They establish the protocol of using the time machine to create loops, allowing them to avoid temporal conflict and preserve knowledge from the original timeline.
Both men uncover complications such as duplicate selves and unexpected consequences, including memory issues and physical stress.
Aaron secretly constructs a second time machine to extend his time traveling independently of Abe, causing tension between them.
Abe confronts Aaron about the unauthorized time machine, expressing concern about safety and the fallout from unsynchronized looping.
Abe attempts to reset the timeline to undo the damage caused by unauthorized time traveling, but unintended consequences arise.
The timeline becomes ambiguous as multiple loops and copies of Abe and Aaron exist, signaling unresolved consequences.
