Most of the action in G.I. JOE #3 is set inside Duke‘s mind as Dr. Mindbender tries to break the JOE and force him to give them the all-clear code which will allow Cobra to continue their plans. Various memories of Duke from childhood through the circumstances that led to him to enlist with the JOEs are used to try and break Duke, but Mindbender and the Baroness discover the process isn’t as easy as they had hoped.
The issue is a good excuse to delve into Duke’s past and present a new look at the road that led him to being the field leader of G.I. JOE. Most of the flashbacks have to do with Duke’s relationship with the love of his life who he lost twice, once by stopping her transfer into the field, and later when her bullheadedness got her the assignment she wanted only to die in an ambush set for Duke.
G.I. JOE #3 bucks the trend of “everybody breaks” in comics and movies recently by allowing Duke to hold out and even warn the JOEs that something is wrong. Now things get interesting. For fans.
