Boy: You don't pay me to work for you.
Woman: No, because what you do here in the workshop isn't a real job.
Boy: It isn't a real job?
Woman: No. I'm training you for a real job later.
Boy: You're training me?
Woman: Yes, I'm training you or teaching you what you need to know later.
Which is correct:
1-what you need to know later.
2- what you'll need to know later.
