Here's the idea:
My inspiration comes from disneydweeb's fan fiction about Aladdin and Jasmine's daughter Sapphire, well mine is the same except mine is about Snow White's and Prince's daughter who I haven't come up with a name to, but if you have any suggestions please comment with what the name should be. I'm not so sure about the story yet, but I think that it's going to be about that the little daughter one night has a nightmare where she's running in a dark forest and the next morning she and Snow White takes a walk in the forest and after a while she feels better, but when they return to the castle they see a queen who happens to be the sister of Snow White's stepmother. This one is also very vain and when she sees the daughter she feels jealous over her beauty, so after that you know the story, but I will add some small twists to it, but you'll see those when I post the fan fiction.
I'll post it after I'm done with Alexandra and the Princesses and Alexandra and the Swan, but I might post it while I'm holding on with Alexandra and the Princesses so that you don't need to wait very long for it to come.

Ooh, I can't wait for this!

Sounds pretty good. Write it as well as dweeb and it'll be a hit.
