whatever I have to do
Creo que tal vez eso sea todo lo que tenga que hacer.
I think that might be all I have to do.
Do what you have to do.
Yo haré lo que tenga que hacer.
I'll do what I have to do.
— Investigación sobre un ciudadano libre de toda sospecha (1970)
Y su padre hará lo que tenga que hacer por los suyos.
And his father will do what he has to do for his family.
