A los demás que les importa

A los demás que les importa
 

Hola a todos,

In a scene in the movie Carne de horca Lucero receives a letter and asks to have it read to him.

- ¿Qué? ¿Visteis al tío Lucas?
- Sí, me dio esta carta para ti.
- Lee. ¿Qué dice?
- Que esperemos pasado mañana la diligencia de Córdoba que trae dinero de la Real Hacienda escondido en un baúl y sin custodia para que no lo sepa nadie.
- Lo sabe el padrino que se entera de nosotros.
- A los demás que les importa.

I'm not sure I understand correctly the meaning of the last two lines.

Does "Lo sabe el padrino que se entera de nosotros" mean that el padrino knows about it (about "diligencia de Córdoba que trae dinero") and that el padrino also knows about us?

And the meaning of "A los demás que les importa" is unclear to me. It is a statement, not a question, right?

The scene in question starts at 28:53.

Thank you.

"The godfather who knows about us knows" (about the plans).
It's a statement. "The others don't care."

The dialogue is

- Lo sabe el padrino que se entera de to'o.
- ¡Y nosotros! A los demás qué les importa.

The text in red: both are talking at the same time.

Thank you both very much, Rusty and aleC!

The "Lo sabe el padrino que se entera de to'o. ¡Y nosotros!" part is now perfectly clear to me.

But I'm still a bit unsure about the meaning of "A los demás qué les importa." in this partiicular context.

As far as I can tell, this phrase is written in the letter. Does it mean that, according to the author of the letter, no one has the slightest interest in this stagecoach with money?

I think it means nobody is going to "object"; no-one will try to stop the robbery.

Thank you very much again, aleC!
