Seems Mia Fey was called by a channeling through Pearl Fey, who is 9 years old in Trials and Tribulations and which makes her "liftable", if I should say. Since you get radical physical changes through channeling, guess the picture is a "proof". :P
I really don't think the tag you gonna get raped is relevant. Looks more like Godot was carrying Pearl who then channeled Mia and Mia was suddenly too heavy for him.
