I'm looking for a fic, where Dummy was perfectly capable of doing whatever the task he was given, but once he was doing them for Tony, he screwed everything up. Bruce explained, that Tony was making Dummy nervous, because he created him and the bot wanted to impress him.
I read this fic a long time ago and I wanted to read it again, but I can't find it :(
It probably was on FanFiction.Net (though LiveJournal is a possibility, too) and most likely had Tony Stark and Bruce Banner as the main characters.
I would really appreciate it, if you could help me find this fic.
