"Doctor," Aries grabbed the Time Lords sleeve when they entered the outer room of the church, stopping him from walking off and he turned to her, "What's going on? What are you doing here?" she questioned, trying out work out why he was here.

The Doctor glanced around before leading her over to a window as he tried to figure out how to tell her what had happened. He was still trying to work out what Aries' was doing there, just having dropped her off...well, wherever the TARDIS had decided to take her, but he had rather hoped that after what Rose had done, his Nesdra would have been safe. "Something happened," he said, and Aries just raised an eyebrow.

"I can clearly see that," she stated, letting his arm go with a frown and stepped back when she suddenly felt the urge to grab his hand at the sight of his troubled expression. "I want to know what has happened, because I have my-"

"Eris," Pete Tyler's urgent voice cut her off and she turned to the man, missing the Doctor's eyebrows furrow in confusion once again. "There's smoke coming up from the city but no sirens," the man continued as he reached them, "I, I don't think it's just us, I think there things are all over the place. Maybe the whole world."

"Look, Pete. This isn't the best time," Aries told the man as she turned back to the Doctor, only to see the Time Lord looking out the window with an expression of dismay. Frowning, she followed his gaze and her eyebrows raised in alarm when a beige car appeared out of thin air, its tyres screeching. It turned a corner and the terrified driver threw a hand over his face as it disappeared.

"Was that a car?" Pete questioned when the same thing happened again.

"It's not important," the Doctor said after a moment and Aries glanced at him, finding that she didn't believe him. "Don't worry about it," he told Pete as he grabbed Aries hand and they moved away from the man.

When they were far enough away, Aries pulled her hand from the Doctor's. "I don't know what's going on, Doctor, but I don't believe for a moment that a car that reappears and disappears in unimportant," she told him in a harsh whisper, "Now, tell me. What is going on?"

The Doctor's shoulders fell slightly, knowing that Aries wasn't to stop until she figured out what had happened. He just hoped she wasn't going to be too angry with him. The Time Lord couldn't help but also feel a nagging familiarity with the name that the other humans kept on calling her. He just couldn't remember why.

"Rose," the Doctor sighed, "I did something I shouldn't have and it went wrong," he admitted, knowing he was just as in the wrong, if not more than his blonde companion.

Aries glanced towards the door that led to the main room of the church, watching Pete leave and caught a glimpse of the older blonde. Her eyes widened when she realised something, "You shouldn't even be here," she hissed turning back to the Doctor, "Rose should not be here. What were you thinking, bringing her to a place where there was already a version of herself here?"

"I was trying to do something nice, give her some closure," the Doctor tried to explain, "I didn't think she'd be stupid enough to do what she did."

Eyes narrowing, Aries asked the Doctor to tell her exactly what had happened and the Time Lord did. When he had finished, the red head was shaking as her emotions got the better of her, unable to believe that the Doctor would have done something so idiotic as bringing his companion back not once, but twice to see her father die.

"Aries," the Doctor said tentatively when he noticed a breeze start to pick up around his Nesdra, knowing from seeing it before that she was furious. He couldn't blame her for feeling that way, knowing that he shouldn't have done what he had in the first place.

"You...you complete idiot," Aries exclaimed, slapping the Doctor's hand away when he tried to comfort her and she took a step away from him, ignoring how his face fell at her actions, "What in Merlin's name did you think she would do?! Give anyone the chance to see their father again and of course they'd want to try and do something!"

"Aries, please," the Doctor tried as he took step towards her, "I didn't think she'd do-"

"That's your problem, Doctor. You didn't think!" Aries shouted at him as she backed away, shaking her head, "You knew it was wrong and you still brought her back. What did she do? Bat her eyes with a puppy dog expression and you just couldn't resist?" she spat, unable to stop the words from coming from her mouth as her anger grew.

"What? No!" the Time Lord exclaimed.

"Then what was it? Because I actually thought that you were someone I could trust!" Aries shook her head again, "But you're just like everyone else."

The Doctor froze at her words, feeling as though his hearts had been ripped from his chest. He didn't even care as to where Aries was from in his timeline. All that was running through his mind was that she had trusted him...And I had to do something stupid and broke it, he thought angrily, wanting to kick himself for his stupidity.

Aries turned away from the Doctor, her thought's going to Luka and Mickey as she tried to figure out if there was anyway to fix what the Doctor had done. She started heading back to the boys, only to be stopped when the Doctor grabbed her arm.

