A/N: This is told from the Doctor's point of view and from Devon's (The OC) point of view, but it's all in third person. Hope you enjoy.
DoctorPOV
"Ah! Cardiff!" The Doctor exclaimed, much to Amy's surprise.
"Cardiff? Like, Wales? Why are we in Cardiff?" she asked. The Doctor had promised her extraordinary places, and now they were in Cardiff.
"Rift in space and time bleeds energy that I use to power the TARDIS." He explained quickly, not wanting to waste time. "Although, I thought I could visit an old friend of mine." He said absently as he strode around the console to where Amy was standing. He took her hand and dragged her out of the TARDIS onto the streets of Cardiff. They walked for a while until they came to a giant pile of rubble marked off by police caution tape.
"Oh no, this is bad." The Doctor said, kicking some rocks across the pavement. Amy stared at him, confused.
"What's bad?" she asked. The Doctor took out his screwdriver and scanned it over the rubble.
"And it's been a while, too." He said more to himself than to Amy. He just stared at the rocks until he felt a tap on his shoulder. "Amy, I-" he started, but stopped after seeing who was actually behind him. "Jack!" he shouted, throwing his arms around the other man.
"Um… Doctor?" Captain Jack Harkness asked of the man who was hugging him. The Doctor backed away.
"Oh yeah! I regenerated, again." The Doctor said. Suddenly Jack caught sight of Amy.
"Hi, Captain Jack Harkness." He said, offering a hand. "And who are you?" Amy smiled and took his hand.
"Amy Pond." She said. Jack smiled and the Doctor uttered his customary "stop it". Jack and The Doctor began a conversation about what had happened to the Hub and it went on for what seemed like forever to Amy because she walked over to The Doctor, grabbed his hand, and pulled him around to face her.
"Doctor, can we get out of here already?" she asked quietly. "He's cute, but I'm bored." The Doctor gave a short laugh then turned to Jack.
"Want to come with us, Captain?" The Doctor asked. Jack's face lit up, then darkened.
"I don't think so, Doctor, but how about you and Amy spend tonight in Cardiff with me?" he asked. The Doctor looked at Amy, and Amy nodded.
"Sounds good." The Doctor said. Jack's smile widened.
"Aright! I'll take you guys out, buy you drinks. Oh, but wait, are you sure you can pass for 18, Doctor?" Jack asked with a laugh. The Doctor waved away the comment and led them back to the TARDIS so they could get ready to go out that night.
DevonPOV
"Hey, Devon, wake up!" Katherine whispered noisily as she poked her best friend in the ribs. Devon jumped in her seat, or at least as far the seatbelt would allow.
"Dude, I just had the craziest dream." Devon started, but Katherine interrupted her.
"We're about to land in Wales!" she shouted excitedly. Devon shushed her before they could attract too much attention. They squeed quietly, so excited to finally be in the UK after all the years of dreaming about it.
After getting off the plane and out of the airport, Devon decided it was time to bring up her dream again.
"So, I had the weirdest dream on the plane." She said, waiting to see if she had Katherine's attention.
"What was it about?" Katherine asked as they hailed a cab to get a ride to their hotel. They got inside the cab and Devon began to talk.
"We went to this club, and there was this guy, and he had a bow tie which already starts the weirdness." Devon said. Katherine laughed then gestured for her to continue. "So, the guy saw me and smiled so I went over to him and we just started making out."
"That definitely sounds like a dream you would have." Katherine laughed. Devon resisted the urge to hit her as they arrived at the nice hotel that their combined paychecks for the past two years was paying for. As they were unpacking, Devon brought up the dream yet again.
"What if the dream is telling the future? We should totally go to a club tonight and see." Devon said excitedly, picking some clothes out of her suitcase that she thought she could wear to the club.
"Are you sure? I'm kind of jetlagged and we've never been to a club before. What if something bad happens to us?" Katherine said, seemingly afraid.
"Come on dude, it's almost 9:30, we've got to decide right now and I really want to go!" Devon pleaded, getting down on her knees. "Please!"
"Fine, but you're not leaving my side for a second." Katherine said. Devon jumped up and hugged her. She abandoned her unpacking to pull out her iPhone to look up a club. Once she found one that was in walking distance from their hotel, they both got ready, Devon more scantily dressed than Katherine, and headed out.
