A/N Thank you guys for all of your kind words! I hope you enjoy this one and tell me what you think!


Alleyway

Winn had been trying to get into the police box for what felt like forever. The door read pull to open but when he pulled it, it didn't budge. Then he pushed it with no luck either. Then he tried picking the lock. The lock was a lot more complicated than it looked, so Winn got one of the soldiers to shoot the lock. Nothing, not a scratch... and it's just a wooden box! Winn was getting fed up; he should be able to get into a wooden box without any problems. He grabbed an alien artifact from his bag. He had been trying to figure exactly what it did but he knew it could cut through very dense materials. To make sure it was working he took a bucket from a nearby dumpster and cut several holes in it like the Flex Seal commercials but he didn't have any Flex Seal with him to fix the bucket. Too bad he didn't have a boat.

He went up to the box and decided to cut around the lock. But when he used it there wasn't a scratch on the box, not a scorch mark, not a small indentation, nothing. He let out a sigh; he was trying so hard not to get frustrated but he was running out of ideas to get into the box. He let out a yelp when his phone went off and fumbled for it.

"Hey, Alex, what's up?" Winn said into the phone.

"I'm fine. You're on speaker with J'onn. What did you find in the box?"

"That's the problem. I can't get into the box."

"The box is made of wood Winn. This better not be a joke."

"Seriously, I can't get into the box."

"Have you just been clowning around for the past hour agent Schott?" J'onn asked, he sounded angry.

"No. The lock wouldn't budge when we tried to pick it. Even the alien lock picker couldn't do it. Then I used the unidentified alien artifact on the box and it didn't leave a scratch."

"Which unidentified artifact?"

"The destructive one you told me shouldn't leave the DEO."

There was a moment of silence. Winn was waiting for J'onn to yell at him or something. But J'onn was surprised that the unidentified artifact couldn't break into the box.

"Winn, report back to the DEO. You can get back to the box later."

"Okay-" Then J'onn hung up. Winn sighed, "Let's head back to the DEO J'onn's orders."

DEO

J'onn hung up the phone and sighed.

"J'onn what's wrong?" Alex asked, genuinely concerned.

"Winn should have been able to get into the box if it were just a box. I don't know what it is and I can't read the Doctor's mind to figure it out."

"Then we should be in there figuring out why," Alex said about to head back into the interrogation room.

"No, I can read Martha's mind, she's telling the truth and believes what the Doctor was saying to be true."

"Then what do we do with them?"

"I don't know, but I'm almost certain the Doctor isn't human. We also have to figure out what is hovering above Earth and deal with that."

Interrogation Room

"Do you think they'll let us out?" Martha asked as the Doctor was pacing the room.

"They'll let you go. I think J'onn has figured out that I'm not entirely human. Of course, neither is he but..." The Doctor trailed off.

"If J'onn's not human is he a threat?"

"No. He tried reading my mind but I have stronger physic abilities than humans so I pushed him back."

"Are you saying he read my mind to?"

"Yeah. But without physical contact, it is extremely hard to dig through memories. He was probably checking to see if you were telling the truth. Can you do me a favour?" Martha nodded, "Don't tell them what species I am."

"Why?"

"Some species will try to kill me on the spot and I want to make sure J'onn isn't one of those."

"I don't get it, Doctor, you're a good man."

"Not everyone sees me that way Martha, I've done some horrible things that I'd rather forget."

Martha was silent, she knew that the Doctor had a checkered past but she wasn't about to push the Doctor into telling her.

Control Room

Supergirl had just landed and stormed in, she was pissed off at John and Martha for saying nice things about her, then bringing unknown energy into the city. She was about to give them a piece of her mind.

"Supergirl," J'onn called out.

"Where are they?" She asked sounding extremely pissed off.

"Are you alright?" J'onn asked.

"I just need to speak with them."

"Not like that you're not," J'onn said. Supergirl looked like she was about to challenge J'onn when Alex, who had been observing the shouting match came over.

"Kara. Can I have a word?" Alex motioned to the empty medical room. Kara reluctantly followed Alex into the room.

"What?" Kara asked having calmed down only a little bit.

"Why are you so upset?"

"I saved those two, then interviewed them and now look where they are! They were probably planning to destroy the city!" Kara said melting down.

"Kara," Alex said in her kind big sister voice, "J'onn and I interviewed them. They honestly didn't know that their ship was leaking Artron energy. They also said it was harmless."

"Oh thank God," Kara breathed a sigh of relief, "Wait. Did you say Artron energy?"

"Yeah, why?"

"Artron energy was rumoured to be a time travelling energy. I think they started experimenting with some on Krypton."

"Well, that fits their story."

"They're time travellers?"

"We believe so. Martha said she is from 2007."

"Really!" Kara looked excited now, "Now I have to go talk to them!" Kara said turning around.

"Promise you'll be gentle."

"I promise," Kara said with a wide grin. She was getting ready to become the stoic Supergirl and not Kara Danvers.

While Alex and Kara were having a sisterly conversation Winn returned from the alleyway. He walked into the room ashamed that he couldn't get into a wooden box.

"Give it here, Winn," J'onn asked and Winn reluctantly handed the unidentified alien artifact to him, "I'm surprised that this didn't work on a wooden box."

"I tried everything I could think of and nothing left a scratch. Did they tell you what's inside the box?"

"I'm pretty sure it's a time machine of some sort."

"Really?! Awesome!" Winn said with his eyes lighting up, "Can I go talk to them to figure out how to get inside?"

J'onn looked closely at Winn, there was no saying no to him, "Fine, but be quick; we have other matters at hand."

"Thank you!" Winn said practically running towards the interrogation room.

"Hey Winn," Kara called, "Where are you headed?"

"To go talk to our friends with the blue box. So are you, aren't you?"

"Yeah, we can go together."

Kara and Winn walked down the hallway. They didn't notice Alex going to the surveillance room to listen in on their conversation.
