Searching for Tony fic

[ladyharuna.livejournal.com]

I barely remember the fic but I do know it here were a few notable items in it
1). Tony used various metals as code words to indicate his safety with Jarvis.
2). Tony had been kidnapped and arranged his own escape while the rest of the team complained that he was out of reach. He never told them what happened to him but the team found out. Steve ends up killing one of the guys in an interrogation room.
3). Happy has know Tony since Canada, where when he was younger Tony was going thru chemo. He knows the metal code words.
4). Tony never gave Jarvis limits, just asked Jarvis to tell him up front if he was going to betray him.

Please help me find this Awesome Fic!
