Deciding to keep away from the main city centre, where they might bump into their overzealous friend, The Doctor and Yaz decided to head back in the direction of Yaz's flat. Since they were out so late, it was practically early morning. Yaz had requested that they watch the sunrise. The Doctor, being the softy she was, couldn't say no to those big, beautiful eyes.

They sat side by side on the bench overlooking the city. The night was beginning to catch up with them, but they were still wired. Too excited for sleep, when there were so many new revelations to explore. They still hadn't really talked properly, but their actions spoke enough for one night. It had been a turbulent few hours.

'Well, it's certainly been a ride tonight,' Yaz commented, gazing out at her city. The Doctor nodded beside her, noting the thin orange line that was beginning to appear over the horizon. She'd always loved sunrises. They marked the dawn of a new day, new beginnings. Sunsets, on the other hand, made her sad. Everything ends. And she definitely hated endings.

But right now, like the new day, she was on the verge of a new beginning. With Yaz.

She knew it was risky. She'd even told herself earlier that evening that she would never get involved with Yaz. It was an argument she had with herself almost daily. Back and forth.

But Yaz had burst through her walls. Getting to act like Yaz's lover, listening to her friend's trauma, realising she was being let in by someone really special, had certainly shaken her foundations. And then Yaz had kissed her. There was no going back now. Reaching out, she pulled Yaz's hand into hers. It was immediately reciprocated. It had been so long since she had allowed this for herself. Happiness.

'It certainly has,' she replied, looking softly at her friend. Yaz caught her gaze and smiled back, before turning her head back to the sunrise.

'Doctor?' Yaz asked, tentative this time. She was a bit nervous to ask the question, but she wanted to discuss it.

'Yup?'

'When I walked in on you and Danny arguing, you looked really angry. What were you fighting about?' Beside her, she felt The Doctor bristle at the mention of Danny. Yaz hated to bring it up, but she wanted to know. The Doctor let out a long sigh, before squeezing Yaz's hand.

'He came up and pestered me about talking to you. At that point, all I knew was that he was your ex and that he'd hurt you, so I just wanted him to go away.' She paused, trying to keep her irritation at bay, for Yaz's sake. 'As I was acting as your partner, I told him to back off. Would have done that regardless. He couldn't understand why you were with a woman.'

'Well, I suppose… I'd never told him I was interested in both, so he just assumed.'

'That figures. I thought he was going to back off, but then seemed to have some sort of epiphany and decided he wanted you back.'

'And he said this all to you? Knowing full well that you were with me?' The Doctor nodded, although her irritation waned slightly. Her heart did a double take when she realised that Yaz hadn't slipped in anything about the fake dating. Yaz, meanwhile, shook her head in disbelief.

'What an idiot!' She laughed. The Doctor couldn't help but feel smug. But at the same, there was a knot of anxiety at the edge of her mind.

'Does that knowledge change anything now?' The Doctor asked softly, looking at Yaz directly. Yaz could see the anxiety and dread in The Doctor's eyes. She smiled at her friend, slightly amused that The Doctor would ever worry about any kind of competition.

'No, of course not. I told you, I'm not in love with him anymore. After everything that happened, I could never go back to that.' The Doctor let out a sigh of relief.

'Okay, good. That's good. Because, y'know, you're too good for him anyway.' Yaz surveyed The Doctor, and could see there was still something lingering underneath the anxiety. What was it? Yaz knew The Doctor was angry at Danny, but this was slightly different. On a similar scale to anger, but more insidious. She'd seen it before, flashes of it during their previous adventures. That look usually appeared when 'the assumption' about Yaz and Ryan being a couple came up, or when anyone would bring up Yaz's crushes, or… then it clicked.

'Doctor, were you jealous?!' She asked in surprise, her voice increasing in pitch. That was the closest Yaz had got to addressing and actually requesting confirmation of The Doctor's feelings for her. The Doctor was clearly taken aback by the question, and was quick to get defensive.

'Jealous? Me? Time Lords don't get jealous. What even is jealousy? I believe there is a planet out there that uses jealousy as currency, although thinking about that I can't see how that would really work…'

'Doctor, stop deflecting.'

'I'm not!' She whined, like a small child. Yaz stifled a laugh. 'Why would I be jealous? Just because he's your ex and you two have a shared past. I'm not threatened, no. No way. No. Even the notion…' She was cut off by Yaz's lips on hers. The Doctor was taken by surprise, frozen in place. Yaz smiled and pulled away, leaving The Doctor speechless.

