dies. Seeing Soldier Boy despondent and crying changes Homelander’s mind, who decides to leave the scene. This all sets up a lot of questions about what happened at Fort Harmony and exactly why Soldier Boy is so deeply affected by this. We will see what happens as The Boys continues to fly through its final round.
