So, I love prompts where Steve and/or Bucky "jump on the grenade" for someone, but I'd like to see Nat doing so. Maybe she and Wanda get captured during the time before IW, or maybe she is protecting one of the weaker girls in the Red Room from going on a honeypot mission because the guy is a total sadist. I'm not picky about details, just the thought of Nat trying to protect someone because she thinks she is better equipped to deal with the rape due to her training + especially if it's Wanda, the thought of not letting her "lose her innocence" like that.
