Going back over her life was something Danni did like to do on occasion. Her memories were incredibly precious to her. But, usually, it was in a much more relaxed setting. She could sit down with a cup of tea, pop a movie on and watch it while reminiscing.

Going over and over her memories trying to pinpoint the time someone was trying to alter her husband's timeline and inadvertently erasing her from time wasn't quite as pleasant. She wanted to be able to enjoy the memories, not have to dismiss them for whatever reason the Doctor, River or herself came up with.

"After that you weren't there for four years," the Doctor told her factually. "I don't think we saw River during that time."

Danni frowned to herself. "Four years?" she repeated. "I don't remember it being that long."

He shot her a look from his seat on the floor. "Trust me, it was that long," he retorted. "Did we go after that?"

Danni shrugged, chucking the pad of paper on the floor. "I have no idea," she snapped in frustration. "It's been hundreds of years, and my life wasn't in order to begin with! How the hell am I supposed to remember it?"

The Doctor quickly climbed up off the floor, walking over to his wife and held his hand out to her. She looked at him with a face full of annoyance, but then she took it and he helped her off the chair. He wrapped his arms around her.

"Getting upset is not going to help," he pointed out. "Maybe you should take a break? Have one of those showers you love so much while River continues to sort through the photos?"

River raised her head, pulling a face behind his back. "Sure, leave me to do the dogs work," she declared loudly.

Danni shook her head. "What? Go have a shower so I can just be ripped out of time all by myself?" she countered. "If I'm going to be erased from history..."

"You're not going to be erased!" the Doctor protested.

"If," she reiterated, "then I don't want the last thing I see to be a wet, tiled wall." She sighed, breaking out of his grasp. "I don't want..."

He caught her hands in his. "I understand," he promised. "I do. And you're not going to be erased. You've got both me and your mother on your side. We'll figure out what, exactly, whoever is fiddling with my time line is trying to achieve and we will sort it."

She nodded, taking a deep breath to try and calm herself down. "I'm going to..." she nodded to the ground. "Maybe some of those will jog my memory better."

He placed a hand on the small of her back, encouragingly nudging her over to River. "I'm going to tinker with the psychic interface some more," he replied. "See if we can home in on any discrepancies."

She sat across from River, looking at all the little piles of photographs she had made. Each one for a different companion, with Amy and Rory's much more organised just because she'd heard the stories more than enough. Despite her annoyed attitude, she really was putting her all into helping them at least narrow down a time.

"Thank you," Danni told her sincerely and the bushy-haired woman looked up in surprise. "You really didn't need to do this, but I'm glad you're here."

"Of course I did," River retorted, looking at the small pile in her hand and separating them accordingly. She wasn't sure if sorting the photos out would really be any help, but as she'd offered all the memories she had – which apparently had not been as much as they'd all hoped – then this was all she could do. "Who else was going to help? Your father?"

"Hey," Danni scolded, picking up some photos herself. "Jack has been very helpful so far. The Face of Boe was the one who sent us to you in the first place."

"Of course he was. Sending you to me when he could be helping you himself."

"He's a head in a jar," Danni retorted. "What could he do, exactly?"

"He can feel changes in time," River pointed out. "It's one of his… I dunno, super power or something, you told me. Surely he could pinpoint where this was happening."

"Leave Jack alone," Danni demanded, although she did have a point. "He said he wasn't sure what was happening. He said you could help."

"And I am helping," River replied, purposefully placing a picture of Martha on a pile of many. "I think he just got too used to outsourcing."

Danni couldn't help but giggle at that. "He is a real business man," she agreed. "Well, business head, I guess. They keep trying to get us to sign non disclosure agreements."

River snorted. "That's their own fault," she replied. "Have you ever signed one?"

"Of course not," Danni replied, acting shocked that she would even think it. "I think he just does it to the newbies. Not everyone asks."

The Doctor smiled to himself as he listened to his wife natter on with her mother. Truthfully there wasn't much else that he could do with the interface. Everytime he felt he had a hold of the time and place their culprit was in, it would slip away. They seemed to be all over the spot, he didn't understand it.

He'd just wanted to relax her. If he couldn't save her – a thought which brought a lump to his throat and an almost overwhelming urge to hold her close – then he didn't want her being erased while being worried. He wanted her happy. He wanted to remember her happy.

And if that meant a bit of banter between her and River, well, he could handle that.

Danni frowned as she reached over, placing a picture of Martha with the rest of the pictures of Martha. They weren't coming across any other discrepancies with the pictures beyond the missing Rose ones. Martha, Donna, Amy and Rory, Clara, they all seemed to be in place. All in all the Doctor's timeline seemed pretty much in tact. So maybe they were looking at the wrong thing. Maybe the companions weren't the way to go.

