When John came to work in the wee hours of the morning (the perk of having the safe house close to the workplace), he noticed a small white envelope sitting on his desk and knew that it was the package he was expecting from Dave.

Without much thought, he proceeded to tear the envelope which contained an SD card before switching on the computer and plugging the storage device in.

He was the only person in the office at the moment, so there was no need for him to be discreet. There were several files from the SD card which contained everything from Davros' name to his arrest back in 1985.

"Early start, boss?"

John looked up. It was Dylan who had just come into the office. He was sure that Dylan was the one who sent him the intel.

"Don't think I've ever seen you this early."

Dylan shrugged. "The team is working extra hard, so I thought that I might as well do the same."

The DCS set his eyes back on the bright screen and began reading more about Davros. He found it ironic that the man was on MI5's watch list and yet he managed to order a drive-by shooting.

Aside from that, there wasn't much he didn't know about from what Clara had told him. Even they had limited intel on him.

"You know," Donna's shrill voice tore him from his thoughts. "When we said take a few days off, we actually meant a few days as in two or three."

Bloody hell. He had completely forgotten about the ensuing nagging from Donna. "It wouldn't hurt to have an extra pair of hands."

"Yeah, go on, then, detective boy," Donna said. "Come up with feeble excuses!"

"Who angered Donna, I wonder," Aidan whispered to Rena sarcastically as both officers entered the room.

Rena shook her head before settling in her seat and waking up the PC. She left the computer running the previous night to allow it to finish its search on the database for the car they were looking for.

She checked the result and indeed, it was the car they that had been trying to identify.

"I got a match," she announced. A second later, the entire team was gathered around her. "Reported stolen last week."

John nodded. "Rena, take Aidan with you and talk to the owner," he instructed. "See if you can find out more about this."

As he was returning to his desk, he received another nagging from Donna. "Once your shift is over, I want you out of his building and back at home."

John rolled his eyes. He sometimes wondered if Donna was actually the commander and that she's just going undercover to see if people under her were doing her job. He grumbled in response before checking his phone for any messages from his wife.

If there was one thing that they had agreed upon, it was that she would text him every two hours to inform him that all was fine.

One thing that they had learned from her father is that Davros has people on the Met working for him too and it could be anybody, so they weren't taking any chances.

'Come to the safehouse now.'

That was all it took for John to jump from his seat, grab his jacket and bolt out of the office.

"Oi!" Donna growled as the DCS nearly collided with her.

John ignored her and sprinted away.

"What the…," Aidan began.

Dylan had a feeling that something was wrong and decided to follow his boss.

While Clara didn't mind being stuck in a safe house, for the time being, she was growing increasingly bored and tired of being stuck in the bedroom.

It was a good reason for her to go downstairs and acquaint herself with the very people protecting her and that was exactly what she did, though she was surprised to find only one officer.

"Mrs Smith," Isaac greeted. "Is everything ok?"

"Yep," she assured. "Just decided to explore a bit."

"Not much to explore I'm afraid," he chuckled.

The schoolteacher shrugged. "Better than being cooped up upstairs."

Isaac said nothing as he returned to his smartphone.

The realisation struck her at that moment. As far as she was aware, there were supposed to be two officers who were on duty. "I thought there were two of you?"

"Bradley went out to buy batteries for the TV remote."

Clara nodded in acknowledgement before entering the kitchen to make herself a drink. "Hot chocolate?" she offered, turning around. That was when she noticed something odd about the smartphone. From the angle he was holding it, she could clearly see the symbol etched on the case. Daleks.

She knew she had to remain calm and swallowed the lump in her throat. "How long have you been working as a police officer?" she inquired, setting the kettle on the stove.

"About six years, Mrs Smith."

She could feel her hand shaking and hid her hand behind her back. She was surprised to see him staring at her with a strange look.

"You look ill, Mrs Smith."

"Probably because I'm hungry," she replied, trying her best to not look down at the symbol. "Which reminds me, I think we should order something."

"I'm sure Bradley can do that when he gets here."

"I don't see what difference it makes," she told him before quickly unlocking her phone and pretending to scroll up and down when in actuality, she was typing a message to John.

"It's for your own safety, Mrs Smith," Isaac insisted, his tone sounded annoyed this time, lowering his hands which held the electronic device.

She stalled the conversation for another minute or two until her eyes followed the movement of the smartphone. Big mistake. She knew he caught her.

