They All Fall Down
Prologue:
Two men walked to the entrance of Stark Tower. The 6'3" blonde with a fairly muscular build and a determined look upon his features strode to the entrance. The other, a 5'11" man with shaggy brown hair and a slightly lanky build, shuffled behind him, regretfully. They stopped at the door when the brown haired man spoke up for the first time.
"Are you sure we should be doing this? I mean, this is Iron Man, he saved the city more than once."
The blonde haired man looked back at him, exasperated by his partner. "Shut up! I know that already! I'm just following orders and you should be too!" He turned back to the door, pushing it open with more force than necessary.
"It would help if I knew what the hell I'm supposed to be doing!" retorted the shorter man, almost being hit by the door swinging back.
"God, are you really that stupid?" asked the blonde, "Stark. He lives here with the rest of the avengers."
"Yes, but what does that have to do with a package?" inquired the brunette.
"Let me finish you dimwit! Right, so remember yesterday? How we got these uniforms in the first place?" The taller man was getting slightly annoyed by the other, raising his voice unintentionally.
"Yeah, we broke into the Post Office and stole these, as well as a package for Tony Stark, which you still haven't told me why it's so important!" The shorter man retorted. He just couldn't figure this out. What were they doing?
"Sometimes I wonder how the boss even hired someone like you…" Thank god they were only working together this once…
"Just tell me what the fucking plan is!" The shorter man wasn't stupid. He just wasn't well informed. All he knew was that whoever hired them wanted to harm the Avengers, specifically Tony Stark.
"We got the package. A shipment from New Mexico Chemical Supply Co. We took his innocent little chemicals and replaced them with two highly reactive, very dangerous chemicals. So, next time Stark wants to make a little poison arrow for Hawkeye, or a sedative for the Hulk… BOOM goes the Avengers" The blonde didn't look particularly happy about this fact, just doing his job.
They had reached the desk, and immediately stopped talking, handing the package to a fairly hot, young, blonde woman, talking through her Bluetooth. She looked up and smiled at them before they turned around and exited the building. The blonde pulled a phone out of his pocket, hitting speed dial 2. He waited for only one ring before someone picked up. "Mission Accomplished."
"And now, we wait."
