Ok here where I'll put my questions and hopefully somepony will be able to explain 

1. Why does Celestia always have a solid pink mane when she a filly.

2. Why does Luna have a light blue mane when we first see her after Nightmare moon defeat, but after that, she has a wavy mane.

3. Why does everyone ship celestia and discord? They never got along much, and didn't interact much even when he was reformed. 

4. Why is chrysalis a queen, but celestia is only princess?
