Just another take on a Tonks is a werewolf story. And I can not deny, I love the idea of mates among werewolves and have seen it often in fics with these two.
It'll hopefully span from OoTP-DH.
Joining the Order had been Moody's idea. He had approached her, asking if she was interested. Of course she was, she didn't have much to do with her life otherwise, and he had said she might finally be able to use the Auror training she received.
Tonks had been surprised when Moody kept in contact with her even once he was 'retired' officially. She had once asked why he still wrote to her, but he simply said she was still his protégé, and that had been that.
When she had gone to her first meeting, she had issues concentrating. She kept thinking about the second full moon she had ever experienced, when she had met another werewolf. After she had fled and transformed back, she looked deeper into werewolf facts and myths.
She then realised she had just met her life mate, and she wished she had read all of this before the moon. She wouldn't have fled the wolf and her strange feelings if she had.
During the meeting, she realised she was feeling the same pull. Something kept telling her the same thing over and over.
He's here.
After the meeting, she left with Moody and Kingsley and simply couldn't resist asking.
"Is there another werewolf in the Order?" She asked as they walked towards the park across from Grimmauld Place.
Kingsley looked at her strangely for a second. "Uh, yes, it's Remus. I assume that's why Sirius introduced you two- you didn't know?"
"No..." She said slowly. "I just know there was another werewolf there, but-"
"The scars didn't give him away?" Kingsley asked.
"Well, Mad-Eye has scars too, but he's not a werewolf.'' Tonks said, and Moody grunted.
"Yes, well, the difference between werewolves and Aurors is that Aurors don't have self inflicted scars." He said.
"Mine aren't self inflicted." Tonks said.
"You've also been taking Wolfsbane since your first full moon." Kingsley said. "Others aren't always so lucky."
The next day, there was another Order meeting. Remus wasn't sure why they were having them so frequently, but part of him hoped Tonks would be there. If she was, he wanted to talk to her again, just to see if he could figure out if she was the werewolf or not.
The full moon was only four days away now, so when she arrived, he tried to see if she had started to look ill at all. Perhaps she was able to morph it away?
Again, Remus was almost ashamed he couldn't pay attention. She had ended up sitting right next to him, and he could feel it. The pull was there once again, stronger than ever. It was her. She was his life mate.
He only caught bits and pieces of the meeting, because he felt so focused on the woman next to him, and the fact he didn't feel well. He stole glances at her a couple of times, Sirius catching his eye at point and simply hiding a grin behind his hand before turning away from Remus.
Sirius wanted Harry here as soon as possible, but Dumbledore insisted they wait a while- he was safe with his Muggle relatives. Hermione would be arriving the day after the full moon, and Dumbledore said two Order members should go and pick her up to bring her to this address. Remus was surprised when both Sirius and Kingsley suggested Remus and Tonks do it, but they agreed anyway, and he realised Tonks hadn't been paying attention to the meeting either when her eyes widened and she had to ask what they'd be doing.
After the meeting, Remus was able to make an excuse using Hermione's arrival for the two of them to talk alone. They went upstairs to the sitting room, and as soon as the door shut, he spoke.
"It's you, isn't it?"
She turned to him, smiling slightly. "It's me." She said. "You felt it too, then?"
Remus nodded.
"I didn't realise that would actually happen, I read that sometimes the life mate isn't... well, that if you were mine, I wasn't necessarily yours."
Remus nodded again. "I read that that has happened." He said. "However, wouldn't that defeat the purpose?"
She shrugged. "I suppose it would." She said. "So, what happens now?"
"I don't know." Remus said. "I suppose we actually discuss Hermione's arrival-"
"I meant with us, Remus."
"Nymphadora, we've barely met-"
"It's Tonks."
"Tonks, then. We've barely met, I don't think anything happens for us now. After all, we know nothing about each other."
"But there's nothing stopping us from getting to know each other, right?" She asked.
He smiled slightly. "I suppose there's not." He said. "I do wonder, though, is there a difference in how we both feel? Because you don't look ill-"
"No, I don't feel too terrible either." Tonks said. "And of course there'll be differences between us."
