Y, Dad's Going to Come Get Me?

Joseph doesn't, excuse me, not jacob. Joseph doesn't know the details that we know. The assumption that joseph has to make as, my dad's going to come get me, and dad never comes. Instead, he gets sold to these traitors. He still has to think, well, dad will come find me. I mean, how bad does jacob love this son, right? Is his favourite son. Father'll come find me in egypt. Dad'll confine me. Never shows up. And at what point does joseph just kind of give up on this story of, man, i thought my dad would come after me.
