DEO

Winn had been running any program he could think of to figure out what kind of energy the signature could be. All he could tell was this energy wasn't harming anything. As he was staring at his screen another alert popped up. In the center of the unknown energy field, someone was initiating some sort of scan.

"Hey J'onn," Winn called.

"What is it, agent Schott?" J'onn asked coming over.

"There is a scanning signal coming from the middle of the unknown energy field," Winn said, his voice becoming a little anxious.

"Agent Danvers," J'onn called.

"What is it, sir?" She said walking over.

"I want you to lead a team and investigate what is causing that signal. It's probably what's causing that energy field as well."

"On it."

Within minutes Alex Danvers and her team were combing an alleyway for the source of this signal. Winn was with her with some sort of device used to pinpoint the location. They rounded a corner in the alleyway and Winn's machine started to beep.

"Whoa," Winn said checking the readings on his device, "We're getting close."

The more they moved along the closer the beeps got to each other until they got to a big blue box, then Winn's device made a screeching noise.

"The signal is coming from in there."

"Are you sure?" Alex asked, wondering what type of energy a big blue police box could be emitting.

"Positive."

Alex motioned for the soldiers around her to surround the box with guns at the ready. Before she could get close to the box a man in a brown suit and lighter brown jacket came out of the box, followed by a young woman wearing a purple leather jacket and jeans.

"Put your hands where I can see them," Alex shouted and they both did so. The man looked confused, while the woman looked scared, although she was trying to hide it.

"Are you the owners of the police box?" Alex asked.

"That would be me," The man replied with a British accent, "And I really don't like guns, could you put them down?"

Alex contemplated doing that-they certainly didn't seem like a threat, but she would have to search them for weapons nonetheless.

"Are you carrying any weapons?" Alex asked her gun still trained on the man.

"No, I don't like weapons and I like them even less when they're pointed at me and my friend," he said.

Alex lowered her gun, "I believe you but I still have to search you," Then she nodded at two of her guys to go and search them. The man seemed to be a little more at ease but the woman still looked scared.

Alex turned around to look at Winn, "Find anything?"

"No, but the scanner has stopped, I need to get inside to find out what we're dealing with."

Alex turned around to see that no weapons had been found on the suspects.

"If you don't mind me asking," the man started, "Who are you?"

"I'm agent Alex Danvers with the department of extranormal operations. Who are you?"

"I'm Doctor John Smith and this here is Martha Jones."

"Well then, Doctor Smith and Ms. Jones you're coming with us," Alex said turning towards her agents, "You four stay here with agent Schott. You three come with me." Alex turned around and walked back out of the alleyway.

"You be careful with her," The Doctor said pointing to Winn as he was scanning the TARDIS.

Winn wasn't really sure what to be careful of after all it was just a big wooden box and just ignored the comment.

CatCo

Kara was sitting at her desk listening to her interview with the British tourists; they said lovely things about her and it made her smile. She had lost track of how many times she had listened to it. She was about to restart the recording when her phone went off. It was Alex.

"Hey what's up?" Kara asked with a bit of a giggle.

"Were the people you interviewed Dr. John Smith and Martha Jones?"

"Yeah, why?"

"We have reason to believe they're behind the strange energy signature."

"I'm on my way," Kara said angrily, how could people who said such nice things about her be planning something sinister. She angrily packed up her things and headed towards the DEO.

DEO

The Doctor and Martha were lead into the DEO by Alex and taken into an interrogation room. They sat there for a bit while Alex went to get J'onn.

"We have two suspects in the interrogation room."

"Where did you find them?"

"They came out of the thing that was emitting the strange energy."

"What was this thing?"

"That's the strange thing, it was a big blue wooden police box."

"That is strange, Alex. Let's go talk to them."

Alex and J'onn walked into the interrogation room.

"Don't worry Martha, everything will be fine."

"Every time you say that Doctor, things aren't fine for a while!"

"Of course they are!"

"What about that museum incident?"

"Well..." The Doctor said rubbing his chin.

J'onn looked over at Alex thinking this was a good time to intervene.

"I'm Director J'onn J'onzz of the DEO. You've already meet agent Danvers," J'onn said introducing himself with the name of the human he has shapeshifted into.

"Yes, we have. I'm Doctor John Smith and this is the lovely Martha Jones. Why did you bring us here?" The Doctor said trying to be friendly.

"So you can answer a few questions," J'onn said in a very stern voice.

"If you wanted to ask us questions, you could have just asked us in a cafe like that reporter did," Martha said. Alex made a mental note to not underestimate Martha, she seems to be just as smart as Doctor John Smith.

"See Martha, never trust acronyms. You never know what they're hiding." Martha just rolled her eyes.

"I don't think you understand the seriousness of the situation, Mr. Smith." J'onn was pretty sure it was a fake name and what Mr. Smith said next confirmed it.

"It's just the Doctor." J'onn looked a little confused, "I go by the Doctor."

"So people call you 'Doctor'?" Alex asked.

"Yeah," He said nodding.

"So why are we here?" Martha asked, trying to get out of here as quickly as she could.

"We discovered strange energy coming from your police box," J'onn said crossing his arms.

"You did?" The Doctor said with a surprised and confused look on his face, "There shouldn't be any energy coming from..." The Doctor slapped his forehead, "That's why we've been having to fuel up so often! The engines haven't been shutting properly and leaking Artron energy!"

"Artron energy, is it harmful?" Alex asked.

"No! Not at all!" The Doctor said defensively.

"I've never heard of Artron energy, what is it?" J'onn asked.

"It's time travel energy," The Doctor said cautiously.

"You're a time traveller," Alex said, "What year are you from?"

"I don't know what year he's from but I'm from 2007," Martha said with a bit of a chuckle. The room went silent, Alex was trying to take in the fact that they were time travellers with a police box time machine. But J'onn was trying to validate the story, he could read Martha's mind and knew she was telling the truth but he couldn't read the Doctor's mind. Naturally, J'onn pushed a little harder but he was pushed back with just as much force. He looked over at the Doctor to see him concentrating. A normal human shouldn't have been able to resist his telepathy, perhaps this Doctor really was from the future.

The Doctor was aware of someone trying to read his mind and he didn't like it, no way was Alex doing it, she was checking something on her phone and he was pretty sure she was human anyway. It obviously wasn't Martha, but the mind reader probably already read her mind. That only left J'onn, no human could possess those abilities, he had to be alien. Then some words came to mind, those of an old friend. A door, once opened, one may step through in either direction. If J'onn got into his mind he could step through into his. But he wasn't going to let that happen, he had too many secrets to be kept safe.
