So hey y'all, I figured a good example of a knight was found hidden in a movie most of us have seen...the Avengers.

The knight is the one, the only, Phil Colson. Agent Colson.

That's right, Agent Colson fulfills many roles related to knights in the movie, from the unifier (his death helping to unify the Avengers) to the voice of encouragement ("I think we may need old-fashioned.") To ultimately his bravery and wit in fighting Loki. He was not going to win that battle, but he still attacked an evil oppnent far greater than he was, giving the  others a chance to either escape or fight back against the chaos around them.

This man with no powers, nothing exemptional, except his belief in good and his bravery in the face of evil.
