Ooookkkk.... this one is kinda interesting. So, Moonbli is confirmed by the end of book 10, right?

But in book 7

Moon: You're better than most dragons, actually.

Moon: Winter, I believe you are one of the best, truest, bravest dragons in Pyrrhia.

Book 6

Moon: (Thinking) It was impossible to ignore how handsome Winter was.

So, I have mixed opinions on Moonbli vs. Winterwatcher.
