Coffee committed such an act that would make their mistreatment worse. By the events of the Star vs. The Forces of Evil Season 3 Finale, Anewas refused to leave the dimension when the other monsters did since he found purpose when meeting a stranger just like him: Saetha, who hails from the Alternate UUniverses seeking the excitement of the OUU though would then come into the sub-dimention of Mewni, as he has been falling in love with her. Thus, he and Saetha became another world-jumping couple since Star Butterfly and Marco Diaz disappeared. But they don't know that Coffee, feeling abandoned and insulted by his own friend for leaving the army after what Mewmans did to his family and to his brother's finger, felt he was redundant to him and monsters as a whole, agreeing with Toffee's bias against discrimination, and swore revenge for denying him a chance to get payback.
