The Science Festival was a success so far and even John and Clara's booth were a popular stop among the visitors, especially children. The couple had spent several hours showing various mathematical tricks and they had immensely enjoyed it.

So, while Jack was giving Nan a tour of campus during lunch break, Clara took the opportunity to see the Doctor in his office. She checked the hallways first, making sure that no one was passing by before quickly running over to John's office, knocked once and then entered, surprising the occupant inside.

He arched a brow, setting down the pen he held. "Yes?"

"Just wanted to see you," she murmured.

The Doctor leaned back against the chair. "Are you sure that's a good idea – I mean someone-"

Clara locked the door in response.

"Clara?"

She straddled his lap and gave him a good snog and he automatically wrapped his arms around her, bringing her closer to him. It felt nice, good, not that he was complaining but then common sense took over. He didn't ever want to stop, but her behaviour confused him, so he gently pushed her away.

"Are you alright?"

She chuckled, leaning back a bit to allow him to breathe easier and calm his nerves. "Of course, I am."

He was now certain that there was something wrong with her. Sure, her grandmother and Jack were not anywhere near them at the moment, but it didn't explain why she would suddenly barge into his office and kiss him senseless. "So why did you… um… we… this?"

"I'll be honest," she whispered, pushing him back against the chair. "Your dad skills make you twelve times more attractive."

He licked his lips, finding her answer amusing. The door was locked so he didn't see any reason why he would want her off his lap. "Twelve times?"

"Shut up," Clara grumbled and connected her mouth with his again.

John closed his eyes, savouring the taste of her lips before remembering they were in his office.

"We won't going to shag in your office if that's what you're worried about," she stated after pulling away. "We can do that when we get home."

"It seems like it," he answered shyly.

Clara smirked. "Well, I'm not receiving any objections from down there," she commented, pointing at his bulge with her eyes.

"In case you have forgotten, I'm only human, Clara."

She could easily see through his feeble excuse. "Admit it, the thought of shagging in your office is turning you on."

"Never."

That was the end of it before the Doctor kissed her, earning a moan. He had never done this sort of thing before in his life and it felt new and exciting. The door was locked, so they wouldn't get caught like last time. Hopefully.

As Clara fumbled with his belt, a ringing noise made the couple pause. Her phone which she had discarded on the desk was buzzing.

John cleared his throat. "Do you want to get that?"

"It can wait."

"Might be your nan."

She reluctantly checked the smartphone. To her annoyance, it was the same number that tried calling her earlier in the day. "I think I'm going to block this number," she sighed, putting it on silent mode.

"Ah yes, those insurance scams interrupting you in the most inconvenient of times."

She shushed him by resuming their snogging session, unbuttoning his shirt in the process. They could spare five minutes. Nobody would know.

Clara Oswald adjusted her hair and blouse one final time before turning around to face the Doctor who was buttoning his shirt. The very one she had gotten him for Christmas. "Do I look presentable?"

"Yes," John answered, still feeling as if he was on cloud nine. He couldn't believe that he had gotten a good shag in his office of all places.

She approached him and helped him button the collar, hiding away the love bite she had given him. "The kids don't need to see that."

"And whose fault is it?" he joked.

She placed her hands on his chest. "All I heard was you moaning."

"I'm very sure you were louder," he murmured, placing a kiss on her cheek.

Clara bit her bottom lip. "I can prove you wrong when we get home," she whispered. "But first thing's first – work."

The Doctor watched as she stuck her head out the door, checking to see if the hallway was clear. She glanced at him and flashed him a flirtatious smile before leaving the office.

Just as she entered hers, the phone in her pocket began buzzing again. Having lost her patience, she decided to answer the call once and fall all and tell Danny to never bother her again.

"Clara… I know you're very angry and you have every right to be, but just give me thirty seconds to apologise – I'm sorry."

"Danny, please stop trying to call me," she said as politely as possible.

"I have so much to say to you and please, I'm at your university right now."

"What?!" she exclaimed in surprise before lowering her voice. "What do you mean you're here?"

"I think I'm heading in the right direction to your office."

"You can't-"

"Please, Clara, I am so sorry for treating you the way I did – I got angry and I was jealous," he explained. "I'm almost here," he stated before hanging up.

Clara stared at the blank wall. Why did everything have to turn upside down the moment she's experiencing happiness. Danny had broken up with her and now he's practically trying to get her back. She would have none of it, especially since he came unannounced.

A knock was heard, and she stormed outside.

"What are you doing here?" she hissed. If he had wanted to discuss things, he could have sent her a text message first instead of simply phoning her. They could have met at a café or restaurant – not her bloody workplace.

Danny managed an apologetic smile, holding up a small bouquet of flowers.

It didn't calm her down one bit as she quickly glanced at the Doctor's office.

"Can we talk in your office?" he asked.

"No," she replied defensively before realising that people could probably hear them in the hallway. "I mean yes… no."

She didn't want to be alone with him in her cramped workspace.

"You ended things with me and now you're showing up with flowers and an apology at work?" she demanded, trying to control her voice and anger.

