A/N: This isn't to be confused with the upcoming episode. I just had to write this down because my head was going bonkers, bursting with many ideas. Happy 50th Dr. Who!

He who crosses over the line.

Travels beyond the great divide.

The two parts will intertwine.

As the two are from the same side.

Clara and the Doctor landed back from Trenzalore as they were talking about where to go next.

"You know Clara," The Doctor states, "We should visit the planet of Aquarius. It'll be a great splash and the kids would enjoy it. Come, on and think about the fun we'll have."

"Mmm," she ponders in thought as she looks around, "I'm not sure. I don't want the kids to be eaten by a big two-headed alien shark on the beach."

"They evolved far beyond that," The Doctor smiles.

Both exit the TARDIS as they walk inside the house. The Doctor couldn't help but look around the place and then he went upstairs to Clara's room; where he'd found the 101 places book. He opens it and finds a leaf and smiles from it. He turns the page and sees a small sheet of paper, he opens it and sees the paper had his number on it.

'This is the number Clara used to call me about the whole Wi-Fi incident, but how did she get it? Who was the woman?' The Doctor thought deeply as he pulled out his trusty sonic screwdriver to study the paper.

He pulls it back and reads the screwdriver, "Hmm. Interesting... There's no prints of another person, no DNA signature and it's not even reading the writing style; the only thing here are Clara's prints."

He smiles widely, "This is going to be fun."

"Doctor, where are you? Doctor!" he hears Clara shout loudly.

"I'm up here!" he screams back at her as he hears her footsteps coming swiftly upstairs to her room.

"Why are you in my room?" she asks the Doctor.

She pulls the paper, "I remember this, this is the number I used to call you."

The Doctor asks her seriously, "Who was the woman that gave you this? What was her name?"

"I don't know," she replies, "she never gave me her name. She just wrote it down and gave it to me."

"Then where is the shop?" he asks Clara as she crosses her arms with a smirk, "Okay. I'll show you where the shop is and you can talk to her yourself."

She goes downstairs as The Doctor smirks.

Few minutes later...

Both Clara and The Doctor were riding on the motorcycle as Clara was giving him directions of where the shop was.

"Turn right and head straight down this road..." The Doctor follows her directions and then she stops as she looks around.

"Stop. Stop! Stop Doctor! Doctor, stop!" she screams as The Doctor stops the motorcycle. She takes off her helmet and jumps off the motorcycle.

"I-I don't understand," she asks as she looks around.

She walks down the block and looks at the buildings close as The Doctor comments, "Clara, are you sure this place was here?"

"I'm telling you it's real," she retorts as she walks, "I went there everyday when the kids said they were having some internet problems."

"Then where is it?" he asks her.

"I don't get it. I know where it is. It supposed to be around here. I think," she said as she looks around.

"I-I don't know where it is. I don't understand, it was here. It was just here. I don't know where it is. Where is it?" she asks as she closes her eyes to remember.

She shakes her head in frustation, "Grr. I don't understand. Why can't I find that shop? Or remember it?"

"Because it's gone," The Doctor explains.

"Gone? What do you mean gone?" Clara turns to him and asks.

"Well...Not really gone," he replies.

"Then where is it? I can't find it anywhere and I can't remember it either," she admits.

"Why don't I remember about it?" she asks the Doctor.

"Clara-" he speaks but she interjects, "No, Doctor you don't understand. It has always been there. There's always been a shop here."

"Has there? Think about it. Think real hard about it Clara," the Doctor tells her.

She comments, "Of course. Yes, yes of course... Wait...no. I-I don't know. I can't remember."

The Doctor replies, "Perception filter. It tricks your memory. It can even..."

He stops as he looks at something and Clara sees his face. She looks at the direction he was staring at.

"Doctor? What? What is it? What do you see?" she asks as he turns his head to her.

"Huh. Oh...Um nothing. Just looking," he answers.

"No...you saw something," she states as she turns to the direction he was looking before.

She walks over to the spot and speaks, "Funny. It's like... It's like there's something there, but I don't want to know of it."

She narrows her eyes intensely as she thinks she sees an image of a person, "What?"

"Clara, Clara what is it?" The Doctor asks as she turns back to him and then back to the spot.

"I... I think I saw something," she admits.

"What? What did you see?" he asks her.

"I-I don't know. I couldn't see it clearly," she confesses as she shakes her head.

"It's probably the perception filter. It just shifts your perception a tiny little bit, but that small bit makes you unnoticed," he explains.

"You mean you can turn invisible?" she questions him.

"No, just unnoticed. That's all, but why would someone take a shop or whatever it was away from here?" the Doctor asks as he looks around.

"What's so special here?" he asks as he looks around.
