Real people with real blood trumped hypothetical ones, and, not that Tony would admit it, he wasn't looking forward to meeting the talkative guy in the stairwell. They had lured the thing up here, after all, and he might be able to get back and scope out the entire building before it found its next target. If it was him in there, anyway, he wouldn't be making a lot of noise.
"Up, quick," he instructed Noriko, beckoning to her in case she couldn't hear and demonstrating by turning his back and crouching in preparation of her inconsequential weight. He would need his arms for his slightly less experienced, possibly unstable cargo, whether Ben wanted it or not. Just as Iron Man felt Noriko grab him, the mutant zombie launched itself against the far wall of the roof access shelter and its hungry gaze locked right onto Iron Man's glow. Tony exclaimed in surprise but didn't take the time to apologize for the language before snatching Ben around the waist and kicking off of the concrete, snapping him up into the air just in time for his dangling foot to knock into the mutant's angrily wrinkled forehead. In its fury, it screamed and leapt at them like a tiny goddamn Hulk, and Iron Man, in more desperation than fury with his arms otherwise occupied, reacted by kicking a repulsor blast in its face. The zombie dropped, but so did Iron Man and his two passengers for a terrifying moment until he switched back into a steady flight jet.
