When asked who he would take with him to a deserted island Deuce says, “if you’re going on an adventure, you have to be smart, tough, and brave! By that metric, Jack or Epel would be pretty good to have along…” (he ultimately chooses Ruggie).
Deuce and Epel are in a group together with Azul during Glorious Masquerade, where Azul comments on them being too honest and throwing him off. They both say that they loved playing outside as children.
When Riddle and Epel volunteer to stay behind and fight firelotuses leading up to the fight with Rollo, Deuce tells Epel to be careful, and “Take care of my housewarden!”
Deuce has made multiple comments on how “You’d never guess it by looking at (Epel), but he’s got a whole lot of grit.”
Deuce mentions receiving candy from Epel in a voice line.
Both Deuce and Epel are against wearing bunny costumes for White Rabbit Fes, but when every other character is in favor of doing so Epel wonders, “Maybe we’re the weird ones?”
During the event, Epel shares his dream with the group: “To cruise around on blastcycles with my pals wearing matching leather jackets!” Deuce says that he hopes he is invited, and Epel responds, “You bet! We’re gonna run wild!”
After the group ends up registering for a foot race to force bullies to apologize to Deuce’s mother for their poor behavior Deuce apologizes for getting them involved.
Epel says, “Think about it: all of us running wild, together, in matching outfits…It’s just like l’ve always dreamed about!”
During the event Epel shares a rumor about a local delinquent that he was obsessed with learning about in middle school.
Deuce claims to have never heard of him, but later in the event it is revealed that Epel’s middle-school obsession was actually Deuce himself.