"Aries, wait," he pleaded, needing to try and right the wrong he had caused.

The red head spun to face him, her eyes flashing red. "Don't touch me!" she snapped and the Doctor was thrown backwards as her magic reacted to her will.

The Doctor was quick to scramble to his feet, but when his eyes landed where his Nesdra had been, Aries was already gone.

"Aries," he breathed in dismay, never having wanted to hurt her.

His Nesdra was someone whom he had never wanted to hurt, never wanted to upset, and because of his companion, he had just done that. He knew it was a useless and a weak excuse to think that the only reason he had agreed to taking Rose to see her father was because it took his mind of the fact that Aries hadn't agreed to travel with him.

But now...now he had no idea how to fix this.

The Doctor walked around the church, checking any possible exits with his sonic as he tried to figure out not only how to fix the mess his companion had caused, but also how to fix the rift he could feel between himself and Aries.

He glanced towards his Nesdra when he noticed Jackie approach Aries and frowned as he noticed a small boy handing something to the red head, seeing something that looked vaguely familiar to the Time Lord before Aries smiled and nudged the boy towards Jackie. The older boy beside Aries asked her something and she nodded before accepting a baby from Jackie as the older boy followed after the younger.

His frown only deepened at their interaction, never having seen Aries so relaxed around anyone before he quickly looked back to the door he had been checking when Aries got up and glanced in his direction.

The Doctor wanted to apologise to her, tell her how wrong he had been, but even in the short time he had known Aries, the Time Lord knew that it was useless. He had come to realise quickly that, to Aries, actions spoke louder than words, of which she only took at face value. His hand tightened around his sonic, just as a voice cut through his thoughts.

"Excuse me! Mr..." Stuart asked as he and his fiancé approached the Doctor.

"Doctor," the Time Lord replied as he moved off to the next door, not really wanting to talk with anyone. He had too much to do than wasting time talking with these humans.

"You seem to know what's going on," Stuart continued, having followed the man.

The Doctor didn't look up from the lock he was scanning, "I give that impression, yeah," he muttered.

Stuart glanced at Sarah when she nudged him and he frowned. "Eris said that you were the best person to ask, but-"

"Can you save us?" Sarah cut in, not having missed the way the Time Lord had stopped what ever he had been doing at the mention of the red head's name.

The Doctor swallowed as he snuck a peek to where Aries had gone, his eyebrows furrowing as to why people kept on calling her Eris before turning to the engaged couple. "Who are you two, then?" he asked curiously, looking the two up and down.

"Stuart Hoskins," the groom replied.

"Sarah Clarke."

"And one extra," the Doctor added, nodding to Sarah's baby bump, "Boy or girl?"

Sarah ran her hand over her bump as she replied, "I don't know. I don't want to know, really."

The Doctor eyed them for a moment. "How did all this get started?" he asked and Sarah glanced to her fiancé.

"Outside the Big Box Club. Two in the morning," Stuart begun.

"Street corner," Sarah added with a small smile, "I'd lost my purse. Didn't have money for a taxi."

"I took her home," Stuart continued.

"Then what?" the Time Lord questioned, "Asked her for a date?"

"Wrote his number on the back of my hand," Sarah told him and Stuart smiled as he added, "Never got rid of her since. My dad said..."

A reaper screeched outside and Stuart's smile faulted as Sarah's lip trembled as tears gathered in her eyes.

"I don't know what this is all about. Eris wouldn't tell us and I know we're not important..." Sarah trailed off, looking down to her bump.

"Who said you're not important?" the Doctor asked, genuinely shocked by her words and the soon-to-be bride looked back to him.

"I've travelled to all sorts of places. Done things you couldn't even imagine, but...you two...street corner. Two in the morning. Getting a taxi home. I've never had a life like that," he looked back in Aries' direction, just as she turned away from them and back to the carrycot she was sitting beside. He couldn't help but wonder what it would be like to have a life like that with his Nesdra.

Sarah and Stuart exchanged knowing glances before the Doctor looked back to them.

"Yes," he said with a smile, "I'll try and save you."

Aries looked up from baby Rose as the Reapers continued to slam against the walls and windows of the church, letting out loud screeches as they did so.

