"Me? You think I'd do something as dastardly as cheat? What do you take me for." he managed to protest with the most innocent look her could muster up. He relished the warmth that seeped into his shoulder even as he used his height advantage to glance down, smirking as he did. It wasn't cheating if you used the gifts Merlin gave you, was it? It was the Slytherin way, after all. A zebra couldn't change its spots, stripes. There was a certain level of nostalgic sadness he'd been battling all evening, though, as he spent time with all the people who'd soon be gone for good. The castle would feel bereft without them, actually, and it annoyed him that he'd somehow become sentimental.
Still, he was still very much a boy and wondered how he could get Wini to bend so he could appreciate the full effect of those bloody lounge pants. They looked soft and thin and it was just very distracting. He resorted to the aforementioned cheating in an effort to keep his eyes focused instead of ogling like a creep, not that he'd ever admit to any of it. He barely registered the crackle of cards before shoving them down himself, grinning, as his blue eyes sparkled. "I'm an excellent role model." he protested, laughing, as he recounted his admirable traits even as her wand poked his side. He yelped a little but didn't let such a thing deter him. "My grades are immaculate, I'm excellent on a broom, and a perfectly responsible prefect." he said, ticking the items in his hand as he leaned forward earnestly, ignoring the little zing in his ribs, in favor of making a point.
He also turned the other cheek during rounds sometimes (some people deserved to be cut a semblance of slack) and he had zero tolerance for the unwashed masses. He was probably way too violent during games, and, he was always in a crap mood when he was hungry. Impatient and overachieving, he was well-ware of his faults. He figured his charm sort of made those things blur along the edges, though, mostly. He knew he could be a jerk, after all, but Wini wasn't necessarily asking him to bear his heart out here. (She'd be disappointed by his response, anyway, he figured. He was usually brutally honest in the worst ways though it wasn't his words but the delivery of them that would be lacking). "Besides you like me." he accused, eyes glinting, as he shot a non-verbal tickling charm at her, making sure to pull back a lot of power so as not to send her in too much of an obvious fit.
A gentle caress as opposed to a full on attack.
