Julius is the rich man who dates Auntie Sonia. He frequently totes a baseball bat, which he calls “the Persuader,” and physically abuses Auntie Sonia, who eventually flees the country to escape from him. At one point, Lydia reveals to Harri that Julius sells fake visas, which is why he’s so wealthy. Given that Mamma frequently gives Julius money, the implication is that Harri’s family’s visa is also fake.
