(Y/n) lagged behind as the Doctor sprinted towards the hanger. She couldn't believe what she had done. What happened back there? The anger that had consumed her felt unnatural. She went inside and came to stand with Ada and Noor. The mark on her left arm blazed and her eyes made contact with the timelord that had nearly killed her. The Master stared back at her, illuminated by the Kasaavin like an angel. Regret was clear in his eyes as they trailed to her neck and then to the floor. The Doctor's gaze remained fixed on the Master as she revealed to the Kasaavin his plan by replaying his confession. (Y/n) felt sick at the hostility that was building between them. The Kasaavin moved to attack the Master and (Y/n) felt herself running towards him, but was hold back.

"Please." She begged the Doctor as she fought against her grip. "Help him. Please. I know all the things he has done is wrong, but haven't we all done bad things?" (Y/n) saw the inner battle going on behind the Doctor's eyes. Her shoulders sagged in defeat as she activated her sonic, exiling the Kasaavin back to their dimension. The Doctor's grip loosened around her arm and (Y/n) reluctantly pulled away. She gasped as Yaz launched herself into her arms.

"Thank God you're okay." Define okay, she thought bitterly to herself.

"Doc? What's going on and are we being replaced?" Graham asked as he looked at Ada and Noor.

"What? No! This is Ada and Noor. They've been helping me."

"Hey, how did you do that whole thing with the plane?" Ryan asked.

"The plane? Oh, I forgot. I'll be right back. You -" She glared at the Master. "Stay here until I get back. Come on you two." She waved at Ada and Noor to her follow her as she ran from the hanger. The women of time sent smiles and small waves in (Y/n)'s direction before running after the Doctor.

"Has she seriously gone and left us with this nutter?" Graham gave the Master a cautious glance.

The Master growled at him. "I can hear you - you know?"

"You were meant to. You tried to kill us on that plane and you kidnapped (Y/n)!"

"Graham." (Y/n) spoke up. "It's alright. He won't try anything." The Master eyes snapped to hers with shock not expecting her to stand up for him; not after what he did.

"(Y/n)? What's going on with your arms? They're glowing." Yaz gasped as she stared at her friend's skin. (Y/n)'s eyes widened as she realised in her panic to run after the Doctor, she had forgotten to pull down the sleeves of her shirt. Her marks were display for all to see. She suddenly felt uncomfortable with all eyes on her as she yanked down her shirt sleeves. "It's nothing."

"Are - are those soulmate marks?" The gears in Yaz's brain began to turn as she looked at her friend and then to the manic timelord. "Is he? Are you soulmates?"

"And what if we are?" (Y/n) spat in defence as she folded her arms across her chest. She didn't want them to find out, not like this, not when she didn't have all the answers, not when she was scared out her mind at the possibility that the beings she was tethered to were slowly eating away at her; gnawing away at her soul until there was nothing left.

"But doesn't explain why you have two."

"Yaz, drop it, please."

"The Doctor..." Yaz said in realisation. "The Doctor is your soulmate too, isn't she?"

Graham and Ryan's mouths hung open at the revelation. They had heard of people having a soulmark, but not two.

(Y/n) wanted to curl into a ball and disappear. It was all coming back. The bullying, the abuse. Why her? She wanted it all to stop. She fought hard to keep her emotion in check. She would not let them see her cry. Warmth enveloped her and a feeling of peace swept over her mind silencing the horrors of her past. Her cries finally broke free as she sunk into her soulmate's embrace.

"If you all want to remain breathing and in one piece, I suggest you stop looking at her like she's some freak show." The Master spat as he kept (Y/n) in his arms.

"What did I miss?" The Doctor questioned as she walked back into the hanger alone. She took in the guilty and ashamed expression of her fam before settling her gaze on the Master and (Y/n) who was shaking in his arms.

"They know." He told her as he pressed a kiss to (Y/n)'s forehead.

—

Ryan, Graham and Yaz had many questions for the trio, but understood when the Doctor said that she was going to drop them off home for a while. The console room was silent as the three soulmates tried to come to terms with the fact that they were finally all alone together. (Y/n) had taken a seat on one of the steps at the back of the Tardis and hugged her legs close to her chest. Her forehead rested against her legs as she tried to stop her head from spinning. The channel between them to seemed to have opened again as a whirlwind of emotion raced through all of them to the point where (Y/n) didn't know if the emotions she was feeling were her own. The Master couldn't stand the silence anymore.

"So, what happens now? We're all here in the same room, finally. The one I have been dreaming about since we were children, but why is it I can feel nothing but disappoint and contempt from you?"

"You know why." The Doctor replied flatly. The Master's gaze met to (Y/n)'s before he looked to the floor in shame. "I fixed it."

"That doesn't excuse the fact that it happened. You could have killed her! If hadn't given her the energy to throw you off, she would have died."

The Master began to pace as he fought to keep his anger under control. He felt the urges he tried so hard to supress resurface. The pounding in his mind thudded against his resolve. "Don't you dare take the moral high ground with me! It was you who made her feel ignored, invisible, unloved! This is what you're good at though, isn't it, Doctor? Pushing people away!" The Doctor grit her teeth as pain pulsed through her mark.

"I did it to protect her!"

"Well, you did one hell of a job! She's dying because of us! The bond between us is tearing her apart!" (Y/n) flinched at the ferocity of his words. Her soulmarks roared with the Doctor's pain and the Master's anger. Her vision blurred as her head throbbed in agony. If she was not sitting down, she was certain she would have collapsed.

Both soulmates now stood chest to chest with each other. Breathing heavily. Both too stubborn to back down, too proud to admit how the hum bond between them made them feel. Oblivious to how this was effecting (Y/n).

"You think I don't know that? It's the reason why I distanced myself from her in the first place. I knew from the moment I met her it could never happen. I knew her human mind and body would never accept the bond. You know what I should have done? I should have left her on earth the minute I knew who she was, but I was selfish."

"That makes two of us."

"Guys?" (Y/n)'s weakened voice caught their attention. The both of them reacted on instinct as they ran forward and took a hold of her shoulders before she could collapse to the floor.

"Finally noticed that I'm still here, huh? No complaints from me, though. You two getting chest to chest with each other was hot." She had no idea where that had come from and blamed it on her delirious state. The Doctor scanned her with the sonic and frowned at the readings as her eyes glazed over. A wave of nausea hit (Y/n) as her head lulled to the side coming to rest on the Master's shoulder. Her arms felt like led, but forced them to move in attempt to bring her soulmates closer. The Doctor took a hold of her hand and kissed it before holding it to her chest. The Master brushed his hands through her hair as she drifted in and out of consciousness.

There was no way he going to let her die; not when he finally had her in his arms with the Doctor by his side. The Universe was against them, but when did something like that ever stop the Master from getting what he wanted?
