Thomas was born in an urban city and had a few friends and used to play a lot of video games, especially shooters. After failing the college entrance exam he started studying by himself since he finished school. His family was pressuring him to not fail the other year (in Brazil, there is one exam per year), and his cousin invited Tom to go on a trip to Russia. He accepted without thinking twice, because of all the stress he was going through.
3 weeks before the infection, Thomas and his cousin went Russia, and they hopped onto a train inbound for Chernarus to meet a College professor who taught them chernorussian culture and food... When the bombing started from the Russians on the military base. Soon the government locked down the country and prevented any one from leaving to prevent the spread of the virus. They got hosted on a Chernogorks motel and spent their time there until all the infected showed up. And made Tom go on his own.
