What is Sami a symbol of?

The author highlights the journey of Nuri and his wife to Europe to show the brutality refugees are exposed to during evacuation to new countries. After losing their son in an explosion in Syria, Nuri and his wife, alongside other refugees, start a journey to Europe to seek asylum. Refugees travel long distances without food and water to locate new boundaries. After getting to borders, most refugees are denied entry on claims of terrorism, insecurity, lack of visas, among other obstacles. During the journey, Afra is sexually abused by smugglers who aid them in processing passports to enter the UK. Nuri and his wife put up with the sexual assault incident because they do not have an alternative since their primary objective is to find asylum in the UK.
