As the boy pulls the broom to him and begins sweeping, a voice crackles into a distant speaker. It is Poe, saying ‘We are not alone. What our mothers and fathers have fought for we will not let die. Today we make our last stand…for the galaxy!’ Many ships jump into hyperspace here, not just one.

Goosebumps.

Edit: Since Crait is now the opening of the film do you plan on including palpatines broadcast in there in some capacity? After the galaxie’s decline to help, hearing the broadcast could be what sets up the rallying of the people’s Fleet at the end of the film.
