Abe could build a box at the hotel and experiment with it there. From his experiments, Abe plans to record his work and compose a book on the elementary rules and principles for time travel, a primer.
Abe experiments with his watch. He starts the box. After three minutes, he opens the box and removes a watch that is identical to his own. He waits for 57 more minutes before he opens the box and places his own watch inside. Opening the box once again, he finds it is empty. Abe is excited. He repeats the experiment with a live mouse. Upon his success, he rents a unit at the U-Haul. This will be his fail-safe. He starts the fail-safe, rents another unit, and constructs another box. This will be his personal travel box, the one he will eventually show to Aaron.
Abe plans a number of experiments. On one of his time travel days, Abe returns to the hotel to avoid outside interference. As he looks outside the hotel from his room, he is shocked to see Aaron and himself walking into the hotel lobby.
What to do? Abe was not planning to tell Aaron right away. How could this be? Should Abe continue as planned or will he decide to use the fail-safe and attempt to work at a slower pace? Aaron’s rewriting of the past few days, from Aaron’s perspective, would cause Abe to see the future jumping into his present. Abe may be determined to be more secretive and less trusting of Aaron. He may decide that instead of working by himself with his experiments, he may need to keep a close eye on Aaron. Abe will not have the time to write his primer on time travel. All he has time for is a few minutes to scribble down a few main ideas on a piece of paper; four key rules that would restrict the use of the box, preventing any possible harm.
