Timeline

The Timeline Arc refers to the first time the characters stumble upon the diverging timelines which become prevalent in the later seasons of the show. On the night of Friday the 13th, Jason, Jupiter, and Forrest decide to drink, while Tyler decides to abstain; however, Tyler eventually gives in and joins. This discrepancy between his normal character and the decision he makes creates a rift in reality and sends the characters into a new timeline. As the normal timeline continues off camera, the characters at first don't even notice the discrepancy; it is only once they visit Elevation for wing night, notice that the staff and ambiance are radically different, and learn of Rebecca's death, that they realize they are in a corrupted timeline.