"Oh?" Remus said.
"Of course there's the headaches and body aches and God knows what else I can blame on the moon, but it's manageable. Possibly because I've always had Wolfsbane, I'm not sure." Tonks said, and then she smiled. "This is good, we're learning about each other."
"I'd like to be honest with you though, I'm not very interested in a relationship-"
"Hey, I didn't mention a relationship. Even so, that's not going to happen tomorrow, I can promise. Like I said, we're mates, we may as well get to know each other. Even if it's just as friends."
"You know that it's unlikely we'll be able to maintain just a friendship, right?" Remus asked. "From what I've read, mates don't always have a choice."
She shrugged. "So we shag every once in a while, we don't have to get married."
"Werewolves don't get married."
"Humans do."
Remus stared at her for a moment. She was the complete opposite of him. How on Earth did book-loving, cardigan wearing Remus Lupin end up life mates with the pink haired and combat boot wearing Nymphadora Tonks?
They were so different, he was now simply curious about how they'd ever be compatible. Wasn't that the idea of a life mate? They'd be similar to soul mates, and the two would fit together like a puzzle?
If that was the case, Remus suddenly found himself very interested in this particular puzzle.
Remus found himself a little disappointed when he didn't see her again until the morning after the moon. Kingsley had stopped by to give Sirius an update on where he had last been 'spotted', and had said that it wasn't uncommon for no one to see Tonks for the three days leading up to the moon.
Remus could understand that, there had been times when he was younger where he did the same, after James and Lily had died and after he had left Greyback's pack at the age of twenty four, nearly three years after he had lost everyone he had cared about.
He had just gotten up after getting a couple hours of sleep, and had met Sirius in the kitchen. Sirius quietly shoved a plate of bacon and eggs towards him.
"The Weasleys are joining us today." Sirius said, turning back to the Daily Prophet.
"For how long?" Remus asked as he began to eat.
Sirius snorted. "You really weren't paying attention, were you?" Sirius asked. "So it is Tonks, then?"
Remus shrugged. "How long are the Weasleys going to be here?"
"The rest of summer." Sirius said. "And then Hermione as well, but..."
"No Harry yet."
"No Harry yet." Sirius said with a nod. "I'm tempted to turn into Padfoot and go over there myself-"
"That would just cause more problems." Remus said. "Besides, if you were a Muggle, how would you react if a dog strolled up to your door and rang the bell?"
Sirius laughed. "Well, when you say it like that..."
There were slow footsteps on the stairs, and they looked up to see Tonks descending the stairs slowly. "Kingsley told me the Weasleys were arriving today." She explained. "I figured I'd ask if you two wanted help getting rooms clean."
"Oh, that'll be an easy task with two very sore werewolves." Sirius said. "You better good at magic, kid."
She rolled her eyes at him, sinking into a chair. "It's not bad." She said.
"No injuries, then?" Remus asked, noticing a dark bruise on her cheek.
"Well, bruises." She said sheepishly. "And I keep breaking the same three ribs every month."
"The same three?" Sirius asked, and she nodded.
"What about you, Remus?" Tonks asked. "Are you alright?"
"Just bruises." Remus said. "I haven't broken bones during transformation for a few years now."
"So, you're saying it gets easier after a few years?" She asked, and he chuckled.
"Ugh, you two." Sirius said. "If that's how you flirt, Tonks-"
"I'm not flirting!"
"-you need to work on it." Sirius finished. "Are you hungry?"
"No, that's always the second thing Mum does after a full moon, she forces me to eat." Tonks said.
"What's the first thing she does?" Sirius asked.
"She heals my injuries, even though I could do it myself-"
"Good ol' Andy." Sirius said. "She hasn't changed much, I assume-"
"It's the Healer thing." Tonks said. "She can't help it."
"So, is she still the nosy Andy I used to know?" Sirius asked. "Does she know about...?" He gestured to Remus.
