So, because writing the entire episode would be time consuming, and unnecessary, I'm skipping parts that I feel wont be needed in the story. I'll make sure to summarise every time I do so, so you wont all be left bewildered.
After examining the painting, Amy, Doctor and River rode out to Stone Henge, the Doctor having decided that the most logical place to begin looking for the Pandorica would be the famous landmark. They arrived at the stones at dusk, the sky a dull grey like the stones themselves. Soon enough the Doctor jumped to the conclusion that something was beneath the site, and they set to work on getting below.
"We need to get down there." The Doctor said, with his ear pressed to the rock he had previously been standing on. He glanced up at River and Amy.
"There's a down there?" Amy asked incredulously, but with excitement. "The Pandorica is down there?"
"Might be." The Doctor said, leaping up, "Why not?" he shrugged.
"It could work..." Mused River. "But we'd need something to get down there: the screwdriver?" She suggested.
The Doctor scanned again to make sure, but quickly shook his head. "No, it's locked by something specific, and we don't have the key."
"What's the key?" Amy asked, glancing round and walking towards the Doctor.
"Don't know," He told her as he thought. "We don't know who put it there, so we don't even know what we're looking for!"
"Great," Said Amy. "Now what?"
River was looking at the ground with a smirk, scuffing her boot at the dirt. Amy noticed and watched warily, while the Doctor looked obliviously up at the sky. "How about this?" River called, drawing his attention. He walked over and knelt down, carefully brushing the dirt from it and easing it out of the moist English soil.
"That'll do nicely." He said, shooting back up and examining it, holding it up in the dull light.
"What is it?" Amy asked, walking over.
"A key, of sorts," River told her. "It will open almost any door you come across. Very illegal, of course." She winked at Amy.
"So we can get in?" Amy asked. "What are we waiting for?"
"It's damaged," The Doctor told her. "I just need to fix it." He walked back to the stone and sat on it, pulling out his screwdriver.
Amy stood awkwardly, unsure of what to do. She didn't know how to act around River, now that she and the Doctor were a couple. Should she act like she wanted, should she sit with the Doctor as he worked, be his girlfriend? Or should she pretend like nothing was happening? River was the Doctor's future, and while in the past it hadn't bothered her, now it did; it really did. Amy had guessed last time that they had met that River was the Doctors wife in the future, and River had never confirmed it, but she never denied it either.
She felt a twinge of jealousy in her belly. Amy knew that they couldn't last forever, that their relationship was doomed one way or another... but seeing the future, seeing her possible replacement; that stung.
The Doctor looked up, feeling the spark of jealousy, the twinge of sadness that was coming from Amy. He needed to be more careful, needed to keep his walls up until he got round to explaining this all to her. Amy was picking up his feelings again, his worries about River, and expanding them, amplifying them with her own concerns. His carelessness was hurting her.
"Amy?" He called as he put up his walls. "Come here, I need you to hold this."
"Okay." She said, sitting down next to him and holding the equipment. It was a completely unnecessary job, but the Doctor wanted her to be doing something, just to keep her mind distracted. Plus, the added benefit of the close proximity to her was an attraction in itself. He continued to sonic they key, healing the deteriorated circuits within as River scanned the site.
"There's something I don't understand," Amy said, and the Doctor glanced up at her. "Why was the key just lying on the ground? They locked whatever's down there up for a reason, why would they just leave a key lying around?"
The Doctor looked up to River, who was listening.
"I don't know yet." Said the Doctor.
"Maybe someone wants us down there?" River suggested. "Are we walking into a trap?"
"But they just left it in the ground, anyone could've found it." Amy said.
"But not everyone can use it." Explained the Doctor. "It's not just any old key that you'd stick under a plant pot to remember where you put it. It needed to be fixed first."
"So it's a trap?" Asked Amy.
"Probably." The Doctor concluded.
"You're right, there's definitely something under there." River informed them. "I'm picking up readings that definitely don't belong in this time, or on Earth."
"Like what?" The Doctor asked, focusing on the key.
"I'm not sure. This whole area is filled with leftover residue, to start with, and there's something big down there." She glanced up, looking at the two of them with a knowing smile. "And, of course, there's the two of you."
Amy and the Doctor looked up in surprise as River smirked, and looked at each other guiltily, expressions eerily similar.
"I don't know what you mean." The Doctor said carefully.
"Oh, you can stop pretending," She told them. "I know all about it, I just didn't know it started this early for the two of you."
"So we keep going?" Amy asked, intrigued. The Doctor clamped down on his emotions again; Amy kept picking up on things that were trickling out.
River laughed. "Spoilers."
"But we do, though," Amy said happily. "If she knows-"
"Amy..." The Doctor interrupted, and she rolled her eyes. The Doctor was happy too, of course he was, but he couldn't bring himself to raise his hopes like that. River was a stark reminder that he didn't have Amy for ever; he didn't want to think about the future just yet.
The device chirruped and lit up - bright against the now dark sky - in Amy's hands, surprising them all. It was ready.
"Right!" The Doctor cried, leaping up and snatching it from her. "It's time we went downstairs."
I like to think this was a deleted scene, as there's a gap of atleast half an hour in the episode: Where did the unlocky thing come from, and why did they wait till it was dark?
Writing a chapter every day: Going well.
Reading books in time for lectures: Not so well.
[This is a reupload, if you're wondering, I forgot to hit save and put up the fully finished version. There's not much more to it, just a bit more dialogue]
