10 MCU Moments More Important Than You Realised

The MCU sometimes brings back minor side characters years after we last saw them (like the "I'm not Tony Stark" guy from Iron Man returning in Spider-Man: Far From Home), and though not many people realised it, the franchise did something similar with a small moment in Captain America: The Winter Soldier.

Towards the end of Cap's second solo outing, there's a scene where HYDRA agent Brock Rumlow holds a SHIELD technician at gunpoint, forcing him to launch the Project Insight Helicarriers.

This technician refuses and a scuffle quickly breaks out, and though the Helicarriers are ultimately launched by Rumlow himself, this random SHIELD member's courageous display is later rewarded when Nick Fury recruits him to his inner circle.

The technician's proper name is Cameron Klein, and in a moment that a good deal of viewers probably didn't register, he returns in Avengers: Age Of Ultron, assisting Fury and Maria Hill in rescuing the citizens of Sokovia.

The MCU does world-building better than any other franchise, and thoughtful continuity details like this are a big reason why.
