Unidentified Man (Air Force One; appears in flashback)

An unnamed man who appears in the narrative both as a present-day passenger aboard Air Force One—striding toward the cockpit in the predawn hush and catalyzing an immediate security escalation—and in a related flashback sequence. Identity and motives remain unconfirmed; the figure functions as a narrative catalyst for the episode's security response and appears across temporally separated scenes as an anonymous, urgent presence.