'Okay, you're not jealous,' she winked. The Doctor opened her mouth to respond when Yaz continued. 'But, say you were, y'know, jealous. I just want you to know that you have nothing to worry about. Absolutely nothing. Okay?' Yaz scooted up closer to her friend, their whole bodies aligned. She wrapped her arm around The Doctor's waist, pulling the alien closer to her. She pressed a kiss to The Doctor's temple. 'You've given me so much in our friendship, more than he ever did when I was with him. I'm so grateful for you in my life.'

The Doctor melted into her side, letting out a sigh of relief. Yaz waited for her to respond, but The Doctor remained silent. Yaz guessed she would communicate in her own time.

They continued to stare out to the rising sun, which was getting higher by the minute. Finally, The Doctor responded.

'Maybe I was jealous,' she finally admitted. Yaz blinked in surprise. She hadn't thought that The Doctor would ever admit it. She also couldn't comprehend the fact that The Doctor was jealous… over her! 'And not just last night. I think… jealousy might have flared up a few times.'

'I can't believe you get jealous. You, of all people,' Yaz exclaimed. The Doctor looked up at her, something new flashing in her eyes. Possessiveness.

'Well, you have a lot of admirers. Can't help it if I don't like it…'

Yaz guffawed. What was The Doctor talking about?

'I don't have a lot of admirers.'

'Believe me Yaz, you've had plenty on our adventures together. You might not see it, but I do. There are a lot of people in the universe who have wanted you, Yaz.' Yaz was so confused. She had never seen it herself. The Doctor smiled softly. 'I can't blame them really.'

'What about the people who have been interested in you? You're the one with plenty admirers!' Yaz stated, knowing that was a fact. She herself had been jealous when anyone ever hit on The Doctor. But to her relief, The Doctor had always blocked their advances. The Doctor pulled a face.

'Nah. If they have, I've not been interested. I must admit, I did go through a phase of… flirtatious behaviour, I suppose. My tenth and eleventh selves had a fair bit of fun, but since then…' She tailed off, realising Yaz may not want to hear about her past lovers. That wasn't fair. She glanced over at her friend, but instead of finding her upset, she looked mildly amused.

'You? Flirty?'

'I can be flirty!'

'Well, now I know you can be.' Yaz smirked. 'When you say your past selves, do you mean like the white haired Scotsman you mentioned?' The Doctor nodded.

'I've had a lot of faces, Yaz.'

'Could I see them? Pictures, I mean?' The Doctor looked surprised, but not displeased.

'Really?'

'Yeah! I want to know more about you.'

The Doctor smiled fondly at her young companion. 'Yeah, sure. Hold on.' She reached into her pockets, rummaging around for something. Finally, she was successful. She pulled out a tattered wallet. It clearly hadn't seen the light out of day in a while. She held it up, letting it fall open. It was a photo wallet that expanded out, as multiple photos fluttered down. Yaz could see a blur of colour as The Doctor waved it.

Yaz counted the photos. 12.

'You've had 12 faces?' She asked, starting to take them in. The Doctor balanced them out in a line, crossing her and Yaz's lap.

'Well, technically I've had 14. I've not updated it since my last regeneration, and there were a couple of faces that never had photos taken, so… a bit wibbly wobbly, but these are most of my faces.'

Yaz inspected them closely. All male. Each one so different, but still The Doctor. One with white hair. One with a recorder. One in a yellow car. One with the longest scarf Yaz had ever seen. One with a stick of celery. One in brightly coloured clothes. One with a fun umbrella and hat. One with curly hair. One with a leather jacket. One in a brown suit. One adorned bow ties. And the last one. The white haired Scotsman.

'Damn, those are some angry eyebrows!' She commented. The Doctor laughed.

'Yes, he was particularly Scottish.'

'So your accent changes too?'

'Everything changes. Well, you can see that.' The Doctor gestured to herself. Yaz looked back down at the pictures. Her fingers traced over their features, allowing herself to drink in The Doctor. All of them.

'That's incredible,' Yaz whispered in awe. All these men had lived long lives, but didn't exist anymore. But they did, because they were all in her friend.

'Yeah, regeneration has got me out of a few scrapes,' The Doctor said lightly. Yaz could tell the lightness was covering things that were a lot deeper, obviously painful. Yaz knew that regeneration, whilst lifesaving, meant that a version of The Doctor died. Yaz glanced at each of them again.

'Is there a particular face you loved being the most?' She asked. The Doctor pondered, genuinely surprised at the question.

'I don't know, actually. There were some that faced harder times than other.' She pointed to her ninth face. 'He had to deal with being the only survivor of the time war. He lived his whole regeneration believing he'd killed his own people.' She paused, then pointed to her tenth self. 'He also had to, but by the time you get to my eleventh face,' she paused, pointing at bow-tie fan, 'He discovered a way to make it so that the end of the time war never happened. So, in a way, he was the one who absolved me of my guilt.'

