Disney theme park head canon
This is my Disney theme park headcanon.
You know how there is a raven perched at various points in the Haunted Mansion? If you never noticed him there are several videos of the ride on Youtube. Well, when Walt Disney was still alive he toyed with the idea of having various villains make appearances in the Haunted Mansion.
I know Maleficent and Diaval aren't really villains in the 2014 movie but I like to imagine that the raven in the Haunted Mansion ride is Diaval. Why he's there, I don't know. But the idea amuses me.
