Panel 1:
Nancy, a little discombobulated, is bundled up the carriage by Mayweather. The door is wide open.

NANCY: How did you-?

MAYWEATHER: Chambers called the driver, she’s filled us in.

MAYWEATHER: She’s got a plan, get the guy on top to the front of the train and keep him there.

NANCY: Why…?

Panel 2:
Lewis slips through the door as it’s sliding shut and is immediately clotheslined by Mayweather’s pole. Nancy rushes ahead.

MAYWEATHER: There’s no time! Go!

LEWIS: Huickh!

Panel 3:
Mayweather has Lewis pinned with her pole, but Lewis’ gun makes it a stalemate. Mayweather is suitably wary.

LEWIS: Miss Mayweather, I presume?

MAYWEATHER: “Found a job at another school,” eh?

MAYWEATHER: Awfully confident for someone I’ve never met, officer.

Panel 4 (slim):
Mayweather narrows her eyes.

MAYWEATHER: Or…

MAYWEATHER: ...wait…

MAYWEATHER: ...maybe I have?

Panel 5 (slim):
Same view. Mayweather watches the pole being kicked out of her hands.

MAYWEATHER: Guckh!

Panel 6:
Lena stretches her arms to block the carriage as Lewis legs it and Mayweather picks up her things. Nancy’s already through the partition door.

Panel 7:
SFX: BLAM

Lewis shoots and shoulders through the nearest window. Lena slumps.

LENA: …

LENA: ...I helped.
