Oh god this was going to end so badly, Sirius could feel it - even without Regulus' remark. Thankfully James was able to over look it, whether on purpose or not, and Sirius was just glad for the lack of bloodshed for the moment, though he did smack the back of Jamie's head when he patted his cheek. "Hands to yourself, Prongs, unless you want me getting ideas." He warned his friend with a smirk.
He took time to peek here and there as Lily and Jamie lead them to the dining room, and then took a seat at the table with James at his side. "Who doesn't like chicken?" Sirius commented with a smirk, while they passed around glasses of champagne.
"You know what would go really well with this?" Sirius said holding up his glass, contemplating it for a moment before grinning at Lily and Jamie. "A bit of news which is still being held hostage for some strange reason."
