Tony as a competent TA

[marsmaywander.livejournal.com]

age-old story. passed over a fic in AO3, then hours later i want to read it and can't find it. i remember that either the summary or the bookmarker's comments were talking about how many of the college!au tropes had tony as an impatient jerk of a TA who talked over the heads of his students, but that they wanted to see tony as a highly effective TA that taught people well (since you have to know the subject really well in order to teach it properly).

so basically, looking for a fic with tony as a TA who's good at teaching (or recs, if i can't get the exact fic). ringing any bells? super appreciated!

*found - Specific Steve/Tony Fic Search

Okay, this is a long shot because I can only really remember a small piece of one specific scene.

Tony is in his workshop and Steve comes down. The part that I remember is Tony watching as Steve punches his pass code in and musing about how quickly he always does it like he's afraid he has to do it quickly or it won't work or something. And how no matter how fast he punches it in, he always gets the code right.

Yeah, almost nothing to go on, sorry.

I can tell you that it was definitely Steve/Tony (could have been pre-slash) and that it was definitely on Ao3. I think it was probably over 10K. I know those things simply because my only Avengers reading has been on Ao3 and in the steve/tony tag and that I always use the word count filter and I haven't made it down into the smaller word counts yet.

This is kind of a last ditch effort on my part to find this fic because that particular scene keeps scratching at the back of my mind and I'd really like to fill in the blanks again. Thanks!

(I honestly can't be any more specific on the tags since I remember so little from the fic itself. :x sorry)
