'I wish you'd stop sniping at him,' said Remus quietly, as Snape left Grimmauld Place.
Sirius grinned. 'You're not a prefect any more, you know.'
'I know, but there's no need to upset him. We all have to work together here.'
'Do you have any idea what's this is like for me?' Sirius snapped. 'To be stuck here, relying on people like him?'
Remus paused. But you could run and take your chances. I need to be near Severus for my potion. I need him. Then he sighed. 'No Sirius. I'm sure it's very difficult for you.'
'Damn right.'
