Severus smiled, happy about Remus' acceptance af their plans. Maybe it meant more than Severus had realised to begin with, that his lover was willing to recognise and confirm their relationship in public. For a moment, Severus forgot they weren't alone. 'You really do want me,' he said so quietly Potter probably couldn't hear. 'Oh, Remus...'
Putting his hand over Remus' once more, somehow letting out what he felt byt the way he was clinging to the man, Severus managed to turn to Potter. He was even able to assess the boy relatively positive, with the discovery of Remus' strong feelings (not that Severus had really been in doubt).
'Maybe in a week or so?' He regarded Potter calculatingly. 'You are certain you want to do this? It is not going to be pleasant.'
