"Where are we, Doctor?" Amy's voice echoed eerily through the dusty chambers of the abandoned castle. The sun shone through the stained-glass windows, leaving glowing footprints on the floor. The grey, heavy stones of the castle seemed weary of age, as if they were sick and tired of holding up the ceiling.
Fenn stepped over an antique, dusty woven rug, eaten bare by moths. "I don't know where we are, but it's certainly not the Eye of Orion. What have you gotten us into this time, Doctor?"
The Doctor was inspecting a huge crystal chandelier that lay scattered in pieces on the ground. "I don't know. Must have overshot the temporal coordinates."
Amy rolled her eyes, "Again."
Rory stood close behind her, "So where and when are we, Doctor?"
"Earth, definitely, though when is another question. Looks almost like the Middle Ages."
"Hey Doctor, come and look at this!" Fenn's voice echoed back to them from the next chamber in the run-down castle. They stepped through the door to see her pulling out richly embroidered fabrics from a dusty, old, creaky chest. Amy and Rory laughed as the Doctor spotted a rich blue robe and tugged it on, and began twirling around the room to make it flare out. Fenn gasped with admiration as she pulled out what looked like a gold-embroidered maroon sheet. She held it up to the light, admiring the texture and handiwork of the piece- it was obviously done by a master weaver. She slung it over her arm to look closer at the intricate embroidery, when her arm disappeared.
"Um... Doctor? You might want to see this."
"What is it, Fenn?" The Doctor came dancing over in his robe, while Amy and Rory stood looking out the window at the marvellous views of the lake and mountains below.
"My arm just disappeared."
"What?" His brow furrowed as he saw that Fenn's arm had, indeed, disappeared, along with the cloth, "Can you still feel it?"
"Yes, I'm still holding the cloth."
Fenn dropped the cloth, and suddenly her arms were back in reality. She looked at the Doctor, and they both looked at the cloth, which was now lying on the floor. The Doctor just had to say it.
"It's an invisibility cloak."
"What, like off Harry Potter?"
The Doctor grinned, "Exactly like Harry Potter." He picked it up and stretched it out.
"No, Doctor, don't-" Fenn started, but it was too late- he'd already thrown it over himself and disappeared.
"-do that!" Fenn sighed with exasperation. Amy and Rory came over from the window, "What's wrong? What's he done this time?"
Fenn was about to answer, when suddenly she collapsed to the floor in a fit of giggles. Amy and Rory looked down at her in alarm, "Are you alright?"
"Hahahahahah, he's- ahaha- he's tickling me! Hahaha Doctor haha stop it ahahahaha!"
Amy and Rory just looked at her for a moment, "But there's no one there!"
"Stop it, Doctor! No, no, no hahaha, stop it!"
Amy rolled her eyes and was about to walk back to the TARDIS when she jumped a mile high and started giggling too, "Hahaha, ticklish, no, don't, ahaha, stop it!"
Rory just looked at the both of them and walked back to the TARDIS. He went to open the door, but it magically opened before he got there. He stepped inside cautiously, when the Doctor jumped out of nowhere from behind him and yelled, "Gotcha Rory!"
Rory almost collapsed from shock. Fenn, who'd been recovering in the doorway, lapsed back into hilarity at the look on Rory's face.