River looked to her daughter, who seemingly had frozen in thought, her hand hovering as she forgot the task she had begun. "Danni?" she asked and the Doctor looked over at her, his own brows furrowing. "What is it?"

"Have you been separating the pictures of you from here?" Danni asked in return and River nodded, motioning to a pile by her side.

"I was going to steal a couple for myself," she admitted boldly. "Why?"

"What about Jack?"

"What about him?" River shot back.

"His pictures. Where are his pictures?" she clarified and River shrugged.

"I dunno," she replied. "I didn't think he was particularly important."

Of course she didn't. Danni immediately placed the picture she had in hand onto the pile before using both of her hands to spread it out wide, scattering the photos everywhere.

"What are you doing?" River exclaimed as Danni messed up all her work. She wasn't too bothered about the photos themselves, but she had just spent ages sorting them out.

"Where's Jack?" Danni counted. "Jack should be in here. Where is he?" She moved onto the Amy and Rory pile, spreading them out and flicking them behind her.

"Who cares?" River countered and Danni stopped her search to look at her.

"Look at them," she replied. "The only thing that has changed in all of them is the person taking them. I'm the only thing that changes… I mean, look at..." She picked up a picture of Martha. It was one of her in snow. "Look at this. This is when we went skating, right at the start when I was still getting used to jumping about. This was a story that I heard about in my old universe, when I wasn't there. And… And this one," she picked up one of Donna. "This is one Donna took for me, when I wasn't there. This would have happened regardless. Apart from me taking the picture, these events will still have happened."

The Doctor walked over, leaning against the side of the console as she turned to River. "When I disappeared, you remembered me, didn't you?" she asked her mother, who nodded. "You have memories of me in place, like I'd never left, except in one place."

"At my graduation," River confirmed before her brows furrowed. "What are you suggesting, exactly?"

"We've been looking all over the Doctor's time line trying to find what is wrong," Danni explained. "But nothing is wrong." She looked up at her husband. "Your time line is fine. Everything that was supposed to happen is still happening. Anything that changes with me not being there is a by product, not causation."

"You don't think they're messing around with my time line?" he asked her and she nodded. "But it's directly affecting my life. You're disappearing, which means that I never introduce you to anyone. You're not there to change the events because something in my time line is changing."

"Where's Jack?" she countered. "He should be somewhere. There aren't any pictures of him."

"There wasn't any pictures of Rose," he pointed out. "It just means that the changes are becoming more permanent and we have to fix it."

River shook her head. "No, there's no pictures of Rose because she wasn't there to take them. But she was there for these," she explained, going through her own pile of photos quickly.

"The thing that changes in these pictures isn't the time or the place, it's the people missing," Danni told her husband. "I'm behind the camera, but Jack's missing completely. What if it's Jack? What if he's sent us to River because he can't interfere in his own time line?"

"If he's being killed before you were born then that would explain your disappearences," the Doctor said. "The longer it takes for him to get back on track, the longer you're gone for. But for what purpose? There's better ways of getting my attention."

She looked down at the pictures that were scattered across the floor. "Theta," she started slowly. "They're not trying to rewrite your timeline." She picked up a picture of Amy and Rory. Her grandparents. Her father. Her mother's graduation. She looked back up at her husband. "It's me," she breathed. "They're trying to erase me."

~0~0~0~

It was with a lot of pain and a deep breath that Jack Harkness came back to life. Every time it happened it was agony, but every time he got up and carried on because if he'd been killed, it was normally for a reason. He'd learnt long ago that he may not always come back completely orientated so he knew that his first task was to get the hell out of any place where he'd woken up in.

This time, though, there was something rather large driving him to get up and go. Whoever had put him in the room he'd woken up in was very apologetic for killing him, but that it was for 'the greater good'. To hurt his daughter. To stop her from being born. By killing him they'd stop her from being conceived and she'd flit out of existence. He couldn't let that happen.

He sat up on the bed they'd laid him out on and was rather pleased to find that they'd actually brought him into a hospital. The times between his resurrections could vary so he really had no idea how long he'd been out, but it was long enough for them to think that they'd actually managed to keep him dead.

He chuckled to himself and hopped off the bed, grabbing the plastic bag of his belongings from the metal table he was by. They'd taken his gun, unfortunately, but luckily he'd not been wearing his manipulator so it hadn't fallen into the wrong hands.

He slipped on his jacket and moved to the door, taking his time to check the coast was clear before heading out and hopefully away. Chances were that the people who wanted Danni gone were already aware that their plan didn't work. He needed to get home and contact her, and fast.

There was a gunshot and he turned around just in time for it to enter through his forehead, splattering blood and flesh on the wall behind him. Jack Harkness dropped to the floor, dead once again.
