AN: Human and teenager AU, eventual Tony/Bruce (My OTP for Avengers, closely followed by Clintasha). Yes, I love Avengers so much that I'd probably spontaneously combust if I owned them. (:D So much for my dislike of long words that comes up when I'm in a writing mood)

It was a loud party. The penthouse of Howard Stark's tower was full to the brim with guests. Pretty waitresses were walking around with drinks on trays.

Normally Anthony Stark would be in the center of such a party, taking advantage of the fact that his mother was not telling him to not have any alcohol. But Howard Stark's fifteen-year-old son was not enjoying his birthday celebrations. He had told his father that he didn't want a massive party thrown, (though he did love parties) he wanted to work on something with his father in the slightly scary technology lab Howard often blew things up in.

So, Tony was sulking. He hadn't gone into the party at all, though he had sent Jarvis to get him some food because he was hungry, but he had left it sitting on his desk, because he'd decided he wasn't hungry at all.

Tony had sat in his bedroom all night, sitting in a chair that faced out onto his balcony. He would have been out there watching the city, but it was raining really heavily, and Tony didn't fancy getting wet. So he just sat there watching the rain blur the lights of the city below him.

And there, in the darkness, something moved on his balcony. Tony stood up to check it out.

And there, hugging his body to the wall as closely as Tony thought was humanly possible, was a boy about his age. He was soaking wet and Tony had no idea how he had not spotted the boy before.

Not thinking, he opened the door to his balcony, and the boy's head snapped up. Tony grimaced as he immediately got soaked with the rain. The boy opened his mouth to say something, and Tony shook his head. "Get your stupid ass inside." He said, and the boy flinched but obliged.

The boy hurried inside. The moment Tony shut the door, he started spluttering an apology. His dark shirt and trousers were almost see-through with rain, and his semi-long dark brown hair masked his face. "Save it." Tony said. "Tell me your name and why the hell you were out in that storm."

The boy appeared to get even smaller, shrinking down even though he and Tony were still standing. "B-b-bruce Banner." He stuttered. "I r-ran."
