This is the first thing I've ever let anyone else read, so I guess I'd be obliged if anyone who leaves a comment would be constructive and nice. This may or may not grow into a proper (well, I say proper) story, but mainly it's to ask you, gentle reader, if I've got the characters right enough to continue. Hope you like it.
"Well," said Rose, a diplomatic tone in her voice. "At least we're in the right place. Just a few months out, that's pretty good for you." She shivered and wrapped her arms around herself. Her thin jumper was doing little to protect her from the chilly conditions. "Bit cold though, isn't it?" she laughed.
"Oi, watch it you, or I might just take off and leave you here," he joked back before shoving his hands deeper into the pockets of his tan coat. He'd never admit it out loud, but she was right. A few months out and he'd landed them smack bang in the middle of winter. And it was freezing.
"You wouldn't dare!" Rose squealed in mock horror.
"I would too! It'd be a lot quieter without you around, I can tell you," he sniffed as he turned to survey the bleak surroundings. Big mistake. Something soft and wet impacted squarely with the back of his head. Spinning round he found his darling companion standing there, a look of near angelic innocence on her face, blonde hair shining in the low winter sun.
"Sorry," she apologised with a cheeky smile, "I couldn't help it." He shook the snow shrapnel from his messy hair and made a show of brushing himself down from the shoulders to the knees. In a flash, he scooped up a handful of the pure white snow, compacted it into a vaguely snowball shaped lump and hurled it at Rose. She squeaked and flung her hands up to shield her face but there was no need; in his haste he'd aimed wide and the missile thumped harmlessly into the snow behind her.
Right, she thought, that was it. Abandoning all caution, she crouched to pick up her reply. The move gave her intentions away and the Doctor made a clumsy dash for cover behind the solid blue bulk of the TARDIS, his movements hampered somewhat by the fact that he sank to his ankles in the snow with each footstep. Forming her snowball carefully, she set it aside and made a second before picking up one in each hand and setting off towards the Doctor's rather obvious hiding place. They were the only visible living things for miles around, although chances were there might be a few bemused squirrels or the like watching from the wood down in the valley. Pausing for a moment, she could hear his footsteps crunching in the snow on the far side of the blue box. Slowly, she crept up to the TARDIS, then charged round it only to be confronted with empty space. Before she could realise what had happened she heard him rush round from the other side of the TARDIS and suddenly she felt a freezing cold sensation running down her back. She gasped, the shock of the cold taking her breath away. The Doctor laughed and took a precautionary step back as she turned to face him, the angelic expression of before replaced by one of total shock. Her hands acted of their own accord; she lobbed both snowballs at him at the same time. One hit him on the shoulder as he spun to protect himself. The second took him on the neck, snow sliding down under his shirt collar, his breath catching as it trickled down his skin.
Stumbling backwards away from Rose, who was deftly forming new ammunition, he dodged back round the side of the TARDIS. Carefully, he brushed the snow from his collar, trying not to let any more slip down inside. A snowball whizzed past his shoulder to thud into the solid wooden side of his cover and he decided it was time to move. He sprinted full pelt away from the TARDIS, arms shielding his head as a lucky throw from Rose landed yet another snowball on target. Only then did he realise he might be outclassed in this kind of fight.
Rose knew she was winning and laughed as the Doctor tried to put some distance between them, chucking lumps of loosely compacted snow back at her. Those water-bomb fights back home when she was a kid were paying off; her aim wasn't as bad as she'd thought it was. Granted, most of her missiles were landing harmlessly in the snow, exploding on impact into little puffs of powdery white shrapnel, but she had the Doctor on the run. He pulled a weird kind of pirouette to avoid a snowball that looked funny enough as it was, coat-tails fluttering round him, before completing the comedy moment by slipping and falling, arms flailing, into the soft snow. Rose ran over as fast as she could in the snow, taking care not to fall herself, which was quite hard owing how much she was laughing at the Doctor's failed stunt. As she neared the prone form lying in the snow, it suddenly rolled over onto its side and lobbed a surprise snowball at her. She shrieked and ducked as it sailed over her head. She reached the Doctor, still lying in the snow after his unsuccessful attack, and weighed her remaining snowball in her hand.
"Truce, truce!" he shouted, hands raised in a placating gesture. "Peace! No more!" The victor struggled for a moment to maintain her threatening expression then dissolved into giggling. He didn't half look pathetic, covered in snow, lying at her feet. Rose tossed the last missile over her shoulder, dusted off her hands and then offered one to the Doctor, who grabbed it and let her pull him upright.
"Your hands are freezing," he observed, taking both of hers in his own. She didn't answer, meeting his gaze for a second before looking down at the trampled snow.
"Come on," the Doctor said, putting his arm around her and steering her towards the TARDIS door. "If we're going to look around this place properly, I'd better find you a coat. Your mum would kill me if she found out I let you catch cold." He grinned at her and held the door open for her to step back into the warmth of the TARDIS.
