Sergeant Jeffords: Can I ask why that card is so important?
Captain Holt: Because of Zeff Wilcox. He was a victim in the first case I worked. I always want to remember him.
Sergeant Jeffords: That's nice.
Captain Holt: And the words he wrote on the back.
Sergeant Jeffords: The back... say what, now?
Captain Holt: Why is this blank?
Sergeant Jeffords: I threw it away. I thought it was trash. I didn't know you kept it to remember someone you helped.
Captain Holt: I didn't help Zeff, I failed Zeff. His case was never solved. The words written on the back were: "Thanks for nothing."
Sergeant Jeffords: Oh, man, that's rough.
Captain Holt: I have held onto that card for 30 years because I always wanted to remember what it felt like to let someone down, so I'd never do it again. That card made me the cop I am today. Without it... I'm lost.
