<p>I think there's a Civil War reference in Endgame.</p><p>So you know in the Battle of Earth where Black Panther takes the Infinity Gauntlet from Clint? He says, "Clint!" to get his attention. I was thinking this could've been a reference from Captain America: Civil War where they're fighting and Clint says, "I'm Clint." and then T'Challa responds with, "I don't care." But in Endgame, he remembers Clint's name because he calls out his name to get his attention. And this happened like 8 years after Clint said that his name was Clint. If T'Challa remembered Clint's name after so long, he really did care about Clint's name! Basically this is a reference/contradiction to Civil War.</p>
