Time travel is the concept of movement between certain points in time, analogous to movement between different points in space by an object or a person.
Some users may be limited to remaining on the same spatial spot of a differing timeline, others may be able to move to a different spatial position. When fully mastering this ability, you can even move back/forward seconds or minutes in time. The full potential of this power is unlimited.
Triggering The Power
Time Travel is a very hard concept to grasp When Five first time travelled he got stuck in the apocalyptic future. Just like Energy Projection, you must have a firm grasp over the power to control it. The time Five spent working at the Temp Commission, was also the time he spent calculating how to travel in time to his siblings. Time Travel can be used in a variety of ways, but it must be mastered in order to be used properly.
Five can travel through time. Five, however, had not mastered this ability, and the first time he used it, he accidentally traveled to the end of the world and was unsuccessful in traveling back. Despite being less adept at time travel, Five is a quick study and in The White Violin, he was able to travel through time and take his siblings with him; something he had never done before. In The End of Something, Five is able to reverse time by a couple of minutes, undoing events during that time so that only he remembers them and can alter events. It is unknown if Five has fully mastered this ability.
