"I've started having my menstrual cycle again," Helen said, biting her lip a bit as she thought it through.

"My cycles were suspended the entire time that I was under the influence of the Source blood, you see, so now I believe I have resumed my normal biological processes. I've also found grey hairs that I didn't have before. Granted, it's not something I can really test, or anything, and my cycles are irregular - I haven't had one every month I've been here - but it's unusual for me."
