Subduing them, he has a message he wants them to deliver to their leader King Cobra—but Cobra is right behind him, with others of the Society.

At Baron Zemo’s castle, Cap is aided in the mopping up operations by the Avengers. Finding a note from Diamondback announcing she is going away, he questions Black Widow about it and learns of Rachel’s fear that she is not worthy of Steve. Needing to think things over, Cap stays behind as the Avengers leave with the kidnapped children. Free Spirit asks him for a favor: can he teach her to fight, for her next confrontation with her enemy Dr. Wentworth/Superia? Cap agrees, wondering if she will have to replace him soon.
We learn the origin of Jack Flag: he and his brother Drake were members of Captain America’s Computer Hotline Network and started a citizen’s patrol group in their Arizona hometown—until thugs caught Drake alone and crippled him. Shortly afterward, their parents were cheated out of their home and life’s savings by a company which turned out to be a front for the Serpent Society. So Jack trained in the martial arts and Drake built him an arsenal including the Boom Box and now he is out for revenge against the Serpents. Except that now he is their prisoner. Insisting he wants to join up, Cobra sets a test for him: steal a painting from an enemy in Reno and bring it back to him, and Jack can join the Society. Jack is dropped off in Reno—and Cobra makes a call to the homeowner: Mr. Hyde. Three hours later, Jack breaks into the house—and is caught by the huge brutish bad guy and hurled into a table of chemicals. He manages to toss acid in Hyde’s eyes and leap from a window. Calling the Hotline he summons help and drags himself away. He collapses some blocks away and is found by an angry Hyde who intends to make him suffer. Jack boxes Hyde’s ears and flees, realizing that the chemicals he was soaked with have increased his strength and healing ability….
