Nick Fury is finishing a line about why SHIELD used the tesseract to create weapons.  He is seen through a darkened transparent screen showing the designs of these weapons, representing the darkened way the other heroes now see him.  After Thor comments, Fury states that “the world’s filling up with people who can’t be… controlled.”  Although these are SHIELD’s views and not Fury’s own, they parallel Loki’s mission to rule humanity to control them.  As the Avengers begin to argue, the camera begins to quickly pan between them, creating a temporary blur with a dizzying effect.  When Stark sarcastically remarks that “a nuclear deterrent… always calms everything right down,” Fury’s retort, which points out that Stark’s money came from selling weaponry, suggests that Fury believes Stark is a hypocrite for passing himself as a hero when his technology has taken so many lives.  Captain America makes a jab at Stark, implying he is selfish, and the camera passes directly between them, suggesting a rift forming between the two.  The camera again begins to shift in a disorienting manner between the Avengers as their argument grows, zooming in first on Thor, then Natasha, and finally Banner, but each on the far left edge of the frame.  After passing each one of them, the argument becomes unintelligible, and the camera zooms in on the glowing gem at the head of Loki’s spear and flips over, showing the Avengers arguing from an upside-down perspective.  The disorientation of this series of shots followed by the focus on the gem in Loki’s spear reveals the manipulating effect Loki has had on the group to cause them to break apart from the inside.
