Jexter travels back to some point in the past when he went by a different name and had a different appearance from 2018-2019, criticizing his simplified and bizarre older design from the past decade at the tail end of the 2010s while Jesse can't believe he's changed his outfits to something more recognizable and more appealing and interesting giving himself more personality and expressiveness. Yes this is a reference to that scene from Scooby-Doo and The Cyberchase (2001) and inspired by an artist on FurAffinity and DeviantArt.