Danny lowered the flowers. "To be fair, I only said we needed to take a break – we took a break."

"It doesn't matter – we ended things that day and please stop bothering me," she sighed. "Your thirty seconds are up."

He caught her arm in a plea to get her attention. "All I asked was for some time to think."

"Let go of me."

"You should do what she says," a Scottish voice growled, eyes blazing with anger and a hint of jealousy. He had been sitting in his office quietly when he heard what sounded like an escalating argument.

Danny glanced at him before releasing her.

"Are you alright?" he asked in a gentle tone.

Clara nodded. "Fine," she said meekly. "Thanks."

Danny waited for the Doctor to leave but he never did. He had his feet planted firmly on the ground and arms crossed. "Isn't this the bloke you hate?" he asked Clara. The former soldier had heard enough stories to recognise him. Besides, the plaid trousers were a dead giveaway.

"Look, Danny, just leave."

He was about to open his mouth, make a point when the Doctor interrupted him. "I think you should do what she says," he stated in a low voice.

"This has nothing to do with you," Danny grunted. "I just want to have a talk with my girlfriend."

"I am not your girlfriend," Clara hissed, face red. Oh, God. She could tell John had so many questions running around his head.

"She's saying otherwise," the Doctor retorted. "It's best if you leave her alone."

Danny pursed his lips. "Stay out of this."

"You should do what he says," Clara suggested calmly.

The school teacher couldn't quite believe what he was hearing. Was she really siding with the man she dislikes so much? "Why are you on his side?" he whined. "What did I miss these past few months?"

"What's he talking about?" John inquired. He had heard everything from the beginning and he just felt more and more confused.

Clara wanted to do nothing more than to allow the ground beneath her to swallow her. Why did her perfect day have to be ruined? "It's none of your business, Danny and I thought I made it clear that I don't want to talk to you."

Danny stared back and forth between Clara and the Doctor, putting the pieces together. "You slept with him didn't you?" he demanded.

"What if she did?" John growled, taking a few steps forward. "She told you to leave and you have yet to do that."

Danny faced him. "You slept with my girlfriend."

"I am not your girlfriend, Danny," Clara repeated. "Not since you left."

Danny Pink could accept the fact that Clara had broken up with him, but he couldn't quite comprehend how the man she loathes managed to sleep with her. It boiled his blood. "We were on a break!"

"And that my dear lady is a tour of this fine university," Jack concluded to Nan as they walked down the hallway. The smile disappeared from his face when he saw the three individuals. "What's going on?"

Nan had seen a photo of her granddaughter's former partner before. She had received it from Clara during New Year the previous year, so she was just as shocked to see him in the flesh, glaring at her future grandson-in-law.

"This man is just leaving," John said, shooting daggers at Danny.

The next thing he knew, Danny tried to throw a punch at him before he swiftly moved to one side, watching as the former soldier fell to the ground.

"John!" Clara cried, rushing over to his side.

Jack decided to step in by standing between the two men. He faced Danny. "Leave," he ordered in a serious manner. "You're causing a ruckus here with my friends."

Danny stood up, one hand still gripping the bouquet of flowers. He stared at Clara for a brief second, eyes filled with anger and sadness before turning around and quietly leaving.

"What was that all about?" Jack wondered.

"I could ask the same question," the Doctor agreed, glancing at Clara.

She pressed her lips together. "I can explain."

Jack then squinted his eyes, wondering why his two colleagues were staring at each other oddly. "Are… are you two together?"

There was silence for a few seconds before Clara gave a nod to John.

"They are," Nan confirmed, getting tired of waiting. She felt like rolling her eyes to the back of her head.

Jack stared at the Doctor and then Clara before a huge grin broke out. "You're finally together!" he screamed happily. "Yes – miracles happen, baby!"

"You showed me faith is not blind, I don't need wings to help me fly miracles happen once in a while when you believe," he sang.

The couple merely looked at him in disbelief as Nan settled down on one of the chairs in the hallway.

"This is wonderful!" he continued. "How long?"

"Two months," Clara replied.

The smile on Jack's face immediately disappeared. "Two months?" he repeated. "You've been together for that long and you didn't bother to tell me?!"

"Hang on, I thought you'd be happy about this?" John asked, confused.

"I am, but how could you hide such a thing from me?" Jack demanded sadly before glancing at Nan. "We shared so many plans together about your future great-grandchildren," he murmured before storming off. "And all those things about these two giving heart eyes to each other."

Nan stood up. If Jack was her grandson, she would have given him a good whack to the head. Such a silly man. "He'll be fine and while he calms down, but I think the two of you need to talk," she suggested, leaving to find wherever Jack had run off to.

Clara avoided eye contact with the Doctor.

"Is it true what he said?" he asked quietly once her grandmother was out of earshot. "You're just taking a break?"

She had never seen him so upset and hurt before. It would seem that she really messed up this time.

Clara opened her mouth to speak but no words came out. She had been under the impression Danny had broken up with her. She had been angry and upset and didn't quite process his words carefully.

"I think I'm going to go back to the booth," John announced and left in a hurry, not wanting to face her for the time being.
