Race for a Cure (Bruce, Annie & Tony)
He was uptown when one of the massive canisters exploded overhead. Bruce instinctively flinched at the sound, looking up towards the sky as burning bits of metal and gas came raining down, thick and heavy. For a moment, he could only stare up, like everyone else on the street, towards the smokey cloud as it fell to the Earth. Already the air was growing smokey, and Bruce could feel his eyes starting to burn. Stifling a cough, he turned to run, only to have a piece of the aerosol container hit the ground in front of him. Bruce yelped in surprise and quickly took a step back, then crouched to inspect the thing. Even from where he sat, he could feel the heat radiating off of the debris, but he didn't need to be any closer to it than he was already was to see the letters stamped in red on the metal, even as the heat peeled them away.
It didn't take a genius to work out the rest.
Bruce ran. Pulling down his sleeve, he clapped one hand over his mouth and used the cloth as something of a barrier to prevent himself inhaling whatever toxic concoction was raining down from the heavens. He looked around only briefly, silently apologizing to the men, women and children around him as the gas overtook them. He couldn't do anything for them now, as much as it pained him to admit it.
He sprinted down the streets of Manhattan, forcing his way through crowds of people and dodging through lanes of traffic. The only things on his mind were staying ahead of the gas, and making it to the Oscorp facilities. Without having to think about it, he found himself reaching for the phone Tony had given him and pressing the Emergency Contacts button.
"JARVIS! Get me through to the labs, now, or wherever the hell Tony is! There's something-" he coughed, made a face, and narrowly avoided being hit by a bus. "S-something happening... Put me through to one of the scientists, or Tony, or whoever you can find! I'll be at the tower in five, maybe ten minutes, okay?"
