The stress of his responsibilities has effects on Samaritan. With little time to himself, he often (though silently) grouses that the need to fly rapidly to various locations to stop crimes and prevent disasters leaves him little time to enjoy the sheer sensation of flight. He also frets over the fact that he cannot be omnipresent and deal with every problem that warrants his attention. His problems are further compounded when, on a time-traveling mission back to his home future, he discovers that saving the "Challenger" changed the timeline (as planned), turning the barren wastelands he came from into a prosperous near-utopia. However, this also results in a paradoxical future in which he never existed; thus, he has no home to which he could ever conceivably return.
