Journey to the End of Time, the Astonished He Who Remains

Peter was like a ghost traveling through the timelines, observing the development and evolution of the Time Variance Authority. Of course, he had little interest in the Time Variance Authority's history. After only a brief look around, he traveled through time and arrived just before the timelines completely collapsed, taking the entire Time Variance Authority and the Infinite Universe down with them. There, he saw Loki constantly traveling through time, trying to save every timeline and the entire universe.
