Last December, stunt performer Heidi Moneymaker (best last name ever) posted pictures on Instagram showing Scarlett Johansson wearing the same clothes and rocking the same hairstyle that she had at the beginning of Captain America: Civil War, when Black Widow and some of the Avengers were in Lagos, Nigeria to apprehend Brock Rumlow, a.k.a. Crossbones. This followed a report months earlier that Frank Grillo had been seen on the Avengers 4 set. So rather than Crossbones being miraculously resurrected, we would be seeing him as he was in Civil War. Finally, we come to the Battle of New York pictures, which originally showed up in January and have been making the rounds again in recent weeks. Some of them shows Chris Evans wearing the same Captain America uniform he had on in The Avengers. Paul Rudd’s Ant-Man and Robert Downey Jr’s Tony Stark were also in the scene, although Tony had blonde-tinted hair and was wearing a S.H.I.E.L.D. jumpsuit. Oh, and there were other pictures showing Mark Ruffalo wearing a motion capture suit and carrying a giant bindle, which is… just weird. In any case, along with Avengers 4‘s present day events, the movie will also be messing around with the past, which leads us to the first theory about how this is possible.
