Jack loved big parties and really, he'd thought he would be spending the night ringing in the new year at a club dancing or something like that, but Harry was going to be at the Leaky with some friends and against his first instinct (not to go, because there would be a lot of people there and the possibility of getting caught was definitely higher) because Harry wanted him too. And also, he wanted to kiss Harry at midnight. Because that was romantic, and stuff. Mostly Jack was just worried about his brothers finding out, but maybe the amount of people would provide a bit of cover. In any sense, Jack was at the Leaky Cauldron, wearing a hooded jumper, with the hood pulled up and a hat pulled down to his eyebrows. Wading through the crowd of people, Jack spotted Harry and his group and made his way to their table.
He came up behind Harry and put his hand on the man's shoulder, grinning at the others before leaning down and kissing Harry on the lips before he could react too much. Jack grinned and laughed, "I think Ogden's might be a bit much for you, maybe you should have a butterbeer, hm?" he teased, before looking to the others and giving a half-shy wave, "Happy New Years, all."
