After SCOTUS declares banning same-sex marriage unconstitutional, Stella (aka fem!Steve) and Peggy are finally married (they'd been refusing to marry until all Americans had the right, even though it was already legal in both dc and new york ). It's big because someone makes the mistake of letting Tony help plan. (Peggy either didn't get Alzheimer's or it was cured because alien tech and/or mind gem, possibly following the headcanon that Hydra somehow poisoned her/ caused her decline )

+10: Bucky (cisswapped or not) watches the wedding from afar, and wholeheartedly approves
+100 AoU compliant, except Pietro is alive.
+1000: non-binary Vision
+over 9000: past Cartinelli. Stella is happy that Peggy was able to find happiness, though she's ofc sad that Peggy lost a second lover
+over infinity: Stella is wearing her Women's Army Corp uniform, Peggy a 1940s-style wedding dres