The kettle whistled and Clara grabbed it before tossing it at the man, hot water spilling all over him and he yelled and hissed in pain while she ran past him and up the staircase.

She managed to make it to the bedroom and slamming the door in Isaac's face and hearing a crack. Her aunt's training actually paid off.

"Fuck!"

She took several steps back while looking around the room for anything that can be used as a weapon.

The door banged repeatedly as he tried to break it and she knew she was running out of time. A gunshot was heard, startling her. He was probably shooting at the lock.

Clara grabbed the metal suitcase next to the wall and hid behind the door, waiting for the man to walk it.

The door swung open angrily and the moment she spotted him, she brought the suitcase down to him, hitting him on the back of the head and body repeatedly until Isaac was unconscious. She kicked him for good measure before running out of the bedroom and shutting the door.

"Clara!" John yelled from downstairs. "Clara!"

She waited for him to come to her. She could hear his every single step, which was as loud as her breathing.

"Clara," her husband murmured before embracing her tightly.

Dylan followed after a few seconds before making eye contact with her and checking on Isaac. The DCI opened the door and discovered that the man was unconscious. He wanted nothing more than to shoot him in the head.

Clara finally dropped the suitcase and hugged John, making sure that it was indeed him.

Dylan handcuffed the criminal before forcing him to stand, earning a pained groan. "I'll take him straight to Scotland Yard."

Sirens could be heard, and John suddenly had a feeling of déjà vu.

"Where did you learn to fight like that?" he asked his wife quietly, both slowly sinking to the floor.

"Aunt Vastra taught me self-defence when I was fourteen."

He kissed her hair, thanking whoever was watching over his wife. He couldn't imagine what would have happened if things had taken a different turn.

"Can we go back to our home?" she asked. "This safe house is no safer than our own home and I doubt that the new one will be any different."

"I was thinking the same thing," the detective told her. The only difference is that there would be more police officers present, those who he trusts completely. "I can't guarantee it, but I'll try my best."

By the time Dylan returned to Scotland Yard, the entire had heard what had happened at the same house.

They silently watched as the DCI dragged Isaac into an interrogation room, face hard and eyes cold.

Aidan stood up to volunteer to interrogate the suspect, but he was stopped by Rena. "I'd let him release his pent-up anger first."

Dylan shoved Isaac into a chair before locking the door. "You fucking cunt."

Isaac breathed heavily, staring at the wall. "That the best you got?"

Dylan delivered a punch to his face. "I'm just getting started."

Fifteen minutes later, Isaac suffered a broken nose, a busted lip and a black eye, though he wasn't willing to talk just yet.

"What were you going to do to her?" he asked. "What did Davros tell you?"

Silence.

Dylan punched the man's stomach, earning a groan. "Start talking, Wilson – you've got nothing to lose after losing everything today."

Isaac lowered his head. "Spy on her."

"You were going to kill her."

The man shook his head. "Davros… said she and the baby would be a bargaining chip."

Dylan paused as the news shocked him. Clara or John never announced that they were expecting. "How do you know she's pregnant?"

"She was avoiding certain foods and drinks," Isaac explained, gasping for air. "Overheard them talking too."

He wondered if Dave knew about this. Probably unaware of it. Without another word, he marched out of the room, leaving the door wide open as he passed by Rena. "He's yours to deal with."

Dylan quickly made his way to the back of the building, making sure that he was secluded and that no one was around. He dialled a number and waited for the person on the other end to answer the call.

"This had better be good."

"Afraid not, boss," the DCI said to Dave. "One of the officers at the safehouse is a spy."

Dave was silent for a second before something being punched was heard. "What do you mean he's a spy?"

Dylan silently prayed for a before he began explaining the events that occurred just an hour ago. By the time he finished, he could tell that his boss is fuming. Well, fuming would be an understatement.

"I would advise you to calm down first, sir."

"To hell with that!" Dave roared. "What happens now?"

"I'm not sure, boss, since they're still at the same house."

"Go back then and ask them," the man instructed. "I want to know everything and once they've moved to a different safehouse, I want to place my men there."

It then occurred to Dylan that he has yet to inform Dave that Clara is pregnant. As much as he was obliged to share the news, he decided that it wasn't his place to do it. If they were hiding it, then he was sure they did it for good reason.

"Once that's done, I want you at the club so we can deal with Davros once and for all."

"Boss?"

"The meeting is at three."

Dave then hung up before the DCI could reason with him not to act irrationally.
