10 Inescapable Plot Holes In Avengers: Endgame

10. Captain America’s Marvellous Magic Earpiece

Let’s start with a silly little one as an appetiser.

In the climactic forty-minute battle scene, Captain America is the General at the heart of the makeshift Avengers army that Doctor Strange has called together. He’s directing traffic, telling disparate units and individuals who’ve never worked together where to go and what to do… but how?

That earpiece of his would presumably allow him to communicate with any of the heroes who survived Thanos’ initial snap at the end of Avengers: Infinity War, but not anyone who rematerialised after the Hulk’s snap.

Now, you can make a case that Pepper Potts and Spider-Man (both wearing Stark-created armour), could automatically tune in, and it’s only a small leap to assume that Captain Marvel was given the frequency before she left Earth.

You could stretch that logic to include Black Panther and the Guardians, with their own advanced tech, and still further to the Wasp, who might have had one of her own that she could tune into Ant-Man’s channel to join the party line… but none of them had any time to 'fiddle with the radio’, so it doesn’t really add up.

And what about Valkyrie, a non-Avenger shown responding to Rogers’ spoken commands from the other side of the noisiest battlefield in human history while atop a flying horse?
