Sleeper.exe’s holiday: A Tate End Friends prequel of what Sleeper.exe was doing during Arrow End Friends. Knives tells him, he is no longer their interest, at the same time, Sleeper.exe admits “Being a villain is boring”. So, Sleeper.exe starts to go on vacations (It’s more of a short film rather than a movie) It basically is about Sleeper.exe going around the world.
