Jake: You see, Melanie, after the last attempt to rescue my father failed, I spent months trying to figure out what went wrong. Eventually, I came to understand the nature of what was happening to him. It was as if he was frozen in time at the moment of the accident, and the link between us was like an elastic cord. Every so often the cord would go taut enough to yank him forward into my time. But only for a few minutes. I realized that if my motion through time came to a stop, the cord would go slack and he'd be lost in subspace forever. But if I could cut the cord when the link was at its strongest, while we were together, he'd return to the moment of the accident.
