Tony begins to notice that things are going missing from his workshop... and discovers that his bots have been hiding a very, very big secret from him. Or rather, a very, very small one. In which Dummy is a kleptomaniac, You is painfully shy, Butterfingers is a programming genius, JARVIS is a sarcastic sonofabitch, Pepper takes care of Tony outside of the workshop, Bruce is Tony's boo, Thor is Tony's favourite, Clint is actually kind of smart, Steve has terrible timing, and problem-solving is never simple or easy.

Taking care of Tony is a lot of work. Especially when you’ve only got one arm. And your code dates back to the 1980s.

Extremis has a few unexpected benefits.

"When Tony is pinned down, armourless, in a workshop during an assault on Stark/Avengers Tower, Clint is meant to be the cavalry. When he arrives, though, he finds that the enemy may have picked the wrong workshop to try and take Tony in. JARVIS, it turns out, really doesn't take prisoners. Author's Note: Clint and Tony, Tony and his babies, basically. Came out ... rather darker and more violent than I anticipated -_-; No, seriously. VIOLENT."

"When Tony Stark was seventeen years old, he built his first AI. On that day, he ceased to be his father's creation, and became a creating force in his own right. That one act likely saved his life, and not always in the most obvious ways."
