This nameless being, hereafter referred to as Purple, appears next to Tarvek and Higgs as they are on a balcony, preparing to intervene in the summoning by Snacky and the Grey Hoods of another extradimensional being. Purple needs their help, but has trouble asking for it because he gets confused about whether he's talking about the past, present, or future. All of time is the same to him, which is how we know he's an extradimensional being.

After his arrival, Tarvek and Higgs seem to move a bit forward and backward in time between frames, Tarvek more than Higgs because, we soon learn, Higgs' extremely long life anchors him somewhat in time. Purple borrows some time-stability from Higgs to give to Tarvek.

But instead of explaining why he needs help, Purple next appears on the floor in media res, where he meets Dimitri Vapnoople, who tries to tell him why people need monsters, but can't quite explain himself because the Baron "took my words." Purple can observe the confusion in Vapnoople's brain, is curious about what he would say if he could, and therefore, with a hand on his shoulder, repairs his brain. This turns out to be unfortunate, because, along with his words, Vapnoople regains his (typically crazy spark) intention to improve the human race by creating monsters superior to people, so that only the best (smartest, strongest) human beings survive.

This distresses Purple. Can he/will he undo his brain surgery? Stay tuned.
