Staring off with a vid:
Bad Romance: Dottie/Peggy being best enemies with UST to a song made for them. The way they mirror each other was never clearer, or more musical fun.
Out of the Cave follow-up on Whitney Frost that doesn't ignore what happened to her and takes it into account but also provides her with a new beginning as Dottie, for reasons of A Cunning Plan, teams up with her. I'd watch that episode - or spin-off!
Not your fairytale princess: Dottie and Peggy (do we sense a theme here?) being their frenemy selves. All the writers manage to get Dottie so well because they don't downplay how dangerous she is, obsession with Peggy not withstanding.
Redacted: Four kisses from Dottie that never made it in Peggy's reports. This one spans decades, and the last one is heartbreaking in the best way.
Four times Peggy tried to run away (and the one time it finally worked): Peggy and her brother Michael. I have a soft spot for sibling dynamics, and this is a beautiful take on them.
Teamwork Peggy and Jarvis fighting crime together was by far my favourite aspect of Agent Carter, and the story captures their dynamic exactly. Love it!
Like a house on fire: more of the original Jarvis, this time exploring his take on Howard. (With plenty of Peggy as well.) Funny and touching in turns.
Rose in the Spring Rose Roberts between seasons 1 and 2. The bigger role Rose had in s2 was such a delightful surprise, and this story additionally fleshes her out.
My own story is, I think, a bit less obvious than usual, but still guessable.
