I am going to have Mal do something stupid and bad.Here are your opinions.
A: Mal gives Maddy a cupcake that puts her to sleep but sends her off to Underline aka Wonderland.
Or
B: Maleficent cast a spell on Maddy to put her in a coma, and she can only wake up to a special potion.
Ether way the crew will be going to Wonderland.
