"I've got something to do!" Remus said, sitting bolt upright in his marital bed.

"Unless your next line is 'You!' or "Change Teddy's nappy and give you a lie-in, my love!' I don't want to know." Dora hissed in a hushed whisper, one eye on the sleeping green-haired baby nestled under her arm.

.

"No." Remus assured her, thrusting back the covers and flinging himself out of bed. "It's brilliant. I don't know how I could possibly not have thought of it before… Actually I really don't know how none of us could have thought of it before… I have to tell you, now."

.

"If none of 'us' have ever thought of doing it…" Dora yawned. "It's either a really stupid and bad idea or it's impossible. Lie down, think quietly, then tell me which when it's actually the morning."

"No. Shush." He hopped across the room, tugging on trousers, stumbling into the chest of draws as quietly as he could. "...I'm doing this today!"
.

"Doing what?" Dora growled. Remus looked at her, an eyebrow quirked thoughtfully.

"If you tell me one more time that you love it when I 'growl' I am going to follow up with a bite. You Comprehend?"

"Totally. Listen Dora; can you take Teddy to your mums and go to work as normal. I'll be back in time for dinner… But you might want to make extra."

"No." Tonks assured him, trying hard not to look too interested.

"Yes!" Remus assured her. Tonks wrinkled her nose. It was not often that her husband's golden eyes sparkled with such uncrushable enthusiasm. Realistically they never did... Unless he was very drunk and acting inappropriately. Irritably she eased her arm from under the sleeping baby and sat up.

.

"Right." She said. "What's your stupid idea?"

"It's not stupid." Dora smiled at him.

"Alright, what's your idea that's 'so brilliant that not one of 'us' have ever before thought it was a good idea to try'?"

"Right…" He was actually breathless in his excitement.

.

"...Okay." He said. "I'm going to steal a Time-turner, go back in time, and stop Sirius dying."

.

"Oh… Shit." Dora got out of bed, carefully, and put her arms gently around his neck, kissing his scared cheek. "Remus, love." She said. "You do know that's impossible. You do know. And you're right, of course. Hundreds of people would have done it, if that worked."

"So?" Remus said, wriggling her off. "I don't care. I'm still going to do it."

.

Dora watched him pulling on his socks and shoes, jaw set. "…You were dreaming, Remus love." She said, calmly. "…But I hope it was a nice dream, you know… Sometimes I dream about Alastor being alright. Often, really. Or just that I'm talking to him again… And my dad."

"That's fine." Remus snapped, standing up again. "Don't care right now. Go to work. Act like everything's normal."

"Everything is normal." Dora said, her patience rapidly wearing thin. "All the Time-turners were destroyed; that day, Remus, the day Sirius died. They were all destroyed and they haven't made any more of them. And even if they had, you can only go back twenty four hours."

.

"Going back in time is going back in time." Remus interrupted her, quickly. "You can either go back through time or you can't. They're just capped it at… It's forty eight hours actually. I have researched this, you know? You only have to break off the little gold pin at the top and you can go back as far as you want."

.

"Why don't you just travel back to Voldemort's conception and stop him ever existing?" Dora pointed out. "Apart from the fact that it's against the law and you can't actually change anything."

"That's a lie." Remus assured her, with a bitter laugh. "This is blatantly a lie. If you can't change anything why use them at all? Why not just look at photo's or dip your head in a pensive. And there are Time-turners at Beaubaton's and Durmstrang. They weren't destroyed. They were both given to fifth year students at the start of this term. Fred Muller and Jacque Noir to be precise."

.

"You found out which children have the Time-turners!?" Dora asked. Remus studied her in silence. "Remus… What you are talking about is so against the law. You would go to Azkaban. And it's illegal for a reason. If you actually… If you actually change the past you change the present. You could destroy the world!"

"Well, I'm not going back to destroy Voldemort before he was born. I'm not doing anything really. I'm just going to stop Sirius… To stop him dying."

"But that is a big thing." Dora pointed out, firmly. "For God's sake, Remus. That's a massive thing. If Sirius hadn't died… Harry would be different. He might not be out there destroying Horcruxses at all. You… You would be different, Remus. What's to say we would even have got married? …You and Sirius might be out there destroying Horcruxes with him."

.

She swung away, glaring at yesterday's clothes as she yanked them on. Going over to the bed and looking down at Teddy.

.

"…If you change the past." She said, quietly. "It might be the ultimate outcome of the war between good and evil that you change, Remus. But you might sidestep destroying the world. You might not even destroy us, although I doubt it… But I guarantee that that night when you were breaking your heart over it all and we conceived Teddy… That will never happen, Remus. If you stop Sirius dying, Teddy won't be here when you get back... If you even came back."

.

They finished dressing in silence, the tiny green haired baby slept, pink cheeked, in the bed behind them. "...I'm going to work." Dora told him finally. "Take Teddy to my mums and practicing not being such a tosser." She turned to flash a yellow eyed glare at him but Remus was sitting in the end of the bed, his face buried in his hands, and didn't see.

.

Dora ignored him going over to brush the gentlest kiss against the sleeping baby's cheek. He smelt like milk and love, and just faintly of a rather wet night-time nappy. Her husband, poor excuse that he was for one, was still hiding in his own hands. "…Poor you." She said, darkly. "You mess with time and Teddy won't be here when you come back. I know Sirius was great but was he that great?"

"I wish I hadn't told you." Remus said, sullenly enough to make her crack an angry smile.

"You Pratt!" She told him. "…And grow up!" And she stalked out, purposefully slamming the door loudly enough to wake the baby.

.

.

Enraged red eyes flicked open and an equally red mouth opened in a screech of annoyance. Muttering rudely about his insensitive wife Remus scrambled across the bed, propping his son into the crook of his arm and stuffing an enchanted bottle into his mouth. He watched the baby feeding, squeezing his shirt with a tiny perfect hand. Red eyes drifting through a rainbow of pretty colours, as they blinked blissfully.

.

Remus thought about James, a father at barely twenty, trying to explain what it meant. A father. Trying to explain to a nineteen year old Sirius, who barely understood how to look after himself, and Peter, who must have already swapped sides. He shivered, clutching the baby tighter, looking at his own scarred hand, curled around the stripy yellow and black babygro. His son looked like a bumble bee. Like the cutest sweetest bumblebee ever, being held in the clawed scared hands of a beast, which would happily rip him to pieces like a rag doll, were they to get stuck in the same room three nights from now.

.

"I'm a father!" James had said. He'd said it over and over again. He used 'dad' afterwards, but just that time Remus thought he'd forgotten that he liked 'dad' better. "I'm a father." He'd said, over and over again. They had all been barely twenty. The war. The prophecy. He had been a father.

.

"...I had no idea, Prongs." He whispered, trying to blink away the sea of tears. "I had no idea."

.

He looked down at the baby that had stopped its eye kaleidoscoping on a sparkling silver grey. Remus studied those eyes in silence until the baby blinked and re-opened them transformed into an inky blackness that looked so like Snape's that Remus laughed.

.

"...Daddy is going on a journey." He said, sliding the baby onto the bed and grabbing a nappy, changing Teddy with practiced ease. "Look I got hold of this last week, Ted. Do you know what it is?"

.

He let the chubby fingers play with the Time-turner as he fastened the popper-studs on the bumblebee all-in-one. "...Right Teddy." He said, stand over the bed finally. "It this works… This will work. ...Come here little man." He scooped up the baby and looped the fine golden chain carefully around both their necks, pressing his son against his heart, carefully cradling the back of his neck for support. "You didn't think I'd leave you behind, did you, Teddy?" He said. "Let's go get Sirius."
