The bully introduced towards the end of the previous season reveals his name to be Niles, and he promises to help Melony train her powers. When it is discovered that the Box Club is trying to summon the God Box, SMG1 and SMG2 explain that the God Box is a dangerous artifact that they must prevent from being opened if it exists. Later on, SMG4: Absolute Betrayal premieres and the Revelations Arc, which had secretly been started towards the end of the previous season, begins. A day before the final exams, the Box Club abducts Melony and imprison the gang when they try to stop them. Niles is then revealed to be the imperfect Meme Guardian who possesses Melony's mind after his and SMG0's spirits got split. Niles possesses Melony and makes her open a portal to The Great Beyond to find the God Box. This is eventually followed up by a 49-minute movie: SMG4 Movie: REVELATIONS, concluding the Revelations Arc with the revelations of SMG0's past, the deaths of Niles, SMG0, the Box Club Leader, and Terrance, and Meggy and Melony's graduations from Omnia Academy and achieving their future careers (mainly by Meggy).
The true nature of the fabled God Box is revealed.
