Sacrifices

The Doctor, Jack and Holly crouched behind the TARDIS, watching the scene before them unfold. They'd travelled back to the point just before the Opals shot lightning bolts of energy at the Doctor.

The Past Doctor had just realised that Rose was being possessed and discovered that he was surrounded. Present Opal stood just in front of the TARDIS, with Past Opal to the left of her and Opal/Rose was some 5 metres away in front of them, engrossed in her conversation with the Past Doctor.
As the Opals began to argue amongst themselves, Holly slipped on her LEP helmet and started up her wings. She cast a questioning glance at the Doctor, who nodded, and she shielded and hovered half a foot or so off the ground.
Holly flew silently and slowly towards Present Opal, whose back was to her. She hovered about a hand's breadth behind her and watched as all three Opal's cackled and then turned towards Past Foaly who came cantering out of the house. Holly swallowed as Opal/Rose turned back to the Past Doctor and spoke.
"Let's see you heal this, Doctor,"
There were only a few seconds left before Holly had to act. She reached out a hand as Present Opal cackled and as she prepared to fire her lightning bolts of energy. Holly pushed Present Opal's right shoulder slightly, so that Opal swivelled 90 degrees to the right and fired her lightning bolts in the wrong direction. Not towards the Past Doctor at all. But towards Past Opal.

Past Opal didn't even notice the lightning coming at her. Her entire being was focused on shooting her laser gun at the Past Doctor who was stumbling backwards in an effort to get away from the lightning. All of a sudden she felt cold for a second and shivered, before the cold red lightning stopped her heart.

Present Opal just stared as Past Opal collapsed. Opal/Rose hadn't noticed either of them, and she was screaming and shouting because the Past Doctor had disappeared. Present Opal felt odd. Like she was becoming transparent. Like she was separating, being ripped apart, atom by atom. Which in fact, she was. For her past self had died, so she herself would die too. She had only just realised this before her atoms tore apart completely and drifted away on the breeze.

Holly, Jack and the Doctor ran into the TARDIS, all the while watching Opal/Rose firing lightning bolts around her at the ground, raising clouds of dirt. Once they were safely inside and the door was locked, they let out a breath that they hadn't realised they had been holding.
Jack looked towards the Doctor and frowned in thought.
"Wait a minute, Doctor; you've just created a paradox. Won't it rip the universe apart?" he asked the Time Lord.
The Doctor grinned.
"Normally, yes, but I haven't managed to fully change the TARDIS back from the paradox machine she was, when the Master ruled her. As long as the paradox isn't too large, it'll be fine."
"But then shouldn't Present Opal have stayed alive, because the TARDIS is still a paradox machine?"
The Doctor shook his head.
"Too large a paradox, she can't handle it now. She could have when she was still completely a paradox machine, but now? No, she's still only slightly a paradox machine. A life and death paradox is too large."
Jack just nodded, pretending he understood what the Doctor was rambling about.
Holly just stayed silent, still shaken over the events that had just happened. Two Opals down, one to go. But this Opal was smarter, tricker than the other two. And plus she had Rose. So the Doctor was almost completely in her power. She had no idea what the Doctor's plan was, what he was willing to do, to get rid of Parallel Opal. He hadn't told anyone his plan. They weren't even sure if he had one. But she trusted him, even though he seemed indecisive about whether to save the universe or to save Rose. But she was sure that he knew that he couldn't save both.

The Doctor was thinking about his plan. It was a simple plan, in theory. It wasn't even very hard. It wasn't hard physically, but it was mentally. For anyone except the Doctor, it would have been easier. A lot easier. But he couldn't put anyone else in that danger. It had to be him. Whether he liked it or not. He didn't. Not one bit.

The Doctor pushed buttons and pulled levers on the console of the TARDIS. And they all held on as the TARDIS shook and jerked her way back to Cardiff where Foaly, Mulch and Artemis were waiting. Suddenly the TARDIS stopped roughly, and Holly fell onto the grating. Picking herself up, she followed the other two out of the doors.

The Doctor left Jack, Holly, Foaly, Mulch and Artemis in the TARDIS which was again standing in the present time on the grass at Fowl Manor. This was something he had to do alone.

He swallowed and slipped a hand into his coat pocket, his hand groping around and then finding the small, smooth metal object. He dragged a hand over his face and bit his lip. Wishing there was some other way to save the universe. But there wasn't. It wasn't going to be easy.
He tried to look determined and confident as he strode towards Opal/Rose who was clutching Rose's TARDIS key in her hand and looking outraged.
"You!" she spat at him.
"You changed the past, didn't you?" She continued.
"I felt my memories being changed, altered. How did you go back and change what happened? I had everything you had. I had Rose. And I had your TARDIS. You couldn't have gone back."
"No," he said, "You don't have everything I have," he allowed himself a brief smile; "I have something you could never have, that you have never had. I have friends. Friends willing to help me. Help me get Rose back."
"But you can't get her back!" Opal/Rose hissed.
"I am in control of her. Her mind and thoughts are just tucked away in a corner. And you're cornered too, Doctor. There is only one way to save the universe, to get out of this, and both you and I know you're not going to take it, not going to risk it."
"Oh won't I?" asked the Doctor, before he lunged forward, drawing the metal object from his pocket as he did so, and lodged the dagger in Rose's chest.

Opal/Rose just stood there, mouth open, shocked, for a moment, blood already drenching her clothes.
"You didn't!" she whispered.
"How could you," she continued, shaking her head, "I never thought you were so heartsless, Doctor. How wrong I was to underestimate you. I thought you had feelings. I thought you cared so much for Rose that you wouldn't be able to even think about sacrificing her to save the universe, to stop me."
She gritted her teeth against the pain and grinned.
"But you haven't stopped me!"
And with that, the Doctor watched as Opal/Rose fell to her knees and then red swirling mist poured out of Rose's mouth, and the mist that was Opal's soul floated upwards until it was above the Doctor's head. It watched Rose's eyes un focus, watched Rose slump to the ground, the dagger still sticking out of her chest. And it seemed to laugh as Rose bled to death.
