Original LlamaGen editorial resource · English · 2026-10-26. This is a manual planning file, not an AI-generated result, an automatic long-canvas exporter, or a studio timing control.

## Episode brief

- Location and reading direction: One station platform; read downward; keep the platform edge on Mara’s right.

## Filled example: The Last Train

Original editorial fiction, not a measured AI generation. Mara finds a ticket with her name at an empty station; an older version of herself arrives on the train.

## Screen 01 — Set-up

- Action: Mara reaches an empty station with her round satchel. The last-train sign is still lit.
- Shot: Wide station view
- Dialogue / sound: LAST TRAIN
- Rhythm: Start with a wide establishing panel, then a short transition.
- Why scroll next: Why is the station still lit?
- Continuity: Green coat, crescent pin, round satchel; bench stays on the left.

## Screen 02 — Trigger

- Action: A folded ticket on the bench has Mara’s name on it.
- Shot: Ticket close-up
- Dialogue / sound: MARA
- Rhythm: Use a compact close-up so the clue is readable before the next action.
- Why scroll next: Who left Mara a ticket?
- Continuity: One folded corner; the ticket remains in her right hand afterward.

## Screen 03 — Escalation

- Action: Mara looks down the empty track as the speaker announces one passenger.
- Shot: Medium reaction
- Dialogue / sound: Last service. One passenger only.
- Rhythm: Keep the announcement and reaction together; add a brief gap afterward.
- Why scroll next: Who is the one passenger?
- Continuity: The platform edge stays on her right; the satchel remains on her left shoulder.

## Screen 04 — Hold

- Action: Her hand tightens around the ticket. She does not move.
- Shot: Silent hand detail
- Dialogue / sound: [silent]
- Rhythm: A small silent panel followed by a visibly larger blank gap delays the reveal.
- Why scroll next: What will emerge from the empty track?
- Continuity: Show the same folded ticket; do not add a new prop during the pause.

## Screen 05 — Reveal

- Action: The train arrives. An older Mara watches from the window, wearing the same crescent pin.
- Shot: Large window reveal
- Dialogue / sound: [silent]
- Rhythm: Give the identity reveal its own larger panel; let the reader inspect the pin.
- Why scroll next: Why is Mara already on the train?
- Continuity: Match the face shape and pin; age is the intended difference, not a new character design.

## Screen 06 — Next-episode hook

- Action: The door opens. The older Mara holds a second ticket and asks a question.
- Shot: Two-character doorway
- Dialogue / sound: Which one of us gets off?
- Rhythm: End after the question. Leave the answer for the next episode.
- Why scroll next: Which Mara will get off?
- Continuity: Make the second ticket intentional; both Mara versions retain the crescent pin.
