SSA David Rossi ran into his Sergeant from Vietnam while the BAU was on a case in Los Angeles. Sergeant Scott had fallen off the wagon and was living on the streets near the beach. Sergeant Scott revealed to Rossi that his alcoholism – and subsequent homelessness – was a result of guilt for having accepted an award that he hadn’t earned.
When pressed, Scott told Rossi that while the their platoon was in the fields of Vietnam, a fellow Marine named Hernandez died when he jumped on a landmine to save their lives. Afterwards, Rossi and Scott presented Hernandez’s grandson, also a Marine, with the medal that his grandfather earned long ago.
At the end of the episode, Rossi dedicated his most recent book, Evil Never Rests
, to Scott and Hernandez, “two men who saved [him] so that [he] could save others.”
