What was Joseph ranting about?
At the climax scene where Joseph had enough with the young Sean, we can hear him screaming with these lines:
"He has no clue how to make something happen. He's living in a land where he's pretending to be something instead of doing the job. And that's the real problem. I'm the one who should be respected, but obviously not"
It does not sound like he's talking about young Sean. So who or what was Joe ranting about? And why?
