I wrote a couple very short stories for
trickortreatex! Both MCU, because that's just how I roll right now, I guess.
First,
A Worthy Foe, about Natasha and Pepper: Pepper confronts Natalie Rushman about her true identity, and the two of them come to a tentative alliance.
Second,
Nightmare, which is about post-TWS Bucky watching Steve through his bedroom window like a creeper. Steve has a nightmare. Bucky is concerned.
