Heather wasn't quite sure how to go about this. Seth was just so...happy. How could she ask her if she could stick a needle in her arm just like that? Well, maybe it would actually be easy. If Seth wasn't bothered by the current condition of the city, why would she be bothered by this?
"Well, you know that big monster that's been running loose? Pyramid Head? This...this is part of a ritual to get rid of him. And there are certain people who fall into that ritual based on whether or not they were attacked by him. You weren't, but you still fit in somehow along with a few other people, so now...I need some of your blood." She'd pretty much said it all in one breath, and she hoped it made sense and that Seth would agree to it easily.
