The Doctor on My Shoulder, Part Two by Daniel Roth.
"Well," the Doctor said, reaching up to Cilia, "it must be your lucky day because that's me. Well, sort of anyway."
Cilia hesitated. She didn't know whether to trust him.
"I know exactly how you feel," Ana said suddenly. "Me and my dad moved here only six months back and there isn't a day that I don't miss home. The Doctor's right, though. Your people, they aren't at war anymore. You're safe."
Cilia recognized the same pain she felt in Ana. She hovered above the tree and slowly landed, pressing series of buttons on a device of her own and slowly growing to the size of an ordinary, human girl.
Mason pulled out the familiar box from the front of the house that contained one of Cilia's robot sentinels.
"Will this do, Doctor?" Mason asked.
"Yeah, that's perfect," the Doctor said. "No use in letting a good plan go to waste, eh? Now, Cilia, you just need to instruct your robots to take you back to Ulian Alpha. Do you think you can manage?"
Cilia nodded, tearing up a little bit. Seeing this, Ana reached out and hugged her.
Mason unwrapped the box, revealing the robot inside. Seeing the princess it immediately powered up its transmat beam and fired. A moment later the robot, too, disappeared.
The Doctor, Mason and Ana quickly left the neighbour's house before anyone got home and demanded an explanation. The trio marched back to the TARDIS. This time, the Doctor turned round, facing Mason and Ana before opening the door. "Well," he said. "I can honestly say I've never been in that big a trouble before. Then again, I've never been that small before, either."
"You're welcome, Doctor," Mason said, stretching out his hand.
"Thank you, Mason," the Doctor replied, shaking Mason's hand and smiling.
"What did you mean before, Doctor?" Ana asked. "You said you were sort of Father Christmas but there's no such thing."
"Who ever told you that, Ana Comparetto," the Doctor said, smiling, "is a great, big liar. In fact, here: Christmas present a bit early." The Doctor pulled a box out from his coat pocket. It was blue with a small cup on the front and white wording that read "Swiss Miss Hot Chocolate".
"That is the most miraculous thing I've seen all day!" Ana shouted. "You really are amazing. I'm going to go make some. Mason, you want?"
"Yeah, I'll meet you in a minute," Mason said.
Ana ran off with her prize held tight in her hands.
"What'll you do now, Doctor?" Mason asked.
"Dunno. There's something I've been avoiding. Something..." the Doctor's voice trailed off. "Do you know like we were talking about before with The Snowman?"
Mason nodded.
"Well, after all the flying around, having fun, and doing the impossible I've realized something: I'm the Snowman and..." the Doctor suddenly looked very grim, "time's up."
Mason sensed a profound sadness coming off in waves from the Doctor. He couldn't even think of what to say except, "Merry Christmas, Doctor."
"Merry Christmas, Mason," the Doctor replied, smiling weakly. With that he closed the door to the TARDIS leaving Mason behind. He stood in wonder as he heard a sound that he could only imagine must have been what the whole of creation coming into being must've sounded like. Then, just like that, the Doctor and his wonderful machine were gone and Mason stood, alone, in the melting snow.
