A/N: The closing fanfic in the "Many Smiles" series. I'm so excited, so PLEASE read and review to tell me what you think! Hmm…for my next Tate fic, I'm thinking chocolate, a bunch of stories about chocolate. Is that do-able? We'll see…anyway, thanks (as always) to my beta reader Smackalicious, for being so fantastically fantastic!

It was Christmas Eve, and the whole team was just getting ready to head home.

"So, what are you doing for Christmas, Tony?" Kate asked, throwing the question casually over her shoulder as she gathered her purse and coat. They both stepped into the elevator as he replied.

"Oh, just me, myself, and I, probably gonna watch some old movies or something at my place," he said. Kate knew that Tony had some problems with his family in the past, but not being with anyone for Christmas just sounded depressing.

"So you'll be all alone?" she asked as they stepped into the parking garage.

"It's no big deal," he said, and got into his car. "Merry Christmas."

"You too," she said, watching him pull out and drive away before getting into her own car. Once she was on the road, she pulled out her cell.

"Mom," she said, "I'm not gonna make it tonight. I know it's Christmas Eve, but there's someone I've got to go see."

She made a quick stop home, changing clothes and picking up a few things, before heading for Tony's apartment. It was only a short drive, and in minutes she was outside his door. She could hear the sounds of a movie being played from inside.

"White Christmas?" she asked when he answered, ignoring his look of surprise.

"Yeah. Bing Crosby and Danny Kaye," he said as she stepped past him into the apartment. "It's been my favorite Christmas movie since I was a kid."

"Hmm," she said distractedly, looking around the room. Her gaze rested on the dilapidated Christmas tree in the corner. She stared at it for a moment, lost in thought. It was quite small, with its branches drooping and scattering pine needles everywhere. Tony had done his best to decorate it with colored lights and clear glass balls set at strategic intervals to reflect the lights. There were a few gifts underneath it, and one caught her eye. It was a small, brightly wrapped box, just big enough to fit in the palm of her hand.

"Katie?" Tony's voice broke her wandering train of thought. "Why are you here? I thought you were spending Christmas with family." She smiled, letting the "Katie" slide, and walked over to him. She handed him the gift she had been holding since she arrived, and kissed him gently on the mouth. No time for nerves now.

"No one should spend Christmas alone," she whispered in his ear. Tony said nothing, but went over to his tree and retrieved the box that she had noticed earlier.

"Open it," he said, handing it to her. With trembling fingers, she did so, untying the ribbon and slowly pulling the festive paper away from a simple black jewelry box. When she took off the lid, she gasped. Inside were an absolutely stunning diamond ring and a short note. She looked up at him, ignoring the note, because she already knew what it said. All she could see was Smile Number 50, at its brightest. It spread not only over his lips, but up through his beautiful green eyes. It was those eyes she stared into now.

"Yes," she whispered, and once again, those soft lips met her own in a passionate kiss. They kissed happily, knowing that neither would have to be alone for anything, ever again.
