At the age of 20, she followed her brother to New York City five years after Alex moved there to work for Gentek. However she was unable to contact Alex. Alongside her studies, Dana also wrote for a few local tabloids for a living

Days later, she was arrested by Blackwatch due to her relation to Alex. Alex had fled Gentek with a sample of the virus and released it at Penn station. After escaping a morgue, Alex learned about Dana by consuming one of the Blackwatch soldiers and hurried to her apartment. Upon entering the apartment, Alex found his sister being held captive by a soldier. The siblings fled the apartment after he killed the soldier with his bare hands. Dana later revealed to Alex what he had asked her to investigate. When she realized Alex didn't remember his past, she helped him discover what had happened to him
