(LOCATION: Inside a car of the armored train, "The Behemoth." The train is speeding through a completely dark tunnel.)

(The episode opens with a wide shot of the crowded train car. The lighting is dim, coming from a few emergency lamps, and many passengers are using strange, glowing fungi for personal light. The atmosphere is quiet but tense. The only sounds are the roar of the train and the creaking of metal.)

(The camera moves between the five heroes, who are seated in a secluded corner.)

 * BILAL is pressed against the small, reinforced window, trying in vain to see anything in the absolute darkness.

 * QASSEM sits beside him, but his gaze is distant, watching his own reflection in the glass.

 * MADDAH isn't looking outside, but is carefully observing the other passengers, analyzing their faces and clothes.

 * TAHER sits upright, constantly alert, his eyes scanning the car.

 * MERENJI fidgets with obvious boredom, tapping his fingers on his knee.

[SCENE 2]

(To show the nature of this world, we hear snippets of conversations from other passengers.)

WOMAN: (Whispering to her husband) "Do you think the tests in Oran are real? Can we really get out of the Bottom?"

HUGE MERCENARY: (To his comrades) "Last time we passed through this sector, we lost two men to 'Tunnel Crawlers.' Stay ready."

OLD MERCHANT: (To a customer) "Three coins for this glowing mushroom. It's better than the dark, isn't it?"

(Each conversation adds a new layer of the desperation, danger, and hope that fills this journey.)

[SCENE 3]

(Maddah's curiosity leads him to the old merchant, whose name is IRFAN.)

MADDAH: "This fungus… does it grow in the tunnels?"

IRFAN: (With a toothless smile) "It's the only beautiful thing that grows in this darkness, my boy. It's food and light all in one. But the tunnels are not empty. They are full of legends… and dangers."

(Irfan begins to tell a story about the "Iron Hunters," a gang of tunnel bandits who prey on trains.)

MERENJI: (Overhears the conversation and approaches, scoffing) "Bandits? Let them come. I'll turn their vehicles into scrap metal."

(The mercenary leader sitting nearby gives him a cold look, as if to say, "You know nothing, kid.")

[SCENE 4]

(Feeling bored and slighted by the mercenary's look, Merenji gets up and walks over to their table where they are playing a strange card game.)

MERENJI: (Arrogantly) "Is there room for a real player, or is this game just for beginners?"

(The mercenary leader slowly looks up. He doesn't speak, but simply gestures to an empty seat. A tense game begins, not just with cards, but with glares, bluffs, and veiled threats.)

(Merenji is about to lose, but Maddah, watching from a distance, notices the mercenary has a "tell"—he scratches a scar whenever he's bluffing. Maddah gives Merenji a subtle signal. Merenji understands and wins the next round, earning a grudging nod of respect from the mercenary.)

(Taher pulls him away by the arm.)

TAHER: (In a sharp whisper) "Stop drawing attention to us. We're not here to play games."

[SCENE 5]

(Later, the car has quieted down. The tired Bilal has fallen asleep, his head resting unconsciously on Taher's shoulder. Taher looks down at the sleeping boy, and for the first time, a gentle, unguarded expression appears on his face.)

(Qassem, who has been silent the whole time, notices.)

QASSEM: (Quietly) "You're good with him."

TAHER: (Without looking up from Bilal) "Someone has to be."

(It's a short, quiet moment of connection between the two most serious members of the team, built on their unspoken, shared sense of responsibility.)

[SCENE 6]

(FINAL SHOT: As a calm atmosphere settles in, a loud, terrifying sound is suddenly heard… the sound of metal scraping on metal coming from the roof of the train car.)

(Everyone in the car freezes. The mercenaries grab their weapons. The woman clutches her child tightly.)

(The old merchant, Irfan, whispers with genuine terror as he looks up.)

IRFAN: "The Hunters..."

(The camera focuses on the terrified face of the child from the hopeful family, staring up at the ceiling as the scraping sound gets louder and closer.)

(The screen cuts to black.)
