Moments after making this discovery, he's arrested by colonel Amos, director of the FBI's anti-terrorist department and accused of the murder of William Sheridan, the 43rd president of the United States.
Wanted by all the cops in New York State and hunted down by The Mongoose, the amnesiac seems doomed to a choice of death or prison.

During their escape, this foxy lady reveals to XIII that he's a secret agent working for General Carrington.
