December 25, 1890 — Off the Coast of Aberdeen
This plan was not without risks. He'd made a lot of assumptions in planning it: that because the Fisks were Jewish, they wouldn't have any plans that lasted into the evening on Christmas Day; that there was somewhere on the Fisk property Zelda could portkey from without being observed; that the Floo would be unattended later that night when she needed to return. Of all the risks, however, getting caught wasn't the one he was most concerned about. He was far more worried that he wouldn't have left Zelda a clear enough hint to figure out what the marble in the center of her "necklace" really was, and that midnight would come and go without any trace of her. Maybe she was sitting at home right now wondering why he'd been so excited to gift her a lame piece of clunky jewelry, and all his planning for tonight would be for naught.
There was nothing he could do now, though, except to wait. He busied himself making everything perfect in the meantime. The small sailboat he'd rented for the occasion was at anchor and bobbing lazily in the waves. There was a pile of warm blankets to protect them from the cold, and a thermos of cocoa nestled nearby. The lights of the nearest town shimmered across the water and he could faintly hear bells tolling in the distance. It was midnight. Any second now.
He needn't have worried. The portkey arrived just on time, with Zelda in tow. He was smiling before she'd even fully arrived and moved to kiss her immediately, relishing the fact that for once they could do this with nobody watching or caring.
"Hi. Hope you're not the sort to lose your lunch after a portkey," he joked as he wrapped his arms around her waist loosely. With a nod over his shoulder at their surroundings, he asked, "How'd I do? Do you like it?"
