Jack removed his great coat and undressed down to his boxers' right before Gwen's very eyes.

"Well if you expect me to do that then you can forget it" she said without being able to tear her eyes away from the gorgeous figure in front of her.

Jack walked out into the still part of the river. "Come on, how can you resist this?" he begged, indicating himself.

"By doing this" she said and turned to walk away.

"Fine then, I'm sure Ianto won't be as modest as you" he said to push her.

"He's busy, said he'll join us soon hang on…did you just say that I'm modest?" Gwen asked outraged.

Jack smirked knowing that he was half way there to persuading her. "It's ok, I understand you're afraid. Maybe you should just go finish the tent and while you're at it you could put dinner on." Yep, he had her.

Afraid! I'll show him afraid. It's not that she was embarrassed about Jack seeing her in her underwear, or that she was ashamed of her body. Truth was, she was scared of what was in the river, not Jack but what she could not see. Everyone's afraid of something right? Just because she happened to catch aliens meant nothing. Growing up in the real world (well, so she thought) she had never been afraid of aliens, because aliens didn't exist. She was afraid of the dark and her parents dying, and as she grew older she became concerned about being attacked but of course that had all changed once she joined the police force. But one thing never changed, since she was a child she had leant the hard way that there is always something in the water. Of course the second that Jack had used the word 'afraid' she was on a mission to prove him wrong and no childhood trauma was going to stand in her way.

Gwen tore off her jacket and threw it angrily on the ground, her eyes never leaving his as she stared him down.

Jack watched in amusement as she set out to prove herself, just like he knew she would. Some things never changed.

Gwen reached down and skilfully pulled her top over her head revealing a white lace bra. She kicked off her shoes and unbuttoned her jeans slowly as she prayed to God that she wasn't wearing her sexy knickers. She pulled off her jeans and subtly put her hands behind her back and was relieved to find that nothing was riding up her arse. Her underwear was also white with pink and blue strips. Not exactly co-ordinated but hey, it's not like she was trying to impress anyone, right?

Jack's breath caught in his throat at the sight of her. Unfortunately for him, Gwen noticed and he had immediately lost control of his own game.

"Now look who's afraid" she said smugly as she stepped into the water. "God, its freezing" she gasped.

Jack laughed.

"You could have warned me" she said.

"Backing out already?" he teased.

She glared at him. She had already proved herself and she knew that once the water got deeper that she wouldn't be able to stay in control. So, why not back out while she was ahead? She knew that Jack was just playing with her and that he really did want her in there, so if she got out…then she could tease him for a changed.

"As a matter of fact, yes" she replied and turned to walk back in.

Before she could go far, Jack raced up to her and wrapped his arms around her waist from behind. Then he lifted her up and started walking backwards.

Gwen tried her hardest to get free but his hands were fixed firmly around her waist. "Put me down!" she yelled. "You are so going to regret this!"

"Trust me honey, there is nothing you can do that would make me regret this" said Jack.

He had a point. The more she tried to hurt him, the more he seemed to enjoy it. Jack always did love a challenged. But she was determined that she was going to find his weakness and get her own back.

As the water passed Jack's stomach, he spun Gwen around in his arms so that he was cradling her. He looked into her eyes and hesitated, before dropping her into the water.

Gwen didn't lower herself to begging. She knew it would happen from the second he took hold of her. She emerged from the water gasping from the cold and lunged at Jack pushing him under the water.

"Hey Gwen" Ianto called out from the shore. "I'll help you drown him if you want."

"Thanks Ianto I would, but he would probably just enjoy it" she replied glaring at Jack who couldn't hide the smirk on his face. "What's that?" she asked Ianto.

"Air mattress" he replied.

Gwen looked puzzled. "Why?"

"You'll see" he replied. He stripped down to his boxers' and walked into the river, carrying the mattress with him.

"Do you know what he's doing?" she whispered to Jack.

Ianto jumped onto the mattress and paddled out into the current, headed straight for the rapids.

"Hey Ianto" Jack called out. "If you go further than the first three you won't be able to get back."

"What on earth are you talking about?" asked Gwen.

"He's going down the rapids" Jack replied.

"Is that safe?"

"Yeah sure" said Jack.

"I'll be back in an hour" Ianto called out and disappeared down the rapids.

Jack and Gwen heard his cheering in the distance. Jack looked at Gwen. "Want to try it?" he asked.

"No I'm fine" she said quickly.

"Oh…" said Jack. "So that's what you were afraid of" he said.

"No!" she stated weakly.

"Fine, whatever you say" he surrendered.

Gwen went to argue back when she felt something slimy brush past her leg. She let out a small scream and without thinking leaped out of the water and grabbed hold of Jack for dear life.

"What the hell was that?" she gasped.

"Calm down, it was probably just an eel" said Jack.

"I bet you're just loving this aren't you" she said, still holding onto him tightly.

"Gwen come on, you know I'd be lying if I said that I wasn't" he said jokingly.

"It's not funny!" she said.

"I'm sorry" he said. "Here, lie back."

"Why?"

"Just…trust me, ok?" he said.

"Ok" she said reluctantly.

Gwen let go of Jack and laid back on the water's surface. She felt his hands beneath her, gently holding her up. Slowly, he moved her in circles across the water. Gwen closed her eyes and listened to the sound of the water flowing around her.

Eventually Jack lifted her up and cradled her in his arms.

"What is it?" Gwen asked as she caught him staring at her.

"It's nothing" he replied. "Are you feeling better now?"

"Yeah" she said.

"So do you want me to put you down?" he asked awkwardly.

"No" she said quickly. "I mean, only if you want to."

Jack smiled. "How about we finished that tent before Ianto gets back."

"Ok."

"Here, climb on my back" he said and carried her out of the river.