"Yes, but no." Tonks answered. "If I mention it, she'll immediately ask when her first grandchild will be born.''
"Well, when will her first grandchild be born?" Sirius asked, and Remus felt his cheeks growing warm.
"Oh! Never." Tonks said, glancing at Remus. "I'm sorry, I'm just not- I don't want children, Remus, I hope you don't."
"Like I said, I don't want a relationship at all." Remus said.
"I thought life mates had no choice?" Sirius asked.
"Obviously we have a choice on whether or not we get together." Remus said. "A lot of times, mates just do, sometimes they simply don't. I think it depends on how much the werewolf lets himself or herself be controlled by the condition."
"I mean, I'm just throwing this out there, but can you imagine a half werewolf Metamorphmagus?" Sirius asked.
"Can you imagine a full werewolf Metamorphmagus?" Tonks asked.
"Alright, I'll rephrase. Imagine a kid who is a Metamorphmagus."
"You met me when I was four."
"You're making this bloody difficult." Sirius said. "I'm just trying to get my best mate shagged-"
"I never said that wouldn't happen." Tonks said.
Remus cleared his throat loudly, standing. "Should we get those rooms clean?" He asked. Sirius and Tonks nodded, and they made their way upstairs.
By the time Molly and Arthur arrived with four of their children- Bill was at work, Charlie was still in Romania and Percy hadn't been in touch with his family for a while- they had gotten three rooms clean. Ginny would be sharing with Hermione, and Sirius had somehow convinced Tonks(with barely any argument from her) to stay a few nights or simply move in. Tonks had decided she'd stay a few days at first, because she hadn't seen most of the Weasleys for a few years and figured it'd be nice to spend time with them again.
The twins and Ron would share a room for at least one night, and Ginny and Tonks would share for that night as well, and then Molly said she'd have her children get involved in helping with the cleaning of the other rooms the next day.
The next day, Molly was true to her word. She had the twins, Ron and Ginny cleaning for most of the day, telling Sirius, Remus and Tonks to do whatever they had to do for the Order. Unfortunately, they didn't have much to do, and they ended up helping with the cleaning after a couple of hours, before Remus and Tonks had to leave to get Hermione.
"Are you alright to Apparate?" Remus asked as they walked to the park across from Grimmauld.
"Would you suggest we fly instead?" Tonks asked, and Remus shrugged.
"I didn't like to Apparate right after a full moon for a while, I still try to avoid it if I can." He said. "I just wanted to make sure you're comfortable with it."
"I'm comfortable with it, Remus." She said, and he held out his hand. "We're going by Side-Along?"
"Well, if you prefer not to..."
"No, no, it's fine." She said, taking his hand. "We have to Side-Along Hermione back anyway, don't we?''
Remus nodded, and they disappeared with a crack, reappearing in an alley behind a row of homes. Remus led her up the alley, turning onto a new street.
"Do her parents know we're coming?" Tonks asked.
"No, I figured we'd surprise them." Remus said, and then he chuckled. "I wrote to them the other day to tell them who I was and when I'd be arriving to get her."
Remus led her up a path and onto a porch, ringing the doorbell.
"They're Muggles, right?" Tonks asked, and Remus nodded.
"Yes, why?" Remus asked.
"I just wasn't sure." Tonks said. "I thought Hermione was halfblood at least, if she's as brilliant as Ginny and the others have said."
"Lily was Muggleborn, and she was brilliant." Remus explained.
"Oh, not that I meant anything bad, I just-"
"I know." Remus said as the door opened.
Hermione's father was tall, his hair the same shade of brown as Hermione's. Remus guessed that if it were longer, it would probably be just as curly as well. "You must be Remus Lupin, then." The man said, holding out a hand. "James Granger."
Remus shook his hand, and then gestured to Tonks beside him. "This is Nymphadora Tonks-"
"It's just Tonks." Tonks said, shaking James' hand.
"Hermione's almost ready, she just misplaced a book." James said after he released Tonks' hand. "Come in, you can meet Kathleen."
