"What are we doing here again?" Martha Jones asked, looking up at The Doctor, who was holding a large and to be honest, ridiculous contraption in his arms, fiddling with a dial on it and frowning. They had just stopped off when The Doctor had picked up large amounts of residual time energy that shouldn't – that COULDN'T exist. They were supposed to be going to the Moons of Selroth, but The Doctor had insisted that this was a matter that couldn't wait.

"Need to figure out what's causing the energy – it's extremely strong –it's making my timey wimey detector go all over the place." The Doctor said, only half listening to what she was saying, more intent on talking to himself. "I mean, it doesn't make any sense, not really – I mean I've honestly never heard of something that can leave time energy on this scale – nothing except the TARDIS, and that type of energy is completely different. Controlled. This – This is completely different."

Martha wrinkled her nose and looked around the garden. It was untamed from lack of care, and littered with rubbish that had been carelessly tossed in by people passing through. That wasn't what bothered her though - the weird crying angel statues sent shivers up her spine. It reminded her of a graveyard.

"-gets stronger the closer we get to the house," The Doctor was saying, and Martha focused on him. The sooner they found out what it was, the sooner they could leave.

"So, into the house?" Martha offered, and The Doctor spared her a grin.

"Into the house!" he agreed, cheerful as ever.

Together, they walked into the run-down mansion, and The Doctor's 'timey wimey detector' was going somewhat haywire. He frowned at it, and in his usual method of hitting things until they worked, he smacked his hand against the side of it, hard.

"Come on –come on!" he urged it, before letting out a low moan, like a petulant child. "No, no, no!" he cried, looking very unhappy. "It's died out!"

"What does that mean?" Martha asked, attempting to peek over his shoulder.

"It means that the energy in here was too strong for it." The Doctor said, and Martha noticed a grave note in his tone. "I mean, granted, it wasn't finished and its main purpose ended up being able to just boil eggs, including the chickens within a large scale radius, but it should have lasted out whilst looking for residual energy. The fact that it didn't conveys that we are dealing with something very, very powerful, Martha Jones."

"Reassuring," Martha mumbled, rolling her eyes slightly. Something powerful and something alien, if she was guessing right; which she was sure she was. Martha wrapped her arms around herself, shivering at the strange breeze that ran through the empty and derelict house.

It was an uncomfortable, almost impossible feeling, but she felt as though she were being watched, and she didn't like it.

"Doctor, whatever's making all of the Time Energy… could it still be here?" She asked, looking up at the Time Lord, who was now shaking his contraption, lips pressing together in an annoyed pout before he looked over at her.

"I'd think so," He admitted, before he frowned. "Thing is; with something this strong, I'd expect to have sensed some kind of movement by now." The Doctor's eyes narrowed, and Martha grimaced slightly. "Keep an eye open."

"Will do," Martha muttered, slowly running her hands up her arms, before she glanced into another room. It seemed empty enough, and she moved over to the window, glancing outside to the overgrowth that seemed almost like an urban jungle. Her gaze was drawn to the angel statues once more, only…

"Hang on…" Martha murmured quietly. "Those statues had their faces covered before..." Only now, they seemed to be looking right at her, and Martha felt a shiver run down her spine. Unnerved, she turned away and headed out of the room, trying to shake the uneasiness she felt.

It didn't take her long to find The Doctor again, as he was crouched in the living room, glaring at the scanner as though it was the reason for all of his problems.

"No luck?" She asked, raising an eyebrow, and he frowned up at her petulantly.

"No, and I don't understand why!"

Martha shook her head and turned, only to freeze, her breath catching in her throat, as fear welled up inside of her. Swallowing, she reached behind her and tapped The Doctor on the shoulder quickly. "Doctor. Doctor! the statue!"

"What?" The Doctor asked, distracted, and turned. He froze when he saw it, abandoning his detector in favour of grabbing Martha's arm. One of the angel statues stood in the way of their exit, hands covering its eyes. "Don't blink Martha, do you understand? Do NOT blink!"

"What is it? Why can't I blink?" Martha asked quickly, keeping her eyes open wide.

"Because if you don't blink, they can't move; they can only move if you look away or blink." The Doctor began to pull her around the angel, keeping his gaze fixated upon it, trying to move around it without touching it. It was difficult, but he managed. "We need to get out of here. Now."

"No complaints here," Martha replied, her eyes watering from the strain of keeping them open. The Doctor glanced behind him to make sure none were trying to sneak up on them, but unfortunately, Martha couldn't hold back the urge to blink any longer, and did so, only to let out a shriek as she did. The statue had turned completely to face them, arms outstretched, face twisted in an expression of grotesque anger. The Doctor spun around again, eyes wide, and continued to guide Martha backwards.

