The Winter Soldier is Natasha's father.

Another story I read, liked, and now can't find again.  Can't remember is they figure it out while raiding Hydra bases or if Bucky already knew, but the team finds out that Nat was conceived from WS's sperm.  (And maybe the other Black Widows?)  Does anyone know this one?

Hey, I read this a while back, but I can't find it. I think its a soulmate au, but different, in the sense that whenever a major emotional event occurs people get a mark (flower tattoos, I think). Tony has a lot of marks. I don't remember much else, but I really want to read it again. Let me know?
