Right after Potters' death; Sirius' Bike

'I met him! I musta bin the last ter see him before he killed all them people!
It was me what rescued Harry from Lily an' James's house after they was killed! Jus' got him outta the ruins, poor little thing, with a great slash across him forehead, an' his parents dead... an' Sirius Black turns up, on that flyin' motorbike he used ter ride. Never occurred ter me what he was doin' there. I didn' know he'd bin Lily an' James's Secret Keeper. Thought he'd jus' heard the news o' You-Know-Who's attack an' come ter see what he could do.
White an' shakin', he was. An' yeh know that I did? I COMFORTED THE MURDERIN' TRAITOR!' Hagrid roared.

'How was I ter know he wasn' upset abou' Lily an' James? It was You-Know-Who he cared abou'! An' then he says, "Give Harry ter me, Hagrid, I'm his godfather, I'll look after him - Ha! But I'd had me orders from Dumbledore, an' I told Black no, Dumbledore said Harry was ter go ter his aunt an' uncle's. Black argued, but in the end he gave in. Told me ter take his motor-bike ter get Harry there. "I won' need it any more," he says.'
'I shoulda known there was somethin' fishy goin' on then. he loved that motorbike, what was he givin' it ter me for? Why wouldn' he need it any more? Fact was, it was too easy ter trace. Dumbledore knew he'd bin the Potters' Secret Keeper. Black knew he was goin' ter have ter run fer it that night, knew it was a matter o' hours before the Ministry was after him.
