Carol replies:
OTOH, "emerging out of thin air" is Harry's perception, meaning that
he had no idea where they came from. And I didn't suggest that Malfoy
yelled now. I had in mind a silent signal, with the DEs moving
silently forward. I think that the DEs, wearing black from head to
foot, would not have needed a disillusionment charm since they were
already the color they would have to appear (black) to blend into the
sahadows. A disillusionment charm doesn't maek a person invisible. It
merely acts as camouflage, which is exactly what the black cloaks
would do. And they wouldn't have been hiding where Harry expected to
find Sirius. Just my opinion.
