Can you take a guess...?

I have questions about HP that haven't been answered, like all of us. like, for instance...
What did Dudley saw when he was attacked by the dementor?
What happens with Umbridge when she is taken by the centaurs?
Who replaces Snape as Headmaster of Hogwarts after DH?
I can take a guess about that and more, but I would like to know what do you think...

Dudley didn't see anything. He saw Harry lift up all by himself and was unsure what to think. As for Umbridge, well I hope they had her tied up in a stable or something to that effect. And fed her hay to see if she would like it, oh and gave her a bucket to drink out of. And headmaster at Hogwarts I think was McGonagal.

It is hard to tell what Dudley saw, since he's not that important character, and the only side of him we get to meet is the one where he enjoys torturing other kids..
and what would it mean to you if JK told you, for example, that his worst memory is when some kid beat him up?

To Umbridge.. probobly nothing serious - in the book we're told that both, Dumbledore and Umbridge appeard without any real injury

And i agree about McGonagal being a headmisstres of Hogwarts.. she was suppose to become that at the end of HBP

How do yo think Tom Riddle felt whenever his horcuxe got destroyed?(his soul I thought was torn everytime and extreme sense of dying and leaving existance)

he didn't feel anything.. or he felt but didn't want anyone else to know, so he hiden his thoughts from JK
i don't think his soul was torn when horkrux was destroyed, but when it was made, so from the moment the object became horkrux it lived it's own life and had nothing to do with Voldemort

True about the horcruxes...
I wonder what was Dudley's worst memory... Take a guess?
