POP.Mylene visits her old mentor Mr. Ironheart who has gone AWOL. He infiltrated Dr. Green's Eastern bloc Supernatural Power Research Facility three months earlier, but failed to return with the data. When she finds him they reminisce about their old missions together when she was still a rookie spy and he used "pop" as his keyword to trigger his explosives. He explains that when he infiltrated the facility, he found that Dr. Etcetera had died while investigating a drug for use on mutant children to accelerate their mental abilities, but which resulted in their deaths. Ironheart was overcome by the naive creativity of the children, and Etcetera's assistant gave him the only drug samples. However, Ironheart considers that he failed his mission because he became emotionally involved. Suddenly, they are surrounded by East bloc soldiers so Ironheart acts as a decoy to enable Mylene to escape. She then explodes a bomb to destroy both him and the soldiers, using his old keyword, "pop".