She was feeling much calmer after her fight with the Doctor, and although she was still angry with the Time Lord and Rose for what they had done, she couldn't really fault them for it either. The red head knew that given the chance, she would have tried anything to save her father. In fact, I did, Aries mused as her eyebrows creased, remembering how she had tried every spell she could think of to save Severus. That was until he had sent her away.

Baby Rose cooed in her arms and Aries shook her head, getting rid of where her thoughts were going. She looked down to the baby and couldn't help but smile sadly, having learnt that Rose had never known her father.

At least I knew my father, the red head thought.

Rieka and Severus landed on the ground in a hidden grove just inside the Forbidden Forest.

The red head quickly shifted back to her less feathered form and was grinning with delight as she watched her father follow not moment's later. "That was amazing!" she exclaimed, hugging her father in her excitement.

Severus stiffened at first, his eyes scanning the woods around them to make sure they were truly alone before he relaxed and hugged her back.

Rieka took no notice, however. She knew the role he had to enforce, but she also knew that the grove had been warded against anyone from Hogwarts. The only humans who could enter it were herself, her father, Dumbledore, and Amelia. Amelia however, very rarely showed up and Dumbledore had ever appeared after he had warded the area.

"Can we go again?" the red head asked, looking up to her father hopefully.

Severus looked up to the sky, seeing the sun had almost disappeared into the horizon. As much as he wanted to spend more time with his daughter, he knew they had to head back. "I'm sorry, Rie, but we have to return. Curfew will begin shortly and you don't want to end up with detention, do you?" he told her gently, holding her close a moment longer before pulling away.

Rieka looked down sadly, but nodded her head. She knew he was right and knew how dangerous it would be if they were caught and Severus had only wanted to keep her safe.

Severus smiled down at his daughter, "Come, I'll take us back," he said softly, holding out his hand.

Rieka looked up to him and smiled as she grabbed it.

They were gone with an almost silent crack.

"Aries?" a voice broke the red head from her thoughts and she startled, waking the snoozing Rose in her arms.

She looked to the voice an realised it was the Doctor. "Oh, er, sorry," she said as she dropped her hand from her necklace and tried to resettle Rose.

"Would you like some help?" the Time Lord asked hesitantly. Although he could see that something was on Aries' mind, he couldn't help but try and get back onto her good side. The last thing he had ever wanted to do was have her angry with him.

Aries glanced at the Doctor before nodding, passing him Rose who was quick to quieten in his arms. A small frown tugged at her lips as she looked away, her eyebrows creasing slightly. "I'm sorry," she said quietly, causing the Doctor's head to snap in her direction.

"Why are you apologising?" he asked, "You haven't done anything wrong."

"I shouldn't have shouted at you earlier," Aries muttered, only to jump when the Doctor gently placed a hand on her shoulder and she looked to him in confusion.

"You had every right to," he told her as he adjusted Rose in his other arm, "I shouldn't have brought Rose here, let alone twice."

"You didn't know she would save Pete," Aries shook her head when the Doctor went to say something else, "It doesn't matter," she told him and the Time Lord frowned.

"It matters to me," the Doctor stressed, though his comment only caused Aries to grow confused again. The Doctor sighed as he carefully placed baby Rose back into the carrycot beside Aries before sitting next to his Nesdra. He hesitated before deciding against grabbing Aries' hand and scratched the back of his neck as he tried to figure out how to say what he wanted to say.

He opened his mouth to say something, but was interrupted when his companion approached them, sniffling and tearful.

"I'd better be careful," Rose said, "I think I just imprinted myself on Mickey like a mother chicken."

Aries frowned at the blonde and was about to get up to check on Mickey and Luka, but her hand shot out and grabbed Rose's wrist when she noticed the blonde reaching out to her younger self. "No," she snapped, pushing Rose's hand away, "Don't touch the baby."

"Why not?" Rose argued back, only to pause when the Reapers outside screeched loudly, almost as if they knew what had almost happened.

"You're both the same person and that's a paradox," Aries explained, glancing to baby Rose to make sure she was still sleeping.

"Oh, and like I'd believe you," Rose huffed, though her anger and jealously towards Aries only grew when the Doctor spoke, agreeing once again with the red head.

"Rose, Aries' is right. We don't want a paradox happening. Not with these things outside. Anything new, any disturbance in time makes them stronger. The paradox might let them in."

"Can't do anything right, can I?" the blonde grumbled.

