If it's not too late, I'd love any kind of commentary on Sucker Punch. I read that story a few years ago and it still haunts me.
Oh boy! This one was for a Cap-IM community prompt asking for a fic where Steve only finds out Tony's identity when he shatters Tony's faceplate at the end of Civil War, and I thought this was a great idea for angst and I was talking about it with, honestly, probably Kiyaar, and then it occurred to me that I could make it a lot worse if Steve in this story had actually never liked Tony much at all. Which is of course completely unlike canon, but then it gives you the opportunity to have identity porn where Steve talks shit about Tony to Iron Man, and then Steve finds out that Iron Man, whom he loves, is actually Tony, who he doesn't.
Then it occurred to me that all of Steve and Tony's canonical fights would be so much worse with identity porn, because pretty much all their major fights (not just Civil War) happen without identity porn, when Steve knows who Tony is. But if Steve doesn't know Tony is Iron Man, then he thinks that Tony and Iron Man are separate people. And, say, for Armor Wars -- he knows Tony is the guy who wants his tech back, but Iron Man is the guy he actually fights. So he probably thinks Tony puts Iron Man up to it, and that's going to decrease his opinion of Tony even more. So the actual fic was basically me speedrunning through every argument they ever had (I reread a whole bunch of comics very fast) and then deciding that for Maximum Angst Steve should actually ask Iron Man who he is and make this be the one thing he would switch sides in Civil War for -- since Tony canonically publicly reveals his identity for CW, it'd be even more hypocritical of him to be pro-Reg and keep his identity a secret. And of course, by this point, Tony is the one person that Steve least wants Iron Man to be, and Tony knows this, and so he doesn't tell him.
(I imagine that from Tony's POV this would be even more fucked up because he knows Steve hates him and yet he can't make himself walk away because he also knows Steve loves Iron Man. I think it goes well with Tony's history of shitty relationships.)
I think this is the one sad Steve/Tony story I've ever written that I don't think I could fix, and I include in this comparison stories where they're both dead at the end. I don't think I can make it better when Steve just... hates Tony right from the beginning.
