Rose was starting to hate their "exploring". It was miserably hot on the island and her hair was starting to frizz from the humidity. She realised that she would take drab London weather over this any day.

Finally, when the sun was starting to sink low in the sky and Rose thought her legs could take no more, the Doctor stopped on a rocky surface. He waved his sonic screwdriver around in the air. "I'm picking up a tunnel... like a cave entrance maybe," he muttered.

Rose stepped forward a few steps and then screamed as her feet went out from under her. She'd fallen down a hole, and was now tumbling down into the unknown.

At last she hit the bottom of the hole. "Rose! Rose are you okay?" she heard the Doctor yelling down the hole. She groaned and sat up, rubbing her shoulder where it had slammed into the hard stone floor.

"I found your cave entrance, Doctor!" she yelled back up to him. Rose shakily got to her feet and looked around to try and see where she was, but it was too dark to make out much detail. She attempted to climb back up the way she came down, but found it was too steep. "I can't climb back up!" she called to the Doctor. She heard him calling her name again.

"Rose! Stay there, alright? I'm coming down to get you!" A moment later the Doctor came sliding down the tunnel as well. He landed with a thud on the ground and lay there for a while before getting to his feet.

"That was... fun," he groaned. The Doctor stood and brushed the dirt off of his suit. He clapped his hands together and smiled. "Now then. Let's get to business."

The Doctor lead the way using his sonic screwdriver as a torch to navigate the dark tunnel. They walked for only a few minutes, until they came across an entrance with light shining through.

They entered the room to find that it was a sort of cavern with a tall domed ceiling, a hole at the very top, and a small blue pool in the centre of the room. There seemed to be an underwater tunnel leading out to sea in the pool. The source of the light came from the full moon, which was nearing the centre of the hole at the top.

Rose stared open-mouthed at the odd room that they were standing in. The Doctor however immediately started scanning the room with his sonic. He occasionally muttered incomprehensible things to himself as he scanned.

Rose approached the edge of the pool and dipped her finger in it. The cool water felt strange, but in a good way. Like it was magic. It seemed to be calling to her. "Rose..." she heard a whispered name in her head. The water was pulling her. "I need to be in the water," she thought to herself.

About that time, the Doctor spun around quickly. "Rose! Whatever you do, don't touch the water! I'm not sure what this place is but there's something not right about it."

Too late. There was a splash and Rose was in the middle of the pool, captivated by the moon that was now directly overhead. The water around her started to bubble and steam, swirling like a storm. But she hardly noticed.

The Doctor was begging her to get out of the water. He didn't trust this place. It felt all wrong, like something bad would happen if they stayed too much longer.

Once the moon passed out of sight, the water calmed and Rose seemed to get her sense back. Her eyes cleared and she realised she was in the middle of the pool. "Oh my gosh, I'm sorry, Doctor. I don't know what I was thinking."

The Doctor held out a hand to help her out of the water. "It's alright. Just get out of there, okay? I don't like this place." He helped her get out of the pool. Rose was soaked to the bone, and she was shivering. The Doctor took off his long coat and handed it to Rose, whom accepted it gratefully. She wrapped it around herself and they continued to search for an exit.

Eventually, they came across another tunnel that led them to an accessible exit. Once they were above ground again, they explored the island again until they finally found the beach. Rose pointed out some lights out on the water, but it was much to far for the boat to see them.

"Not to worry," the Doctor told her assuringly. "I've got this covered." With that he reached into his suit pocket and pulled out a gun.

Rose gave him a questioning look. "Number one, how did that fit in your pocket, and number two, I thought you hated guns?"

The Doctor gave her a cocky grin. "Number one, Time Lord technology. Bigger on the inside. Number two," he raised the gun into the air and pulled the trigger. A bright light shot into the air and exploded into bright colours.

Rose grinned. "Ah, nice. A flare gun." Then raised her eyebrows. "Why do you carry a flare gun in your pocket?"

"Doesn't everyone?" he asked.

Rose wasn't really sure if he was being serious or not, so she decided to let it be.

The boat obviously noticed the flare, for they heard a screeching megaphone and then a booming voice say, "This is the coast guard! We have seen your distress signal and are on our way!" The Doctor and Rose both sighed in relief.

As they waited for the rescue boat to arrive, the Doctor looked at Rose and said, "Well I guess we're stuck here for tonight. We should probably get a hotel room or something and come see if the TARDIS is back tomorrow. That alright with you?"

She smiled. "Yeah, it's fine. We're alive and we've still got each other. I think we'll be fine."

The Doctor took her hand and they waited together.
