Why read this explainer

Compare the Carlos and Treadstone conspiracy with the film's narrower pursuit by Bourne's handlers. Marie's immediate companionship also changes the pace of the personal alliance within the chase.

PlotGeeks note

Marie becomes an immediate companion in escape rather than a slower professional and personal ally. The narrower pursuit concentrates both the spy conflict and their relationship.
