'Nice commentary last match!' said Ron to Luna, as she took back the green onion, the toadstool and the cat litter. Luna smiled vaguely.
'You're making fun of me, aren't you?' she said. 'Everyone says I was dreadful.'
'No, I'm serious!' said Ron earnestly. 'I can't remember enjoying commentary more! What is this, by the way?' he added, holding the onionlike object up to eye-level.
'Oh, it's a Gurdyroot,' she said, stuffing the cat litter and the toadstool back into her bag. 'You can keep it if you like, I've got a few of them. They're really excellent for warding off Gulping Plimpies.'
And she walked away, leaving Ron chortling, still clutching the Gurdyroot.
'You know, she's grown on me, Luna,' he said, as they set off again for the Great Hall. 'I know she's insane, but it's in a good way.'
