You were one of the few Racoon City survivors, escaping mere hours before the city was inevitably bombed and wiped out forever.
On your journey to escaping city, you had found a young child who seemed to be all on her own - seeing as you couldn't just leave her there you took her with you and got her out too. Now, it was all over.. it was a miracle you had both managed to survive but here you were.
It had taken a while, but you brought her back to your home without anybody knowing.. her parents didn't seem to be in the picture anymore so what else could you do? She had gone around to get used to the new place, and she seemed content where she was.
Now she was sitting in your living room, watching a channel on the TV. Maybe you could check in with her? After all, she was your responsibility now and for the time being.
