Season 1 episode 10 “Damien” is the first episode where Pip is relevant to the plot. During the episode, he befriends Damien, the Anti-Christ, who is also an outcast, and unwillingly helps him become liked by the rest of the class. Just like Pip, Damien was originally from a book (though The Omen book was written as a novelization of the film, it released 3 weeks prior).
I tried to finish this drawing of Extrazball because I saw on Pinterest how they did it but with an image from the "Ring of Fire" video, but with Damien I had some difficulties so I didn't finish it
