Charlie (Charlie Day) finally learning to read a little bit. Notably, though, Dee’s brother Dennis (Glenn Howerton) was nowhere to be found.
In the crossover, the “Always Sunny” gang are on volunteer duty at Abbott Elementary (as part of court-mandated community service, of course), and when Dennis learns that Abbott has a documentary crew that follows the teachers and other staff around, he wants no part of it. It’s somewhat understandable, given Dennis’ embarrassing on-camera meltdown when the gang went on the game show “Family Fight,” but it’s also kind of ironic given just how often the character records people without their knowledge. Now, thanks to the “Always Sunny” half of the crossover, we know where Dennis went while the rest of the gang wrought havoc upon the school, and it’s honestly pretty typical Dennis.
