Who is the character Winston's ally, Aurelio, and how does he fit into the John Wick storyline?

Aurelio is a character in the John Wick franchise and a close ally of Winston, who is the manager of the Continental hotel. Aurelio is portrayed by actor John Leguizamo in the first two movies of the series.

In the first movie, Aurelio is the owner of a chop shop that works on John Wick's stolen car. After learning that the car belongs to Wick, Aurelio immediately stops working on it and returns it to him without charge. This act of kindness establishes Aurelio as an ally of Wick and leads to a friendship between the two characters.

In the second movie, Aurelio's role is expanded upon. When Wick is being hunted by the other assassins, he seeks refuge with Aurelio, who helps him obtain weapons and prepare for his fight. Aurelio's character demonstrates loyalty to Wick and his willingness to help him in his fight against those who betrayed him.

Aurelio is an important character in the John Wick storyline, as he is one of the few people that Wick trusts and can rely on. He also provides a sense of humanity and compassion in an otherwise ruthless world of assassins and criminals.
