Junior encouraging Yul to keep pursuing his dreams. This is despite the fact that Yul has treated him like crap from the day they met. It's telling that he starts to warm to him after this.
Sanka: Face it, Yul Brenner, you can start calling yourself Madonna, but you're still going to end up in an outhouse shanty like every other dock working nobody.
Junior': Says who?
Sanka: Says me, rich boy! What do you know about it?
Junior: Well, I know my father started off in a one-room hut. Now he lives in one of the biggest homes in Kingston.
Sanka: Well, he ain't your father.
Junior: He doesn't have to be. All he has to do is know what he wants and work hard for it. And if he wants it bad enough, he'll get it. Look, believe me, Sanka, the more Yul Brenners we got making it in this world, the better off this world will be, especially for Jamaicans.
- And then later Yul teaches Junior how to find his own strength.
Yul: Look in the mirror, and tell me what you see!
Junior: I see Junior.
Yul: You see Junior? Well, let me tell you what I see. I see pride! I see power! I see a bad-ass mother who don't take no crap off of nobody!
