This is going to be a humorous post, but here is all the proof I believe support the insane theory that inside Charlotte there is actually Dolores' horse. Please feel free to add more clues if you think I have missed some.
1. As soon as Charlotte is brought online Dolores says "You are a CREATURE of beauty and power". It's a well known fact that horses are indeed creatures of beauty and power.
2. Her horse was always beside her so it makes sense that it knows who Charlotte Hale is and is the only one Dolores trusts.
3. Charlotte looks at her hands a bit surprised because of course is used to having hooves.
4. "How well do you remember your science?", the horse avoids this question because obviously it has never gone to school and studied science.
5. It instantly kisses Charlotte boyfriend because it is eager to try human sex.
6. Does not tuck Nathan right because it is not used to sleeping on a bed.
7. Hursts herself because it's an animal inside a human body.
8. "In case you have to kill me", when horses got badly hurt in western times they would get shot by their owners. Dolores takes out a gun in the hotel room for this reason.
9. The whole hotel scene proves this theory, rewatch it imagining Charlotte is a horse hahaha especially "You belong to me".
10. The big spoon could be looked at as the rider while the small spoon is the horse, pretty good metaphore right here.
11. "You are not the only predator here", let's consider for the sake of this theory that horses are predators.
12. Lastly the biggest piece of proof is that at the end of the episode interview Lisa Joy says that Charlotte has "animal instinct"!
I think this pretty much completely proves the theory, feel free to quote me in the following weeks when Charlotte neighs by mistake.
