"Natalie?" Charlie croaked his head emerging from beneath the black winter cloak. "Is that really you?"
"Yes you ninny! What's going on?"
"Why should I know? I was walking along the mountain path trying to get...well it doesn't matter, when this monstrous dog pulled me off the path. I landed down here and he dragged me into this cave. I've heard a lot of roaring and then a large amount of snow landed outside. Hey, where are you going?"
Natalie had got up and walked out from under the shelter of the cave mouth, closely followed by the big black dog which frisked around her legs. She could make out the path just above the roof of the cave which explained why neither she nor Charlie were hurt by the fall from the mountain trail. Charlie was right, there was an awful lot more snow on the ground. Natalie was sure she hadn't been knocked out, so the snow couldn't have fallen whilst she had been lying just within the entrance of the cave. She scanned the landscape but everywhere was the white of fresh snow, which glistened in the slight moonlight, making it take on a slight tinge of blue where before it had been grey.
Natalie noticed a slightly discoloured lump a little way away. As she walked over to investigate the dog raised its hackles and growled. She took the hint. Even a few steps closer was enough to tell Natalie that this was the Graphorn, either knocked out or dead. Natalie thought about what Charlie had just told her. Lots of roaring and then lots of snow falling all at once. Natalie remembered the rumbling she'd thought was the Graphorn and realised that could well have actually have been an avalanche, dumping a lot of snow on top of the Graphorn and Charlie's cave.
Natalie inspected the mountain path afresh and realised that not only was it going to be incredibly difficult to get back up to the level of the path, the snow was so thick neither she or Charlie would ever make it back to Hogsmead.
Natalie stepped back into the cave, where she found Charlie huddled in his cloak against the side.
"Are you cold or something?" Natalie asked
"Well yeah! Duh!" Charlie rolled his eyes at her. Natalie pulled out her wand and conjured blue fire which began to crackle immediately and washed warmth over them.
"Duh!" Natalie said smiling.
It dawned on Natalie that it would be a long time before they were found or able to get back to Hogwarts. It looked like she would be spending the night alone in a cave except for a large dog and the person she considered to be the love of her life.
