"Welcome to Blaned Eira 7. One of the twelve year-round winter planets," the Doctor shows Rose the white planet outside the doors of the TARDIS. Her hazel eyes widen in wonder as she pulls the golden parka around herself more tightly against the cold breeze.
"S'beautiful," she remarks in awe at the frozen wonderland.
"Colonized by humans fourteen hundred years ago, this planet was a pleasure planet for twelve hundred years. Over those twelve hundred years, so many employees moved here that it became a colony," the Doctor informs. Rose steps out of the TARDIS to see a sleigh being pulled by a form of horse, only twice as large and with a horn on it's head.
"Is that…?"
"Yep," the Doctor pops his 'p', "A genuine unicorn. Although, it doesn't possess magical properties."
"Wow."
"Yeah," the Doctor remembers something, "Hang on." He goes back into the TARDIS for a minute before emerging with a sleek, red sled.
"No way," Rose grins, "I've never been sledding. London doesn't get 'nough snow."
"Well then, Rose Tyler," the Doctor revels in the way the syllables trip off his tongue, "Let's go for a sleigh ride."
Rose pulls a thin string of sleigh bells from her pocket and shakes them, smiling as they jingle, "The TARDIS must have left them in there." She drapes them on the sled and the both grab the handle, pulling the sled up a white hill, listening to the cheerful jangle of sleigh bells.
"Just hear those sleigh bells jingling, ring ting tingling to," Rose sings.
The Doctor grins, "Come on it's lovely weather for a sleigh ride together with you."
"The snow if fallin' and friends are callin' 'you-who'."
"Come on it's lovely weather for a sleigh ride together with you."
Together they chorus, "Giddy-up, giddy-up, giddy-up let's go. Let's look at the show."
Rose sings soprano, "We're ridin' in a wonderland of snow."
"Giddy-up, giddy-up, giddy-up it's grand, just holdin' your hand."
The Doctor's baritone adds, "We're gliding along with a song of a wintery fairy land."
They both know the next lyrics and hesitate singing them as they reach the top of the hill, turning the sleigh around and sitting on it. Rose in the Doctor's lap, his arms around her middle as she grips the handles in her mittened hands.
Bravely, Rose continues to sing, "Our cheeks are rosie and comfy cozy we're snuggled up…"
She waits for the echo and the Doctor obliges softly, "Together."
"Like two birds of a feather will be," Rose continues.
"Let's take the road before us and sing a chorus or two," the Doctor sings a bit stronger, "Come on it's lovely weather for a sleigh ride together with you."
He then pushes off so they zoom down the hill, Rose clutching the Doctor's gloved hands that are wound around her waist.
They both whoop in happiness and exhilaration as the blades of the sled cut through the icy snow of the ground. The frozen water droplets flinging up in flurries behind them in their wake. With a bump over a hidden rock, the sled overturns, tossing the riders into a snow drift, the Doctor's hands being yanked from Rose's.
With a pop, the Doctor's head appears from the hill of snow and shakes the flakes from his frozen hair.
"Rose?" the Doctor clambers out of the snow bank to see Rose's pink mitten poking out of the snow, "Rose?"
As he approaches the mitten, the wind shifts and the mitten topples off of the snow bank, empty.
Fwpuff! Something hits him in the back and he turns around to see Rose briefly before another snowball hits him in the face. He wipes the melting snow from his eyes to see Rose laughing with several more snowballs in her arms.
"Oh, you've asked for it now," the Doctor grins as he scoops up a handful of snow, patting it into a ball, "I've mastered the ancient art of snowball fighting. Taught by the monks of Semakin Bertambah."
"Well I was tutored by the street urchins of the Powell Estates, where we fought valiantly with ice mush and nearly gave ourselves frostbite every winter." Rose boasts, tossing another clump of snow at the Doctor and landing it atop his hair.
"Oi! Watch the hair! That does it, this is war!" The Doctor begins throwing as many snowballs as he can, shaping them quickly. But he is no match for Rose who pelts him continuously. There is no reprieve. No break during which she forms her snowballs. And even during all of this she builds herself a wall of snow to block the Doctor's own firepower.
Suddenly, it falls silent. Cautious, the Doctor pokes his head out of a hole that he dug himself with his feet while he shaped snowballs. The enemy wall is silent as the grave, no snowballs being launched over and the faint sound of crunching snow coming from his own trainers across the frozen ground.
"Rose Tyler you better not have died," the Doctor teases playfully, hiding his irrational fear as he inches closer, "What would I tell your mother?"
"That you were beat by a girl!" she cries as she launches an enormous snowball at the Doctor's face before tackling him to the ground. She laughs triumphantly as he splutters and attempts to get free. Hooking her feet over his thighs and her knees on his shoulders, she straddles his torso, pinning him to the ground.
"It appears that you have beaten me, Rose," the Doctor tells her woefully.
"Yes, I have," Rose answers smugly, "Wait, what do you mean 'appears'?"
"Because I know Venusian Aikido!" The Doctor flips over and pins Rose to the snow, laughing as the tables turned, "Now I have beaten you."
"You smug bastard," Rose grins, "Although I wouldn't say I've lost."
"You wouldn't?"
"Not at all," she reaches up and presses her lips to his, and he stays on top for a while.
