one has to leave
We must leave here quickly.
Hay que irse, no podrás ayudarlo.
We have to leave; you won't be able to help him.
— Guardianes de la noche (2004)
En fin hay que irse hay mucho que hacer.
Well, we have to go, there's a lot to do.
Cuando hay que irse, hay que irse.
When you have to go, you have to go.
