1) Captain America No More
The end of the film hints that Steve Rogers might be about to retire from being Captain America, as he discards his famous shield while rescuing his friends from the Raft.
This is a multi-layered easter egg. Firstly, it is a way of mirroring the demise of Captain America in the original Civil War comic without killing Rogers off. It’s also a reference to the several times throughout the character’s history where he’s given up his patriotic alter ego. In those times, he has gone by the titles The Captain or Nomad, instead.
[zergpaid]Cap and his team now operating as fugitives also reflects the fallout of the comic, which saw Tony lead the officially-sanctioned Mighty Avengers while the likes of Luke Cage, Spider-Woman and Wolverine formed the breakaway group, calling themselves the New Avengers.
We’ll probably have to wait until Avengers: Infinity War to see how long our heroes stay separated for in the movies, but we can’t imagine it will be for long.
