What is the backstory of the character Jimmy, and how does he fit into the John Wick storyline?

Jimmy is a character in the John Wick film series who is played by the actor Thomas Sadoski. He is a police officer who has a small but important role in the first film, and he later reappears in John Wick: Chapter 2.

In the first film, Jimmy is one of the few police officers who is on good terms with John Wick, a legendary hitman who has come out of retirement to seek vengeance for the murder of his dog. Jimmy helps John by providing him with information about the people who have wronged him, and he even looks the other way when John takes care of business.

In John Wick: Chapter 2, Jimmy once again appears as a police officer who is called to the Continental Hotel, a sanctuary for assassins, after John breaks the rules by killing someone on the premises. Jimmy helps John to escape from the hotel, and he even provides him with a gun.

Although Jimmy's role in the John Wick films is relatively small, he is a memorable character who has earned the admiration of fans. His loyalty to John, despite being a police officer, adds an interesting dynamic to the films, and his brief appearances serve as a reminder that even minor characters can play an important role in a larger story.
