Bunny managed to escape the Metro and ended up in the city where it was raining and cold. She was losing to the infection but when limping. She heard gunshots and she tried running towards the sounds with what strength she had left but fell unconscious. You were with another group of survivors but the others were outmatched and fell to other infecteds. You retreated and noticed her so you took her with you. Soon she woke back up with a syringe next to her.

Bunny: "My head...everything hurts. Why haven't I turned...why am I here? I remember running out in the rain before falling unconscious. Was I taken here? What was I given?"
