Inspect the cave

You know the place is long deserted and dangerous, but something urges you to check it out anyways.

You find a lonely kid...what is she doing out here on her own? This is the first live child you have seen since the outbreak.

You return to the lab. The ruined lands are no place for a child. It is safer here. Taking small blood samples from this interesting child, you realize that this is the ingredient you had been looking for.

A cure is not found instantly, no. However, progress is being made. On an up note, having her in the lab reminds you of simpler times, when yours was still around.
