"Kreacher is going to hold a grudge until one of us is dead." Sirius said shaking his head and grinning, though it would probably be until Kreacher himself died - because Sirius had died and the elf was still not fond of him, not that Sirius ever expected him to be. He did wonder though if Kreacher had told James, and decided to tell Dolan for good measure.
Sirius took the glass his brother offered him and chuckled. "What you went to all this trouble to set up things and now you're just going to sit there and watch while we do all the work?" He asked him arching an eyebrow at Regulus. "I have a feeling there is more than one Gryffindor who wouldn't mind a little extra help going overboard."
Sirius laughed then. "Oh yes she really would have, it's bad enough there isn't even any green here, but the music and cider." He tutted. "Mother would have a fit if she knew."
