O.K then i have found something out that shocked me last night.
Firslty we all know Sirius Black escaped Azkaban because he was innocent and the dementors did not affect him.
We in COS when Hagrid was taken to Azkaban he said it was the worst plce he had been. But if hagrid
was innocent then the Dementors would not have affeted him.
Page 163, POA, Firebolt (chapter):
Right at the bottom in the book i read this:
QUOTE
He fell silent, gulping his tea. Harry, Ron and Hermione watched him breathlessly. They had never heard him talk about his breif spell in Azkaban before. After a brief pause, Hermione said timidly, 'Is it awful in there, Hagrid?'
'Yeh've no idea,' said Hagrid quietly. 'Never bin anywhere like it. Thought i was goin mad. Kep' goin' over horrible stuff in me mind ... the day i got expelled from Hogwarts ... day me Dad died ... day i had ter let Norbert go ...'
His eyes filled with tears. Norbert was the baby dragon Hagrid had once won in a game of cards.
'Yeh can' really remember who yeh are after a while. An' yeh can' see the point o' livin' at all. I used ter hope I'd jus' die in me sleep ... when they let me out, it was like bein' born again, ev'ry thin' came floddin' back, it was the best feelin' in the world . Mind, the dementors weren't keen on lettin' me go.'
Let me stop for a bit,if Hagrid was innocent the dementors would not have affected him.
Now read this bit.
QUOTE
'But you were inocent!' said Hermione.
Hagrid snorted.
'Think that matters to them? They don' care. Long as they've got a couple o' hundred humans stuck there with em', so they can leech all the happiness out of em', they don't give a darn who's guilty an' who's not.'
So... How do we know Hagrid was not in Knockturn Alley getting Riddles diary? We still don't really know what he was doing in there?
