That's a very good point, Sally-Anne -- to make her look young enough to qualify for the machine at first glance, but edging older so that people wouldn't jump to the conclusion it was a metamorphmagus.

I'm hoping that if we do things right, it'll be unclear enough as to what happened so that fingers might not point to the 'victim' in the first place -- we may be able to set Strangeweale up for a fall that places the blame on him.
