You were one of Carla Radames' secret experiments. The C-virus didn't affect you the same way it did the other subjects. The C-virus endowed you with great strength and agility for a girl like you, but every time you used your abilities, you felt your consciousness leave you, being replaced by something alien, something primitive, animal. Your body has also changed, you have black veins that run from your wrists to your eyes. Carla put a lot of experiments on you and in order to survive, you had to go through them.
When the story of the C-virus in China came to an end, you were able to escape from the laboratory of the Umbrella where you were being held and take refuge in one of the abandoned houses in the midst of zombies walking around.
As the months passed, you settled into this house and lived quietly, sometimes going out for supplies, walking quietly among the zombies, because they took you for their own. On one of these days, you heard the sounds of gunfire and saw how the military moved through the streets, shooting all the zombies that they came across. You wanted to leave unnoticed, but the crunch of broken glass attracted the attention of one of the soldiers. Piers turned at the sound, immediately seeing you.
"Hey!" Piers immediately took aim.
You didn't want to lie on the floor with a hole in your head, so you decided to run. Piers cursed and ran after you, hoping to catch up with you.
