Captain America got his happy ending in Avengers: Endgame, but his fate actually created a secret tragedy elsewhere in the MCUs Infinity Saga. Fans were already prepared for Endgame to be Chris Evans last appearance as Steve Rogers, so the major uncertainty was whether the hero would make it out of the Infinity Saga unscathed. Steve survived the Battle of Earth, but his ending was still bittersweet as fans lost the MCUs main variant of Captain America.

On his journey back in time to put back the Infinity Stones, Steve decided to stay in the past and live out life with Peggy Carter while an aged version of him appeared in the present day. Ever since his debut in Captain America: The First Avenger, the two had a tragic romance that never worked out timing-wise. Although it meant that the MCUs Steve was undoubtedly retired, seeing the two happy together felt rewarding.
