What is the role of the character Zero's henchwoman, the ballet dancer, in John Wick: Chapter 3 - Parabellum?

The character in question is known as 'Ernest' or 'Earnest' and is played by the Russian ballerina and choreographer, Unity Phelan. She is Zero's henchwoman and appears in several action scenes throughout the movie.

Ernest is first introduced in the movie during the ballet sequence at the beginning of the film. She catches John Wick's eye during the performance, and later appears to have been hired by Zero to help him capture Wick. She is an accomplished fighter and uses her ballet training to her advantage during fight scenes. In one memorable scene, she even uses her pointe shoes to attack Wick.

While not a major character in the movie, Ernest is an important part of Zero's team and plays a significant role in the action sequences. Her ballet skills and graceful movements make for some visually stunning fight scenes.

The character Zero's henchwoman, the ballet dancer, is a young woman who is training to be an assassin. She is seen in two scenes in the film, first dancing for Angelica Huston's character, The Director, and then fighting John Wick in the Continental Hotel.

In the first scene, the ballet dancer is shown to be a skilled dancer with a great deal of grace and athleticism. She is also shown to be very beautiful, which is likely why The Director has chosen her to be her henchwoman.

In the second scene, the ballet dancer fights John Wick in the Continental Hotel. She is shown to be a very skilled fighter, and she gives John Wick a run for his money. However, in the end, John Wick is victorious.

The ballet dancer's role in the film is to show the audience that even the most innocent-looking people can be dangerous. She is also a reminder that John Wick is not the only skilled fighter in the world.

The ballet dancer is played by Unity Phelan, a real-life ballet dancer who is a principal dancer with the New York City Ballet. Phelan's performance in the film was praised by critics, who noted her grace, athleticism, and beauty.

The ballet dancer is a minor character in John Wick: Chapter 3 - Parabellum, but she makes a significant impact. She is a reminder that even the most innocent-looking people can be dangerous, and she shows the audience that John Wick is not the only skilled fighter in the world.
