In the opening sequence Drew's ribbons include a National Defense Service Medal with 2 service stars indicating 3 awards. That would mean he received his first award during the Vietnam War because the three most recent eligibility periods for that award are January 1, 1961 - August 14, 1974 (Vietnam War), August 2, 1990 - November 30, 1995 (Persian Gulf War), and September 11, 2001 - Present day (Global War on Terrorism).
In one scene, Ananya calls Drew 'Doug'.
