Offering her a falsely sincere smile, he removed a hand from a pocket and walked over toward Severus, slinging an arm over his shoulder, satisfied at the glare that he received.
"Why yes, it's been most interesting, to say the least. Thank you for thinking to ask, Narcissa. And where shall you two great friends be off to next?" The smile twisted into a smirk when Lucius turned to look at Severus, giving him a friendly squeeze with his arm while dragging him from his seemingly cemented spot.
"Might I suggest Madam Puddifoot's? Most of the mindless couples enjoy going there for a quick snog or two. I hear the atmosphere is conducive to such activities." He could practically feel the inky eyes of Severus boring into his skull when he tossed a semi-interested look at Narcissa, coming off as nonchalant as he could.
