Tony's practically become an old hat at being taken hostage, but something's fishier than usual this time around: his captor looks twenty-eight but claims to know Howard Stark, the NYPD negotiator is a SHIELD plant, and what's this about a fleet of helicarriers set to launch? (TWS AU.)
Tony is smart in this fic, figuring out how to handle the Winter Soldier and uncovering the reality of his situation all at once. This is an entire mystery plot and recovery story, set in a single conference room over the course of only a few hours. Masterfully concise and well-characterized.
Spot On - Tony Stark is all chatter, the Winter Soldier all silence, and yet it's crystal clear how their relationship slowly solidifies.
