At the climax of the Avengers saga, the heroes must get the Infinity stones from Thanos. Captain America orders Ant-Man and the Wasp to get started on part of the plan, and both of them respond with, “We’re on it, Cap.” They grin and get to work.
This is a reference to Wasp mocking Scott Lang for referring to Captain America as “Cap” in the movie “Ant-Man and the Wasp,” wondering if they’re friends now just because they fought on the same battlefield. By the time of Endgame, it doesn’t matter – just get the job done and call people what makes the most sense.
Not Strong Enough
The Black Panther suit uses vibration to store and release the kinetic energy that strikes it. Not only does this protect the wearer, but it gives the wearer a powerful weapon to strike back at foes. However, if a foe is too strong – like Thanos, for instance – it can overload the suit and explode.
We see this happen during the hectic and frantic fight at the end of “Avengers: Infinity War,” which has T'Challa going up against the mad titan with everything he can muster. It doesn't work, the suit explodes, and T'Challa is taken out of the fight.
The Killing Blow
Thanos is confident in himself, that's for sure. He always thinks he's going to win, no matter what, which is one of the reasons why he tells Thor that the god of thunder would have to strike Thanos in the head to finish him. Thor does so at the start of “Avengers: Endgame” to kill Thanos.
Then, when the past version shows up to stop their meddling, Thor keeps trying to strike Thanos in the head, but he is never able to connect. He keeps missing, or something gets in the way, eventually leading to Tony Stark having to steal the Infinity stones.
Shoutout to Shawarma
We all know that the Avengers grabbed a little bit of lunch after defeating Loki and stopping an alien invasion in “The Avengers,” so including it as a reference made perfect sense once time travel got thrown into the mix. We get to see a little more of what happened between the battle and the lunch.
For instance, the Avengers get to meet a guy named Alexander Pierce. He asks them where they think they're going, and Thor answers that they're going to “get a bit of lunch” and then take Loki to Asgard. Plenty of people realized “a bit of lunch” meant shawarma.
Who Is Stan Lee?
Of course, in the real world, Stan Lee is the creator of many of the on-screen heroes that have been wowing us ever since “Iron Man.” But what is he in the Marvel Cinematic Universe? He has a cameo in almost every movie, appearing as both himself and other characters. Well, his cameo in “Guardians of the Galaxy vol. 2” seems to shed some light on it.
The Watchers are an alien species that can see entire universes. He's spotted telling the watchers about the stuff that happened in the other MCU movies, which means he might be one of them. Or an independent contractor.
