He sees the shapes of the missing memories.
Childhood. Human relationships. Interests. Rites of passage. Operational details. Organizational affiliations. Rank, identity, purpose.
Faces without features. Motivations without reference to a narrative.
He's faced down armies single-handedly. Held Time in A Bottle. Prevented a grey-goo event that would have destroyed a continent. Caused a grey-goo event by hacking the replicator systems in a fleet of heavy freighters. Killed hundreds... thousands. Men, women, children, ghosts, monsters. Allies. Enemies.
But when?
Why?
And for whom?
