Not sure if this is the place to post, but I've seen lots of people mention theories on the darkness and how it may have it's own guardians. I was wondering if the exo stranger was maybe one of those darkness guardians. When we first meet her in person and dinklebot says "you're not a guardian." She replies , "no, I was not born of light." I thought it very interesting her choice in wording. That's literally my only basis for the idea though, but something I thought to throw in.
