Alice had said, when she told her about this whole idea that she had, that cause of all the budget cuts and the severe lack of money that the school had, that there wouldn't be any butterflies in the gardens. So naturally the Claw had to check and see if it was true, and sure enough there was no butterflies and a sign to tell her that none were coming.

When they finally were butterflies,
Dora gathered up the ones not eaten by her jarvey and put them in a small enchanted box that had holes on the top so they could have some air. Making her way through the gardens, she found the prettiest spot and settled down with the box and her satchel.
They said they would met just before sunset, and that he would bring the food. Dora brung herself, so now all she had to do was wait for him to show.
