When a mutant who can time-travel finds David and his cult, she goes on frequent trips back in time in an attempt to prevent a tragedy from befalling David.

With his eyes set on using Switch's time-travel to fix everything, David proves willing to cross many boundaries to achieve his goals.

David experiences the events that led to his possession by Farouk and inadvertently contributes to his family's trauma.

With the timeline becoming unstable due to frequent tampering, everyone falls victim to time demons who trap them in nightmarish illusions.

With David on the hunt for Switch, the traumatized Lenny is driven to take drastic measures to deal with the guilt. Syd's last attempt to stop David runs into a major problem.

With Syd's mind lost on the astral plane, she gets taken in and raised by supportive parents to a point where she can attempt a return to the real world.

With David trying to change the past and influence his father's actions, time threatens to destabilize with the time demon arriving to attack and Switch's powers running amok.

Switch's powers climb to unprecedented levels. David's actions have unforeseen consequences for him and Syd.
