1.) six and the pretender are sisters -for the longest time now I stuck with the whole, The Hunter and The Lady were the biological parents of six bc it just felt right, how her personality and physical traits just blend really well as the offspring of the lady and the hunter but the more that I look at it, I feel like The Lady and The thin man, a very common ship, could have happened. there is a tv in the maw, meaning that there is a way that the thin man could in theory could have visited the lady, or at least had contact with her, which could lead to 'more'. here's where the pretender comes in, she's the off spring of the Thin man and Teacher, how and why? well ya see, in very little nightmares, the mobile game, there's a picture in one of the halls of two adults standing beside the pretender, people have theorized that the the one adult on the left is the thin man due to the long gray pants and shoes, and the adult on the right is the teacher due to the, again, she shoes, and the long, plain, skirt

2.) mono and rcg are siblings -I honestly just thought they shared the same appearances, dark brown curly hair, somewhat same skin tone, and height that's honestly it.

3.)shadow six and rcg are the same person -this is a bit of a stretch, but uh- here we go, this will be a long one. I suspect the raincoat was like some sort of lock, as if once rcg died in it she was now physically attached to it and once sic put on the raincoat, rcg was now with her, I suspect the way rcg truly became shadow six was when the thin man got a hold of six and the raincoat , the thin man not only twisted six into a monster, but as well rcg as well , into a darker version, also It could be a that rcg is and somewhat will always be in six's shadow, sure she's the original owner of the yellow raincoat, but most to some people don't even know who she is. she's in six's shadow, shadow six.
