HBO’s Task keeps proving it’s not just another crime thriller. At first, the story seemed like a straightforward game of cat and mouse between the FBI and a robber. But by Episode 3, the series takes a sharp turn that makes us question every loyalty on screen.
We already knew Robbie Prendergast was pulling off robberies against the Dark Hearts biker gang. What we didn’t know was that someone inside the gang was quietly feeding him secrets. And that changes everything.
That’s the real hook of Task: it isn’t just about who’s chasing who, it’s about who’s leaking information, and why.
Who is the Leak in Dark Hearts?
Episode 3 finally answers the question we’ve been asking: the person slipping Robbie intel about the gang is Eryn, Jayson’s partner, and in a heartbreaking twist, Billy’s former lover.
This disclosure changes the whole story. Then, it is no longer about crime and survival, but about betrayal, mourning, and the gradual task of revenge.
Why Eryn Betrayed the Dark Hearts in Task?
Billy, Robbie’s brother, had once been part of the Dark Hearts. But when Jayson discovered Billy’s affair with Eryn, his fury turned deadly. He beat Billy so savagely that he didn’t survive.
For Eryn, that loss was devastating. Staying with Jayson keeps her alive, but it also gives her the perfect cover to strike back from within. Her alliance with Robbie isn’t just about passing along information, it’s about making Jayson suffer for what he did to Billy.
Why Robbie and Eryn Join Forces?
Robbie has his own reasons. He’ll never forget how the men who killed his brother later showed up at Billy’s funeral, pretending to grieve, shaking hands like nothing had happened. He always knew Jayson was guilty, but he had no proof. Eryn gives him exactly what he needs: inside knowledge.
Together, they start robbing the gang’s stash houses. Every hit makes Jayson look weaker in the eyes of his crew. For Robbie, it’s vengeance and survival.
For Eryn, it’s revenge wrapped in patience, an unrelenting plan to destroy Jayson from the inside.
What Happens if Jayson Finds Out the Rat?
The fact that Eryn leads a life of two people causes all scenes with Jayson to be like a bomb detonating. Provided that he finds out about her betrayal, then she might face an even worse destiny than Billy. Yet she stays, calm and calculated, determined to keep pushing him closer to the edge.
Meanwhile, Robbie’s robberies put Jayson under fire. Losing twelve kilos of fentanyl doesn’t just hurt the Dark Hearts’ business, it puts Jayson’s life on the line with his own men. And all of it traces back to Eryn, the rat inside his house.

Final Verdict
So, who is the rat in Task? It’s Eryn. But her identity is not the end, but the start of a really dangerous game. How long will she be able to keep her secret before Jayson finds out the truth?
It is not merely a twist of her betrayal. It is the emotional gist of Task, a love tale become tragic, sorrow becomes rage, existence becomes revenge.
And, at least, what we have learned so far with the help of this show is that no one, not even the rat in the shadows, is completely safe.
