Several theories on EC3.
Feel like Vince may feel he’s already got an EC3, so he doesn’t feel like making another one work...especially one he didn’t establish. The character is named after Dixie.
Also, perhaps, he’s making it a point to go: “You thought I’d put him over because this is the look I’m supposed to be into? Let me show you how much I don’t give a fukk.”
...but it’s probably from Bateman rubbing people the wrong way before leaving and him paying debt from back then. I always figure when people get buried hard but featured fairly heavily, it’s carny justice in action.
