Riddle has done a runner
Death
With both Malfoy and Snape silenced, Harry continued on his journey to find Riddle. It was a long and treacherous journey for him and there were blast ended skrewts and what-not coming out left, right and centre. Harry thought that this must have been one of Voldemort's ways to stop Harry from getting to him.
Harry was really wound up by the fact that Voldemort was trying to do everything he could to stop Harry from getting to him. It wouldn't be so bad if Voldemort didn't know every trick in the book to stop people right in there tracks.
Then there was a voice.
A cold voice.
An icy voice.
The unmistakable voice of…
TOM MARVOLO RIDDLE.
And then…
An ear-piercing scream from a girl known as
HERMIONE GRANGER!!!
Coincidentally, the scream was right after the words Avada Kevadra.
"Hello, Harry," came the icy voice.
"Come closer you coward!!" Harry demanded.
"Fine" said the icy voice simply.
