The last time we saw Sam Wilson in Avengers: Endgame, his story had shifted monumentally. After Thanos was defeated, Steve Rogers returned the Infinity Stones to their timelines. He also returned in his 100s, having been happily married to his long lost love for decades, to pass the Shield to Wilson. While Bucky Barnes had worked on his trauma as The Winter Soldier, he could continue starting over. Not much else was known about their future except that they were meant to work, fight, and annoy each other to our delight in their own Disney+ series.
But one question stuck in the back of mind - What happens when you already know the endgame?
Spoilers for the Marvel Cinematic Universe including Agent Carter, the general Marvel Cinematic Universe, and The Falcon and the Winter Soldier are below. I'm sorry it's another long-ass post. This is just another example of my writing meltdown. Skip to the 'Basically' part at the end if you want. Otherwise, *Cap salute*.
