Hola,
In a Spanish show, a character says to another:
Tú no sales de aquí hasta que no me traigas a ese chico.
Which I believe roughly translates to "You are not to go out until you bring this guy to me." If that is the case, could you explain why the subordinate sentence would be negated with no. Wouldn't it be:
Tú no sales de aquí hasta que me traigas a ese chico.
Thank you for your help!
