Wow, that is definitely not how I expected her to be made part of the canon. When I saw Galaxy's Edge in the link, I assumed it was going to be one of the books or the comic.
I don't know if anyone is planning on watching it, but the Galaxy's Edge Freeform special is on tonight. I would watch it, but it's on at the same time as the NCIS: LA season premier, and that's one of my favorite shows, and definitely takes priority.
