Stark's Board of Directors presents Tony with the copmany's latest invention: the world's most advanced cellular phone, capable among other things to connect to the Internet anywhere in the world (using Stark's Zipsat satellite constellation). Tony Stark tells them to make money from that phone, and desist from looking military contracts.
Tony arrives at Futurepharm where his friend Dr. Maya Hasen explains that her project director (who killed himself in the previous issue) stole a dose of Extremis and gave it to an unknown. Tony uses his new phone to send data from the burglar scientist's PC to be analyzed, and takes Maya to a common friend called Sal to cheer her up. But Sal doesn't really do that.
Meanwhile, Madden Mallen enters the Houston FBI division, kills police, and civilians, and destroys parts of the building. He's practically invulnerable to bullets, has tremendous strength, and can throw fire from his throat.
When Maya and Stark watch the live CNN coverage on his phone, she realizes that the one responsible is whoever took the Extremis dose.
