Who is the character D'Antonio's bodyguard, Charlie, and how does he fit into the John Wick storyline?

In the John Wick universe, Charlie is the loyal bodyguard of Santino D'Antonio, an influential member of the High Table, the council of powerful crime lords. He is first introduced in John Wick: Chapter 2 as a formidable opponent, skilled in combat and loyal to his employer, D'Antonio. Charlie is played by British actor, David Patrick Kelly.

Charlie's role in the storyline is crucial as he acts as a protector for D'Antonio, and his actions ultimately contribute to the film's plot. Charlie is involved in the assassination attempt on John Wick in the Catacombs of Rome, where he battles John Wick and ultimately meets his demise.

While Charlie's screen time is limited, his character's contribution to the plot is significant. He is a classic example of a henchman character who serves to further the main villain's goals and provide a physical challenge to the protagonist.
