Deroy Remakes the Universe

In this Ultimate Stop Holding Back, Deroy changed everything by completely invalidating all of Season 2. Good job, Noah.

Universe A
Universe A ("the universe with Deroy") was the old universe containing Martha. When Li deceived everyone into thinking Martha killed the entire auditorium, Deroy deleted Universe A from existence, replacing it with.

Universe A's Deroy is known colloquially as "old Deroy".

All events before S3 occur in Universe A.

Universe B
Universe B ("the universe without Deroy") is the universe that replaced Universe A when Deroy remade the universe and transformed into a metacosmic custodian. In the universe without Deroy, all traces of Martha have been annihilated. Old Deroy's presence is still felt in the form of golden light.

Confusingly, the universe without Deroy also has a Deroy. However, Universe B's Deroy doesn't have powers.

All events after S3 occur in Universe B.
