Original Cop Earlier Backstory
The original plot of Cop Earlier (which was supposed to be a trilogy of short films) involved Red Face's Second in Command (pictured below) taking revenge on Giggle Cop, along with the remaining members of the gang, which was originally supposed to include a different version of La Sombrerbra. This is why Sheild/Vest guy shows up in the background and why it says To Be Continued.
