László's relationship with his wife, Erzsébet, is one of the most important aspects of The Brutalist. Despite the marital issues that they face throughout the course of the film, László clearly loves Erzsébet. After being separated during World War II and sent to different concentration camps, László is forced to immigrate to America alone. Because of this, Erzsébet doesn't show up until the second half of the movie. Despite this, Erzsébet is still one of the best characters in The Brutalist, and represents the themes that the film explores perfectly.
