Nothing could be heard in the Foundry apart from the banging of the pipes and the thousand feet stomping above. Felicity Smoak was completely immersed in the task at hand – Oliver had asked her to try and hack into the hospital's security. Some drugs had been reported missing and Oliver was concerned a new Count Vertigo might have turned up.

Her quick and trained fingers allowed her to complete the task in the blink of an eye, and the footage appeared in front of her lit up face. As far as she could see, the place was deserted, apart from the occasional wandering nurse and a couple of security guards. Nothing to be worried about.

She picked up her phone and dialed Oliver's number to tell him – he tended to worry too much.

"Felicity," he answered immediately.

"I hacked into the hospital's security cameras. Everything seems fine."

"Are you positive?" asked Oliver, a hint of hope in his voice.

"Abso-toot-ly! I mean… yes, I am positive" Felicity stuttered. Talking to Oliver still made her nervous sometimes.

"Okay, then. Run the scanner just in case and try to see if you can get something useful from the footage."

"Roger that, boss. Be safe." She couldn't help but notice the pit in her stomach – that mission was way too dangerous, but she knew telling him that would make no good. He needed to be focused.

"You too." And he hung up.

Felicity sighed out loud, and the sound reverberated throughout the whole room. She really didn't like being down there all on her own, unable to get out in the field and help the Arrow team, as she liked to call them. Even Roy, who had gotten there after her, was able to be out there thanks to the Mirakuru. And Sara as well. She really wished she would've learned how to fight. She had loved getting that new scar.

Remembering her vital task within the team, Felicity went on to check the scanner, just like Oliver had told her to. It was a kind of routine, just to be safe, so she left it searching and searched for her iPod to listen to some audio books.

Before she could even switch it on, a beeping startled her. She ran to the monitor only to find out the hospital was as peaceful as it was before, but it was definitely the scanner. She frowned.

"That's weird. The scanner's never been wrong before…"

Immediately she found an extra picture on the screen, like someone had suddenly introduced a new electronic device out of the blue. But no sooner had she tried to hack into it than it disappeared as quickly as it had turned up.

Felicity was starting to get nervous. She checked in her mind every kind of glitch or virus that could've caused the scanner to go crazy, but she knew deep inside that this wasn't just a computer problem.

Five seconds after the picture had disappeared from her screen, the alarm on the wall went off. A shiver ran down her spine – that could only mean that someone had broken inside the base, and this time she was all by herself. And moreover, the Foundry went into lockdown mode, so she couldn't escape.

Frightened, she rushed to the corner where they kept the weapons, wondering what would take her longer – learning how to use a bow or finding one of Diggle's guns. Probably the first, so she started searching.

And then it came. An intermittent whooshing sound, so loud and clear she forgot about the noise above her head. Along with the sound came a bright light, and suddenly a big, blue box with the word 'POLICE' written on it started materializing.

"It… it can't be…" muttered Felicity. If she hadn't known it was impossible, she would have sworn that was the TARDIS, the time machine used on one of her favorite shows, Doctor Who.

The box finally went silent and Felicity stared at it with her mouth wide open, unable to move a muscle. She was in such a shock that she couldn't even react when the door of the blue box opened and a tall man with grey hair and dark clothes stepped out of it, mumbling something with an angry tone.

"…can't even keep their hands still," said the mysterious man. "And who are you?" he asked, looking at Felicity.

She had suddenly forgotten how to make words, how to speak.

"Oh, my goodness, have I run into a deaf human now?!" he almost shouted, throwing his arms into the air. "WHO. ARE. YOU?! And why the hell have you hacked into my TARDIS?! Look at what you've done! Humans," he hissed.

Still no answer from her.

"Hello! Are you in there?" he asked, tapping Felicity's head with his index finger. "As interesting as I find it to talk to myself given my spectacular mind, I need answers!"

She finally seemed to wake up. "Right! Um… Nice to meet you! I'm… uh… I'm Felicity. Felicity Smoak. And you are…?"

"The Doctor."

"Sure," she laughed. "Okay, I'll play along. Doctor Who?"

"Just the Doctor. Can you tell me where we are, precisely?" he asked, frowning seriously after Felicity's laugh.

"Okay, you can drop it now," she said, chuckling lightly.

He just frowned again, staring at Felicity confused.

"No, seriously, it's all very funny and your props are outstanding but you need to leave, you're not allowed in here."

Before the man who called himself the Doctor could reply, she started walking towards him in order to lead him to the exit. But the moment she did, he reached into his jacket and took a metallic black and white stick with a green end, pointing it at her. Felicity gasped in awe.

"That's a sonic screwdriver! Oh, my God, I so wanted to get one. But they sell out so quickly it's almost impossible to find one at an affordable price. Where did you get yours?" Felicity babbled, letting her inner fangirl show.

The so-called Doctor paused. "How do you know what a sonic screwdriver is?" he said, lowering the aforementioned device.

"Tsk. Because I'm a Whovian! I could watch the show all day, all night, all week, just give me episodes and more episodes and… phew! I finish them in the blink of an eye! No, wait. Because you can't blink. Ha! See what I did there? Whovian humor." She was way too excited to share her geekiness with someone who finally understood it. That wasn't very common down there.

"I'm… Erm…" The Doctor was struggling to find the words. This had never happened before. No one he had ever run into knew so much about him and his life. "Sorry, you said you're a what?"

"A Whovian, of course!" she said excitedly.

"And what exactly is that?" the Doctor asked cautiously.

"You have a TARDIS and a sonic screwdriver and you don't know what a Whovian is? Have you been living under a rock or something?"

"I did once, there was this planet where… Well, doesn't matter. The important thing here is – why did you hack into my TARDIS?"

Felicity opened her eyes widely. "You mean… that's what appeared on my scanner? At the hospital?"

"Yes!" the Doctor exclaimed. "I was following some strange signal and then suddenly you took me out of there! How?!"

"Well, as I usually say, 'Code-breaker' is my second name," she said with a grin. "Whoa! Wait a second! You're not actually trying to tell me… that this TARDIS… works, are you?" she muttered, too shocked to speak normally.

"Of course I am, haven't you been listening?! What are you, a human pudding brain?" the Doctor answered, clearly offended by her remark.

"But… But… But that's not possible! It's just a fiction show! Just a normal, British show written by Steven Moffat! It just can't be real…" Felicity started wandering up and down the room, talking to herself.

The Doctor rolled his eyes, took her by the arm and led her to the TARDIS. He opened the door and before her eyes appeared a two-story console room in which she could see dozens of levers, several railings and even a bookcase.

As soon as the Doctor released her arm, Felicity fainted, hitting the floor loudly.
