Sun's mural in the prison-yard is splashed by another inmate with red paint. During the ensuing brawl the stains on the painting change positions multiple times.
While Nomi is attempting to escape the police, Sun appears and says, "I'm in Seoul. I was sleeping." However, the translated print on the back of Sun's prison fatigues gives the name of the prison as Southern Cheongju Women's Prison. The city of Cheongju is two provinces away from Seoul, 66 miles (107 km) to the south-southeast.
