Abe refines this proof-of-concept and builds a stable time-apparatus ("the box"), sized to accommodate a human subject. Abe uses this box to travel six hours into his own past — as part of this process, Abe sits incommunicado in a hotel room, so as not to interact or interfere with the outside world, after which he enters the box then waits inside the box for six hours (thus going back in time six hours) — Once he exits the box, Abe travels across town, explains the proceedings to Aaron, and brings Aaron back to the self-storage facility housing the box. At the facility, they watch the earlier version of Abe enter the box.
