Hi, I saw a dialogue in tv series Better Call Saul. It was "I am not telling you anything until we talk about my dad " and French translation is "Je ne te dirai rien tant qu'on n'aura pas parlé de mon père.. What I want to ask is why "parlé" is used instead of "parler", why passé composé form is used in this sentence after future tense of avoir.
Thank you.
