During a Fairy-Gala conversation with Jack about his “dogged determination” Vil says that they had the very same argument when they were kids, when Vil cautioned him about training for a marathon in a blizzard and Jack ignored him, getting sick as a result.
There is a similar exchange during Cloudcalling, where Jack insists on taking place in the tournament despite fainting from heatstroke and Vil cautions him with, “That stubbornness of yours is your greatest strength. But also your greatest weakness.”
Jack reveals to Rook that he and Vil attended the same school prior to NRC “for like a year or two.” Vil has more stories, mentioning another time Jack refused to play tag with friends to climb a tree for exercise.
Jack relates a time when they went out to play together in the snow, which ended with Vil having Jack make him a life-sized throne. Jack says that he did most of the work, with Vil saying that he did the entire design and assisted plenty with the decorations.
The two also took skiing and snowboarding lessons together, with Jack giving Vil tips as he was already skilled at both, but Jack says that he barely taught him anything due to how fast Vil mastered them.
Jack expresses gratitude for Vil’s involvement during Fairy Gala, saying that he is “honored” to be coached personally by Vil, and saying it was fun to compete with Vil during New Year.
Vil says that he and Jack are alike in how they both work continuously to achieve their goals.
In a vignette we see Jack and Vil go on a morning run together, with Jack saying that Vil is “pretty impressive” and he had not expected Vil to be able to keep up with him. Vil responds, “Morning workouts are part of my daily routine. You’d do well not to underestimate me,” and Jack apologizes.
Vil impresses Jack by explaining how he tries to cultivate beauty into everyday activities like taking a drink and using his phone, with Jack saying, “So pursuing beauty is kind of like athletic training. That’s real disciplined of you.”
After Vil explains the kind of research that he puts into crafting his own skincare products Jack says it sounds just like the experimenting he does with different protein sources and exercises: “Funny to think we’ve both been going after our goals with basically the same method.”
Jack says that he can “learn a thing or two” from Vil, whom he describes as “self-improvement personified.”
Lilia says that he is surprised by how well Jack and Vil get along and Vil explains, “I have nothing in particular against Jack. Anyone who is working towards a goal, no matter what it is, deserves respect.”