"Come on, Martha – we just need to get to the door, and we're home f-"

Martha let out a noise of discontent and grabbed at her head, slumping down onto the ground, curling up slightly. Her head was both pounding and spinning, and she felt, to put it bluntly, terrible. She risked a glance up to see that The Doctor looked a little better than she did, but obviously was uncomfortable.

"What the hell was that?" she asked, rubbing her temples with a cringe.

"Basically, travelling through time without a capsule," The Doctor sighed, rubbing the back of his neck with a groan. "Not the easiest way to travel, but the motion sickness sensation and headache will wear off."

"How did we manage to do that? What were those statues?" Martha inquired, head tilted to one side.

"Weeping Angels," The Doctor informed her. "I thought they were just a legend, to be honest. They're stuck in a sort of quantum lock, which means basically they have the ultimate defence mechanism – when they're looked at – they're stone. Now stone can't move, but you can't kill it, either. But look away – and that's when they uncover their faces. They're lightning fast. One touch is all it takes."

"To what? Make us travel through time? Why would they do that?" Martha asked.

"Residual time energy," The Doctor scowled, pinching the bridge of his nose. "I should have seen it. Weeping Angels are the only creatures in the universe that will 'kill you nicely'" he said with obvious distaste as Martha reached into a nearby bin to pick up a newspaper. "They send you back in time and basically let you live to death. You live out your whole life in another time, and they feed on the time energy left behind. They won't get much on us though, seeing as we're time travellers – but if they find the TARDIS, they'll stop at nothing til they break her open."

"So they send you back in time?" Martha asked for clarification, obviously disbelieving.

"Yep!" The Doctor popped the 'p' "So Martha Jones – when are we?"

"Just where we were," Martha replied, holding out the newspaper. "2008. Same day and everything."

"What?" The Doctor asked in disbelief, snatching the paper from it and scanning it. "But that's impossible! We can't be!"

Martha shrugged, leaning back slightly and smiling. "I guess not – But it's a relief right? Now we can just walk back to wherever we were and get the TARDIS." She reached into her shirt, searching for her TARDIS key, and her eyes widened. "Doctor. My TARDIS key – it's gone! I had it before we went into that house – I know I did."

The Doctor glanced up at her in alarm. If the angels had a TARDIS key, then that was very, very bad. He could ponder why the angels hadn't sent them back in time later; for now, the important thing was getting back.

"Right then, Martha. Let's get back, quickly. We need to get the TARDIS away from the… angels…" The Doctor trailed off, having turned his gaze towards the sky briefly, only to feel the world stand still around him. There they were; huge zeppelins in the sky, a sight he never expected to see again.

"It's beautiful!"

The Doctor turned sharply, but no-one had spoken. It was just a memory. Still, he could recall her face clearly, staring up in wonder at those giant balloons – and suddenly, several emotions hit him all at once. The crushing pain he felt at losing Rose was the most apparent, her face at Bad Wolf Bay still haunted the little sleep he managed to get. The other emotion, was hope. If he was actually in Pete's world, then Rose was here.

"Rose," he murmured softly, under his breath, and though he almost didn't dare to hope, lightness bubbled up into his chest.

"What?" Martha asked, looking at him questioningly, and The Doctor blinked, having almost forgotten she was there.

"Oh, er – the sky," He said, pointing up. "Not exactly like your London, is it?"

Martha looked up, and her mouth fell open in shock, staring at the zeppelins. "…Not exactly." She finally managed, and The Doctor allowed a small smile to cross his face.

"No, we've crossed universes, rather than time." The Doctor surmised, standing up and stretching slightly. "No idea how or why, though. Terrible, really, universes could go boom at any minute. The angels definitely ARE supposed to send you back in time – they shouldn't be able to send us through dimensions unless there's a tear between them and if that's the case, then that is very, very bad."

"So what do we do?" Martha asked, also standing up, eyebrows raised. "How do we get to the TARDIS if we're in another universe?"

"Give me your mobile." He requested, and ignored her look of confusion as he took it from her. He pressed his sonic against it, waiting until it quickly ran through all of the network – no longer Cybus, at least – before it finally showed a face he had sorely missed.

Rose Tyler. Alive and well. That was all he needed to know.

"Come on," The Doctor said cheerfully, tossing Martha's phone back to her. "I know just where we're going to go. Luckily for us – I've been to this universe before, so I've got some friends who'll help us out. Hopefully they're still living in the same place – it would make things easier."

Martha just shook her head, knowing she'd never get a straight answer out of him, and followed. As long as they managed to get back to their own dimension, she'd trust in The Doctor, like she always did.

