IntheAbbott Elementarypartof theIt’s Always Sunny in Philadelphia, we hardly see Dennis, as he says he doesn’t want to be in front of cameras. However,It’s Always Sunnyseason 17, episode 1 (part 2 of that crossover event) finally reveals what he was doing. As it turns out,he was doing a “science experiment” with coffee.

This is one of the ongoing bits throughout the episode, asit’s revealed that the teacher’s lounge coffee was poorly made and tasted like “sludge.“This led Dennis to set out and try to make the best possible coffee. He stole supplies from the science lab and was making coffee orders all day for the Abbott Elementary staff.

Dennis' Hidden Abbott Elementary Story Is Much More Tame Than Expected

A Surprisingly Wholesome Act From The Man Who Created The DENNIS System

Since Dennis stated that he wanted to be off-camera in theAbbott Elementarypart of the crossover, his story seemed like it would end up being a lot darker. Of the five mainIt’s Always Sunnycharacters,he’s almost certainly the worst morally, and yet he’s the only one who actually contributes something positiveduring their time at the school.

His story was really tame, even if it was just a performative act of generosity for the cameras.

This is the man who takes secret videos of women he sleeps with and has a personal system for emotional manipulation, sowhen he states that he wants to avoid cameras at an elementary school, it’s fair to assume the worst. His story was really tame, even if it was just a performative act of generosity for the cameras.

Strangely, Mac, Frank, and Charlie were the ones who had the darker plotline, eyeing young basketball players to build a team with. Although their intent was simply to profit from children, the scene had an evident, inappropriate undertone, which felt like it could have been Dennis’s. I suppose it’s good to seeIt’s Always Sunny’sscariest character giving back.
