Jevil references?!

!​!<Like any normal person I am playing chapter 5 and happened to notice the sheer amount of references to jevil. the world revolving is referenced at several points, I’ve seen it so far only in the blue and yellow fight and I think cyan unintentionally references it at one point. Also, Ralsei at one point outright just saying he liked the rubber ducky from jevil’s act. so Im just wondering if anyone else was wondering why they mention him so much? I mean, devilsknife even got a new ability for crying out loud!>!​!<