"So these mystery friends of yours live here?" Martha asked, looking at the huge mansion, obviously impressed. "Not bad."

"Old Pete does well for himself," The Doctor agreed with a grin, ringing the doorbell and bouncing up and down. The only thing that was running through his mind was her name. His Rose.

"Comin'!" A voice called out, and The Doctor perked slightly. Not a voice he'd thought he'd miss, and grinning, he spread his arms out when the door opened.

"Jackie!" he beamed, darting forward to sweep the older woman in a hug, only to receive a sharp blow on the cheek, sending him reeling for a moment, shock plastered on his face. "…OW!" He finally cried, gripping his cheek and staring at Jackie like a wounded puppy, who was staring at him with wide-eyes, a hint of anger in them. "What was that for?"

"I don't know what kind of alien you are, or what you're playin' at… but you better clear off right now!" Jackie warned, glaring at The Doctor, who still looked a little wounded.

"What? Jackie – Jackie it's me – really, truly honestly me!" The Doctor insisted, holding his hands up defensively, as Martha looked on in bemusement. "Blimey, have you been practicing your swing?"

Jackie continued to glare at him for a moment, before she took him in and narrowed her eyes slightly. Finally she gasped, hand covering her mouth. "Oh my god, it's you! It's really you! But I thought you said-"

"Long story," The Doctor assured her with a sheepish grin, rubbing his cheek. "Can we come in?" he hoped he didn't sound too eager. Jackie raised an eyebrow, able to see right through him.

"She doesn't live here anymore," she told The Doctor gently. "She moved out, shortly after the thing in Norway." The Doctor slumped noticeably, and Martha felt a wave of familiar jealousy wash over her. Who was 'she'?

"Oh." The Doctor said morosely. "Where does she live now?"

"Not too far actually," Jackie mused. "She decided to stay in London – wanted to stay close to Torchwood – she's pretty much the head of the thing now, right after Pete. She…She's done a brilliant job. Saved the world a few times you know," she finished the word there, but the sentence was left hanging, and he knew what she had held back saying.

Without you.

"Of course she did. Rose Tyler, Defender of the Earth." The Doctor mused, and didn't notice Martha tense up beside him. Rose. He'd come here for Rose – the girl who cast a huge shadow. Martha knew her jealousy for the girl was misplaced – having never met her, but she couldn't help it. It was obvious The Doctor was head over heels for her, and she wanted it to be her.

"She stops by here after work, though." Jackie offered, something in her expression softening. "Some come in, I s'pose, and meet Tony." She turned to Martha, fixing the woman with a steely look. "Who's your friend?"

"Martha Jones!" The Doctor said cheerfully, bouncing inside the house. "Travelling companion. Who's Tony, again? Toooooony? Hello?"

"He's two months old you nonce." Jackie sighed, rolling her eyes. "Didn't take you long to replace our Rose then, did it?" she asked flatly, and The Doctor tensed.

"I could never replace Rose." He said quietly, turning to Jackie. "But I was tired, Jackie. Tired of being alone. I needed a friend – Rose was…is, very special to me. No-one could ever replace her."

Martha looked down at her feet, feeling something inside of her break. She always knew she was never a contender to this Rose girl. No matter how hard she tried. She moved past Jackie into the house, pushing back her emotions and lifting her head with a smile.

"It's true – the amount of times he's mentioned her to me," Martha joked lightly. "No way anyone could ever replace her – I haven't even met her yet, and I know that much."

Mollified, Jackie nodded her head and shut the door. "Alright then," She decided. "I'll go and get Tony – make yourself comfy in the lounge, and you can tell me why and how you got back here."

"Brilliant," The Doctor said brightly, moving into the lounge and sitting down on a couch. Realistically, all he wanted to do was find Rose and cling to her, resolving to never let her go again. He could run off to Torchwood – but given how large that place was, there was no guarantee he'd even find Rose amongst the chaos. For now, at least, he would wait. Martha sat opposite him, avoiding his eyes, and The Doctor wondered what had gotten his companion so down-hearted.

Shaking his head, he leaned back into his seat and considered Rose, his pink and yellow human. That smile – oh he'd missed that smile. It made him giddy to think that soon he'd be seeing it again. When he had her in his arms – oh right where she belonged, he'd find a way to get back to their own universe. Torchwood was resourceful, that much was true. If there were holes appearing in the fabric of the universes, then it was most likely Torchwood had a device that could allow them to travel through. The dimension hoppers might be too risky, but he could probably work from there. He couldn't leave Martha stranded here, after all. If Rose wanted to come with them, which he desperately hoped she did, he would bring her with him. The TARDIS would love to have her home.

Smiling slightly, The Doctor leaned back and waited for Jackie to return.
