what i'm looking for is what the trigger phrase is. i distinctly remember steve telling it to tony later on in the fic, either as a precaution so tony knows what it is, or as a show of trust. it's driving me crazy. i've tried reading through but it's a long fic and i know i'm accidentally skimming bits in my hurry to find that scene. i'm almost convinced i'm getting this fic mixed up with another similar one.
edit: missbecky has replied and let me know that the scene i'm thinking of (in the second paragraph up there) is not in her fic, so now i'm looking for which fic has this steve-reveals-his-trigger-phrase storyline.
