After the white-knuckle chaos of Episode 3, Hijack Season 2 finally feels like it knows exactly what kind of story it wants to tell. “Baggage” didn’t just raise the stakes, it rearranged the board entirely. By the time the train lurched back into motion, we learned a truth that Sam Nelson isn’t orchestrating this nightmare. He’s surviving it.
Episode 4 is going to be the chapter where that illusion of control collapses, and where the real antagonists begin to step out of the shadows.
A Moving Train, a Ticking Clock
With the train back on the tracks, Episode 4 will likely open with a fragile sense of forward momentum. GSG 9 has been forced to retreat, the authorities are scrambling to reassess, and Sam has successfully convinced Winter that the threat is real. But this “progress” comes at a cost.
The bomb beneath the train changes everything.
No longer can law enforcement afford small miscalculations or psychological games. Any attempt to stall, derail, or forcibly stop the train could trigger catastrophic consequences. Episode 4 may revolve around a terrifying question - How do you neutralize a threat you can’t even access?
Intense discussions are expected inside control rooms, hurried consultations with explosives experts, and mounting pressure on Winter, who now realizes she’s negotiating with a man trapped by forces far larger than himself.
Sam Under Suspicion From All Sides
Inside the train, Sam’s position is more precarious than ever. Freddie’s death has transformed him into a villain in the eyes of the passengers, regardless of the truth. Even if some sense that something isn’t adding up, fear has a way of simplifying complex situations.
Episode 4 could explore the psychological fallout of that mistrust. The passengers may begin resisting Sam openly, refusing to follow instructions, or even attempting to overpower him. Otto, already conflicted, might start questioning whether staying aligned with Sam is a death sentence.
This internal fracture could be just as dangerous as the bomb itself.
Sam’s greatest weapon has always been persuasion. But now, with blood on the platform and panic in the carriage, his voice may finally lose its authority.
The Puppet Masters Step Closer
One of Episode 3’s most shocking reveals was the existence of an unseen force monitoring Marsha and manipulating Sam’s every move. Episode 4 is the perfect moment for that presence to grow louder, more demanding, and far more cruel.
The anonymous messages may escalate in urgency, issuing impossible deadlines or forcing Sam into morally unthinkable choices. Fan theories suggest that this group isn’t acting alone and that their endgame may have nothing to do with Sam’s grief or John Bailey-Brown’s crimes.
Instead, Sam could merely be the delivery system for something much larger: exposure, political leverage, or an intelligence scandal that could destabilize multiple agencies.
If that’s the case, Episode 4 might offer our first real hints about who’s truly behind the curtain.
John Bailey-Brown: Asset or Liability?
Now that MI5’s protection of John Bailey-Brown has been exposed, Episode 4 could turn him into the story’s most volatile piece. Is he worth the risk MI5 is taking? Or is he already more dangerous alive than dead?
There’s a strong possibility that pressure mounts to move JBB, either to secure him further or to use him as bait. A covert attempt to relocate him could backfire spectacularly, especially if the same unseen observers watching Marsha are watching MI5 too.
Some theories even suggest that JBB himself may not be as powerless as he appears. Episode 4 might hint that he’s been anticipating this moment and that his role in Kai’s death is only part of a much darker history.
Winter’s Breaking Point
Winter has spent most of the season trying to stay one step ahead of a situation designed to humiliate her. Episode 4 may push her past the point of professional detachment.
Armed with the truth about the bomb, MI5’s deception, and Sam’s coercion, Winter is now standing at a crossroads. Does she continue playing by the rules of agencies that have already lied to her? Or does she take a reckless gamble to save lives?
Her relationship with Clara may deepen here, shifting from procedural cooperation to genuine trust. But that trust could come at a cost especially if Winter chooses to leak information, disobey orders, or act unilaterally.
One wrong decision, and the train isn’t the only thing that could explode.
Marsha in the Crosshairs
Episode 4 is also likely to focus more intensely on Marsha, who remains the emotional linchpin of the season. So far, she’s been a distant but powerful presence, a hostage without chains.
The people threatening Sam could escalate their surveillance into direct action, reminding him exactly how little room for error he has left. A near-miss, a warning, or an encounter meant to terrify rather than kill could push Sam closer to the edge than ever before.
If Marsha realizes she’s being used as leverage, her response may not be passive.
A Setup for Collapse
Rather than delivering immediate payoff, Episode 4 will likely function as a pressure cooker; tightening every screw, isolating every character, and stripping away any remaining illusions of safety. The train is moving, yes, but it’s heading straight into uncharted territory.
By the end of the episode, expect a cliffhanger that changes the rules yet again: a new demand, a shocking betrayal, or the first real move against the bomb beneath the train.
