Part Three

They landed silently, the TARDIS cloaked, in the data core of CAL and the Doctor turned on the scanner, allowing himself and Imogen to watch as River bent over the body of Anita. She whispered her name sadly, caressing Anita's helmet.

"I'm sorry, she's been dead a while now; I told you to go." The Doctor's past self said as he looked at a computer screen.

"Lux can manage without me," River said, "but you can't." And she walked to him, punching him in the face so that he fell to the floor unconscious.

"That really hurt, you know."

River spun around and stared as the current Doctor smiled sadly at her, rubbing his cheek in memory of the sharp pain her punch had caused. Inside the TARDIS Imogen, having not realised the Doctor had left until he appeared on the scanner, jumped.

The Doctor pulled a pair of handcuffs from his pocket, "Want to borrow these?"

River grabbed them without question and handcuffed his unconscious past self to a pillar, once that was done she turned and slapped the Doctor across the face. "You are insufferable!" she snapped at him,

"Ow, River," The Doctor rubbed his cheek, "That hurt,"

She glared at him, "It better have," she glowered, "you could have warned me, you bloody idiot, you could have told me that the next time I called I'd be getting him! I have never been so…" she had tears in her eyes, of anger or sadness, the Doctor wasn't sure, "The way you looked at me," she wiped her eyes furiously, "I wasn't prepared for that."

The Doctor stepped forward, and pulled River too him, kissing her gently, tenderly, begging her for forgiveness. River moaned and wrapped her arms around his neck, kissing him back. When she pulled away her face was much calmer, the anger melted away and she smiled, somewhat sadly. "You taste like me." She murmured, "Have you just come from Darillium?"

"Not quite."

She kissed him again then rested her head on his shoulder, "You're not going to stop me from doing this you know."

"I wouldn't dare."

"Then why are you here?" she whispered,

The Doctor sighed sadly and closed his eyes, "To say goodbye."

She looked up at him, "I'm sorry, my love,"

"I know," He murmured, "You don't need to tell me." He cupped her cheek and pressed a kiss to her forehead, "Tell her," And Imogen stepped into view.

River stared, the girl that stood before her was a lot different to the Imogen she knew, but yet, she could feel, in her hearts and her mind, she could tell that this was her daughter. "Oh my baby," she whispered, and she rushed forward pulling her daughter into a hug, "My darling, I am so sorry."

Imogen nodded into her mother's shoulder, crying, and pulled back to wipe away her tears, "I know, Mum," She sniffed, "I'm sorry too." And she pulled out a black gun and quickly shot them both.

River woke up and found herself sitting next to the hand cuffed Doctor, she looked around. There was no sign of Imogen, the TARDIS or her Doctor. Quickly she scrambled up and started to wire herself into the computer, forcing herself not to think of her daughter or husband, and to focus only on the task at hand. The Doctor woke and struggled, fighting with her to take her place; she cried and told him, "There's nothing you can do."

"You can let me do this!" He yelled at her,

She shook her head, tears spilling down her cheeks, "If you die here it'll mean I've never met you,"

"Time can be rewritten,"

"Not those times; not one line. Don't you dare."

And then she was lifting the circuits she'd built to her head and listening to the computer count down as this incredibly young Doctor cried for her, a stranger he'd met only today but already knew would someday be his wife.

"Shush now," she whispered with a sad smile, "Spoilers." And she brought the two main wires together and felt a surge of electrical currents run through her, her whole body flying back with the force, and she died.

tbc!
