Though Chapter 6 is largely an April Fools' Plot, it's revealed that Emmet absolutely loves his new job because it gives him a chance to encourage others and help them feel important, just like how he used to feel now and then.
And his ideal ending...? He wants to give a special speech on Taco Tuesday admitting how he used to feel like he didn't matter, and that everyone is, no matter what... And then afterward? He wants to just hang out with his boss and have some tacos together, like close pals.
Bad Cop telling Good Cop he should be the one to present the Piece of Resistance to Lord Business, so his past weaknesses on the job will be forgiven.