The Doctor's eyes became impossibly old. Yaz couldn't even begin to comprehend the pain her friend must have endured. She swallowed back some tears, determined to not cry anymore that night. She reached out her hand and took The Doctor's in hers.

'You really are the best person I've ever met.' She spoke softly, trying to convey all her feelings and comfort through those words. The Doctor glanced at her, and squeezed in response.

'Thank you, Yaz,' she whispered. She leant in and dropped a kiss to Yaz's cheek, letting her lips linger there. Yaz's breath caught in her throat. To distract herself, and The Doctor, she looked back down at the pictures. There was one in particular that piqued her interest. She pulled the picture closer to her, nodding approvingly.

'You used to be quite hot,' Yaz quipped, pointing to the picture. It was her tenth face. The Doctor rolled her eyes.

'Like I said, my tenth and eleventh faces were my flirtatious days… hang on…' She paused. 'Used to be?!' The Doctor pulled the picture towards her, inspecting it closer. She opened her mouth at the injustice. Yaz couldn't stop herself laughing. The Doctor thrust it down, pouting.

'Doctor, I'm kidding. Obviously you're still hot.' She paused, glancing at The Doctor, who perked up slightly, preening. Yaz looked back down at the pictures, still winding her friend up. 'But your tenth face, damn, he's fine…' The Doctor pulled the wallet out of both their laps and started winding up the photos.

'I think that's enough history lessons for today,' she huffed She stuffed them back into her pocket. Yaz laughed.

'Doctor, you're seriously not jealous of yourself, are you?'

'No, of course not…'

'Come here, you ridiculous alien.' Yaz pulled The Doctor closer to her, finding her lips. Even The Doctor couldn't argue with a kiss from Yaz. The Doctor responded, cupping Yaz's cheek and drawing her in. Yaz wrapped her arms around The Doctor, her heart beating fast and happy beneath her chest. After a few long moments, they reluctantly let go of each other. They shared a small, shy smile.

'I don't think I'll ever get used to that,' Yaz murmured. The Doctor grinned.

'Oh Yaz, this is just the beginning.' She looked across at the sunrise, taking its beauty one more time before daybreak. 'But right now, I think you, my human companion, need to go and get some sleep.'

'I'm fine!' Yaz really homed in her point when a yawn broke out unexpectedly. She caught The Doctor's eye, who let out a low laugh. 'Okay, maybe I should go take a kip.' She needed to sleep, but didn't want to leave The Doctor behind. They were closer than they ever had been. 'Do you want to come with me?'

The two women sized each other. The Doctor would love to lay in bed with Yaz, snuggle up to her, and just be with her. But a lot had happened in the past few hours, and she knew that they both needed some space to wrap their heads around it all. Reluctantly, she shook her head.

'You go get some sleep, Yaz. I'm a super fidget, and I don't need sleep like you do.' She paused, as Yaz's shoulders slumped in disappointment. 'I will another time, though,' she added, which had the opposite effect. Yaz beamed at her.

'Okay, good plan.' She stood up to go, but The Doctor pulled her into a hug, stopping her from moving. She instantly gave in and held her friend. The Doctor held her tightly, securely. Just like so many nights on the TARDIS.

But this time it was different. This time, Yaz didn't have to hold back. She clung to The Doctor, taking in her scent, the feel of her hair against her cheeks, the solid beats of her hearts. They held each other for a couple of minutes, before reluctantly, Yaz pulled out of the hug and stood up. The Doctor let her arms fall to her sides, suddenly bereft.

'Catch you later, Doctor.'

'Sweet dreams, Yasmin Khan.'

With one last look at The Doctor, grinning, she turned away, and began the ascent back to her flat. The night was done, but their relationship had just begun. Yaz couldn't stop smiling as she fumbled with her keys. One last look over the balcony, and she could see The Doctor, still sat on the bench, looking out to the city. She wondered if she felt as euphoric as she did. Grinning, she turned away and entered her flat, ready for good dreams.

The Doctor stayed where she was. She couldn't help but smile. Happiness washed over her as the rising sun glided over the city. In that moment, she wasn't thinking about the dark times that may be ahead for them. She was remembering the way Yaz felt against her, her smile, the way she looked under a sunrise. She let herself embrace the love that she'd been repressing, finally setting it free and allowing it to consume her. Peace overtook her.

Which made it so easy for her attacker. Her defences were down, and before she could even comprehend what was happening, everything went black.
