Gi Joe A Real American Hero (Sunbow)

The Traitor (Part I) (1x46)

:

G.I. Joe designs a new armor treatment that's impenetrable to laser fire and missiles. While on leave, Dusty is desperate after seeing his mother struggle with her asthma and mounting medical bills, so he makes a deal with Extensive Enterprises' Crimson Twins to pay for the costs in return for the armor formula. He secretly informs Cobra about it, leading his team into an ambush that left Duke in a coma. Now the Joes have a traitor in their midst.
