Remus J. Lupin

'Give five signs that identify the werewolf. Excellent question.'
'D'you think you managed to get all the signs?' said James in tones of mock concern.
'Think I did,' said Lupin seriously, as they joined the crowd thronging around the front doors eager to get out into the sunlit grounds. 'One: he's sitting on my chair. Two: he's wearing my clothes. Three: his name's Remus Lupin.'