"Since you asked," the Doctor continued as though he was talking to a dimwit, causing Aries to raise an eyebrow as she watched the pair, "No. So, don't. Touch. The. Baby."

"I'm. Not. Stupid," Rose replied, her eyes narrowing.

"You could've fooled me," the Doctor was quick to snap back and Rose looked away from him, hurt.

"Doctor," Aries spoke up as she glanced between the pair, "Rose didn't know." Rose looked to Aries in surprise as the red head continued, but the Doctor frowned and looked away, "Just as you didn't know that she would save her father's life. It doesn't matter how this started, who's at fault. What matters is how to fix it."

The surprise that had been on Rose's face was quickly replaced by jealousy when the Doctor sighed and glanced at Aries. She could see that the Time Lord was actually listening to the red head and couldn't believe it when he nodded at Aries with a small smile when the red head grabbed his hand.

"But between you and me," Aries added with a frown as she glanced at the doors of the church when another Reaper tried to force its way inside, "I have no idea what those creatures are, nor any idea on how to stop them."

"No way out," the Doctor muttered and Aries glanced at him, her eyebrows furrowing.

"You'll think of something," Rose told the Doctor quietly, only for the Time Lord to frown as he looked to her.

"The entire Earth is being sterilised. This, and other places like it, are all that's left of the human race. We might hold out for a whole, but nothing can stop those creatures," he said as his eyes followed the shadows circling the church, "They'll get through in the end. The walls aren't that old," his hand tightened around Aries' as he continued, feeling rather hopeless at fixing what he and Rose had done, "And there's nothing I can do to stop them. There used to be laws stopping this kind of thing from happening, my people would have stopped this. But they're all gone. And now I'm going the same way."

Aries looked to the Doctor in surprise, wondering what he had meant by his people being gone as Rose spoke, "If I had realised..."

The blonde trailed off when the Doctor looked at her, though he glanced at Aries when she pulled her hand from his, looking at him pointedly. He sighed as he turned back to his companion. "Just...tell me you're sorry," he said, knowing that Aries was right. Rose had no idea that in saving her father would have led to this and he was as much at fault as she was.

"I am. I'm sorry" Rose said sincerely, managing to keep her voice even. Inside however, she was miffed that Aries had once again convinced the Doctor to listen to her. A small voice in her head told the blonde that the Doctor probably wouldn't have even asked if it hadn't been for Aries, that he would have continued to blame her for what had happened, but she ignored it.

She knew that the Doctor wouldn't have stayed angry with her. She was his companion. The one person who stayed with him, travelled with him. There was no way he would have left her behind.

The Doctor nodded at his companion, accepting her apology as Aries stood up with a soft smile as someone caught her eye. He glanced at his Nesdra, only for his eyebrows to raise when a small boy that looked about six suddenly rushed over to her.

"Aunty Eris!" Luka shouted as he hugged Aries, "Mickey told Auntie Jackie that he had ice-cream..." the little boy trailed off when he noticed the Doctor and his jaw dropped as his eyes went wide. "Is...is that the...?" he asked, looking back to Aries.

The Doctor raised an eyebrow at Aries as she nodded with a soft smile to Luka, once again surprised at how at ease she seemed to be around the boy. He didn't have time to question what had changed for her to have become the woman he had met at Downing Street as he suddenly found Luka hugging him tightly.

"Thank you," Luka said, confusing the Time Lord, "You helped save my da-" he broke off with a yelp and Aries was quick to make sure he was okay as the boy let the Doctor go.

Rose rolled her eyes, though she couldn't help but frown at the name that Luka had used. Didn't Mickey mention an Eris before? she asked herself, though she couldn't remember, not really having listened to her boyfriend when he spoke about his own friends.

"What's wrong, Luka?" Aries asked, kneeling in front of the boy as she checked him over.

"He's got something hot, Aunty" Luka explained, looking to the Doctor.

"What do you mean?" she questioned, glancing at the Time Lord as he checked his pockets, only for her eyebrows to raise when he pulled out a glowing golden key before dropping it like it had burnt him.

"It's the TARDIS key!" the Doctor exclaimed in delight as he quickly took off his jacket and used it to pick up the key, "It's telling me it's still connected to the TARDIS!"

"And what does that mean?" Aries asked as she straightened, holding Luka close to her side so he wouldn't run off and get into mischief.

The Doctor just grinned before he dashed off.
