A whooshing, whirring noise permeated the otherwise silent room. Turning to locate the source of the noise, Gaius found himself staring at a huge, blue, box-like structure. Blinking to clear his vision, questioning what he could see with his aging eyes, comprehension finally reached him.

"Merlin!" he bellowed, certain that his charge was behind this new apparition. "What have you been meddling with this time!"

Stumbling into the room, rubbing the sleep out of his eyes, Merlin questioned a visibly angry Gaius.

"What-" but soon broke off upon seeing the blue box. "That wasn't me." he quickly exclaimed, glancing at Gaius with as earnest a look as he could muster. "I swear," he laughed, upon seeing the disbelieving face of his friend.

"Then where on this earth did it come from?" Gaius whispered, walking hesitantly towards the object of their attention. Reaching out to touch it, he quickly retreated upon hearing a loud crash that seemed to come from inside the box. The men looked at each other and turned towards it again as it opened and out stepped… a man.

"Then he said-"

"Always take bananas to a party!" the Doctor interrupted Jack, delivering the punch line that soon had them all in stitches.

"He really said that?" Rose questioned after recovering slightly from her uncontrollable laughter. At Jack's nod she continued, "But that's so-"

"Doctor!" Jack interjected, causing the pair to loose themselves once again. They leaned against each other as their giggles continued, losing balance at the sudden jolt that catapulted them into the Tardis console.

"Watch out!" yelled the Doctor, the top of his dishevelled head of hair appearing from underneath the console.

"Thanks for the warning." Rose muttered, regaining her footing, only to fall flat on her bum as the Tardis jarred once more, this time accompanied by a loud crash.

"We're here." Stated the Doctor with a roguish grin as he stood up and brushed off his trousers.

"Where?" was her reply, as Jack gave her a welcomed hand up from the floor.

"Who knows," he responded with a playful twinkle in his eye. "Want to find out?" he enticed with an outstretched arm and wiggle of his fingers.

"Allons-y!"

With those parting words, and a wink, Jack stepped out of the Tardis and into whatever world waited on the other side.

The man looked up from straitening his jacket and froze upon seeing them. He seemed surprised, but quickly recovered, and after looking Merlin up and down he stepped forward a few paces, a smile gracing his features.

"Hello. I'm Captain Jack Harkness, and who are you?" the man, apparently named Jack, spoke confidently, offering a hand in greeting.

"There's a time and a place." Another man seemed to chastise as he too emerged from the mysterious box.

"Yeah, about that Doctor; where exactly are we?" A women now entered the mix, and upon receiving a non-too pleasant look from the second man hastened to speak again: "Not that I mind of course." She looked towards Jack for assistance, but upon seeing his gaze otherwise occupied, she finally noticed the original occupants of the room. "Hi," she said in greeting, raising her hand in a poor imitation of a wave.

She received no response, for Merlin and Gaius were too busy staring in disbelief at the woman's attire. She looked down at her clothing and then at her surroundings, suddenly seeming to realise the significance of what she was wearing. "Doctor." she spoke through gritted teeth. Upon catching the second man's attention she gestured at her oddly clothed body.

"Ahh." He sounded with dawning recognition. "Not exactly dressed in medieval fashion are we." He stated, looking at the Jack's clothing as well as his own.

"No." The first man denied. "It's not the clothing. They're probably just wondering what the three of us were doing in a small, wooden box…" Jack trailed off, casting a suggestive look and wiggling his eyebrows at the woman, who merely smiled fondly in response.

Gaius and Merlin followed the conversation with rapt fascination and complete incomprehension. They looked at each other, and signalled their mutual confusion with a lifting of their shoulders and a widening of their eyes. Realising that the group hadn't spoken for a while, the men looked back at the threesome, who were showing a certain amount of puzzlement themselves.

Deciding that someone needed to do something, say something, Merlin stepped forward and declared: "My name's Merlin and this," he gestured about himself, "is Camelot. How you came to be in here though, that I'm afraid you're going to have to explain for yourselves."

Upon hearing their location the woman's mouth had opened in surprise and wonder.

"No way." she whispered.

The second man looked less surprised but just as happy, exclaiming with apparent vigour, "Oh yes!"
