Personally I don't think Blakeney and Ruby are a couple and that people may wish they were or are reading into things that just don't exist. Lots of people share beds when travelling and it doesn't mean a thing. Married or non-married, I've slept next to other women and that is it. We chat, we fall asleep. Nothing going on. Maybe it saves on money, maybe we are at a home or on retreat and chose to share for convenience sake, or there simply isn't a choice in the matter. Simple as that. I believe Ruby admires Blakeney, is attached to her to some degree, is amazed to have a friend, but I also think Blakeney, while being a kind and patient person, only feels friendship with Ruby and isn't calling out on the top of her lungs that Ruby is her favourite person or her best friend. She may very well not be, and as Blakeney makes friends throughout her life, possibly marries, has inlaws, co-workers, neighbours, etc., she will find better and more mature friends than Ruby. Ruby has a tremendous amount of maturing to do. I don't think sex even passes through her head, let alone casual dating. More than likely she sees it as a fun way to pretend she is a kid having a sleepover, like Anne Shirley and Diana Barry in Anne of Green Gables, who also shared a bed, or how she used to have sleepovers with her cousins a few times a year. She doesn't seem to know who or what she is or will be, so I think a lot of people are imagining things for the sake of creating more curious content.
