A/N: With the lack of adult-Tamsin in season 4 so far (though that is all set to change this coming weekend) I decided that I had to write this. The pairings are all over the place in the first few chapters, we've got some Doccubus, and we've got some DyBo, with a Valkubus endgame. If you don't like Valkubus don't read it. Simple. Happy reading :)

Chapter One

She had waited many lifetimes for someone like Bo to come along, she hadn't been lying when she told Bo she was unlike anyone she had ever met in any of her many lifetimes. As a Valkyrie her only commitment was to her calling, her duty, what she was born to do. But the Succubus has changed all that. She had been sent to find Bo, take her in, not fall for her. She wasn't sure when she'd actually fallen for her; it could have been as early as the first day they met. In her many lifetimes Tamsin had met many Succubi, she'd had fun with a few. By their very nature Succubi weren't the most monogamous of Fae, feeding off Chi limits the partners that could sustain a Succubus long term. Tamsin knew Dyson struggled; they'd talked about it on one of their many drunken nights out when Tamsin was still trying to get a real read on Bo. She knew that as a Valkyrie, sustaining a Succubus wouldn't be that difficult, as Valkyrie's somehow retain parts of the souls that they take to Valhalla, and Tamsin had delivered thousands. But she was pretty sure that Bo would never feel anything for her other than possibly a friendship, which was more than Tamsin felt she would ever deserve.

Things had been a little strange since Dyson found Bo. Nobody seemed to realise that Tamsin had not tried to kill Dyson, she hadn't really considered what would happen to the wolf as the truck went over the cliff, the only thing that was going through her head was making sure Bo was safe. She knew that Dyson shifted, that's the only thing that saved him, she didn't have the same luxury, she'd given her life to try and save Bo. It had taken just over a week for her to go from baby-Tamsin to adult-Tamsin; Valkyrie's aged quickly through the first week, 30 years in a week. As a species it was all about survival, the quicker they aged the quicker they could get back to their calling. Kenzi had taken great joy in telling everyone that Tamsin was as much of a total shit as a child as she was as an adult. Trick had already explained to everyone that many Valkyrie's supress the memories from their previous lives, it was the perfect excuse for Tamsin not to face up to her feelings or her actions.

Dyson had found Tamsin in a bush the day he went looking for Bo; apparently he had been back to the crash site every day at the same time looking for her. He hadn't pushed her for an explanation about driving him off a cliff; the only one really hung up on it was Kenzi. The human was not buying Tamsin's 'I don't remember' excuse for one minute, apparently Tamsin made her bullshit detector scream. Tamsin knew that Kenzi would be the one to call her on it, which was part of Kenzi's 'charm'. As much as she hated to admit it, Tamsin had become pretty attached to the human. Kenzi had been the one who had tried to ease Tamsin through her growing spurt, even though she had no idea what was going on. She was also the one who saw Tamsin's true feelings for Bo.

The whole gang were at the Dal, though Tamsin was pretty sure she was only there to make sure nothing happened to Lauren. Having just been through her rebirth Tamsin was at her most powerful, most dangerous, it was like having a pit-bull at the Dal, no one even attempted to cause any kind of trouble. Lauren was still hated by a large number of Fae who still thought that she had betrayed them; Tamsin thought she was crazy to come back, especially with the Una Mens around. Crazy or not, Lauren was important to Bo and Bo was important to Tamsin, so Tamsin would do whatever she could to protect the good doctor.

"Are you going to tell her?" Kenzi asked Tamsin as they sat at the bar.

"Tell who what?" Tamsin replied.

"Don't act dumb blondie," Kenzi said, "it really doesn't suit you. Are you going to tell Bo how you feel?"

"Because that will work out well," Tamsin said, "what do you suggest, just walk up to her and say 'hey Bo, I know you think I'm a heartless crazy bitch, but I think I may have fallen for you' yeah, don't think so kiddo."

"So you're just going to let her get back with Dyson, thinking that you really don't care?" Kenzi asked.

"If it makes her happy…" Tamsin replied with a little shrug.

"But what about what makes you happy TamTam," Kenzi said, "you deserve to be happy just as much as everyone else does."

"Some people may disagree with you on that." Tamsin said with a laugh.

"You drove your truck off a cliff to try and save Bo…" Kenzi said.

"Waste of a good truck." Tamsin said, interrupting her.

"Let me finish," Kenzi said, elbowing the Valkyrie, "you drove your truck off a cliff to try and save her, knowing that it would probably kill you, you went against everything you know as a Valkyrie for her… she needs to know Tamsin, if you don't tell her I will."

"Don't you even think about it," Tamsin said, "if she's happy with Dyson, and he's happy with her, then just leave it alone. Wolf-man gets his mate back, means less brooding and sulking, the world is a better place for everyone. Plus that triangle so doesn't need to be made into a square."

"I think you actually underestimate Bo," Kenzi said, "sure she's always thinking with her heart instead of her head, sure she's little miss wonder-snatch, but if she knew how you felt…"

"Leave it alone Kenzi." Tamsin said.

"Leave what alone?" Bo asked walking up to the bar, squeezing in-between the Valkyrie and the human.

Having Bo standing so close was causing Tamsin's mind to spin.

"Tamsin is in lurve." Kenzi said with a smile and a wink.

"I said leave it alone." Tamsin said.

"Oh yeah?" Bo asked, ignoring Tamsin's protests, "who's the lucky… guy or girl?"

"Girl." Kenzi said.

"Seriously," Tamsin said, standing up, "leave it alone. Can I steal your boyfriend to shoot some pool?"

"He's not my boyfriend." Bo said.

"If you say so…" Tamsin replied, walking over to the pool table.

"What's got into her?" Bo asked Kenzi as she watched Tamsin grab a pool cue.

"She's got feelings for someone, but doesn't want to tell them." Kenzi replied.

"Seriously?" Bo asked, "Didn't think Tamsin was one for the whole feelings shit."

"You'd be surprised," Kenzi said with a smile, "talking of feelings, what's going on with you and the wolf?"

"He has a name Kenz," Bo said, "you're starting to sound like Tamsin; you two are spending way too much time together."

"She's actually pretty cool if you give her a chance." Kenzi said.

"I feel like I'm constantly banging my head against a brick wall with her," Bo said, sitting in the seat that Tamsin had vacated, "I mean, I thought we were getting somewhere when we were rescuing Dyson, she was finally starting to open up…"

"Was that before or after she tried to kill you?" Lauren asked, sitting next to Bo.

"She didn't try and kill me…" Bo replied, "much… but that's not the point. She felt she had no choice, we've all been there right?"

"I still don't know if I trust her," Lauren said, "there's still so much that we don't know about her. She tried to kill Dyson."

"No she didn't," Kenzi said, "she knew if Dyson shifted then he'd be okay. She knew she was going to kill herself doing it, but she wanted to keep Bo safe…"

Bo and Lauren just sat there looking at Kenzi with a shocked look on their faces.

"Did I just say that out loud?" Kenzi asked, "That's my cue to leave, excuse me sexy peeps."

Kenzi stood up and headed off to where Hale was sitting at the table near the pool table.

"Why would Tamsin knowingly end her own life to save mine…?" Bo said, looking over at the blonde who was laughing with Dyson about something.

"She's a Valkyrie," Lauren said, "a Valkyrie who was coming to the end of her life-cycle anyway; I wouldn't read too much into it."

"Are you still that pissed about the kiss?" Bo asked.

"Pissed?" Lauren asked, "Not really. Frustrated and confused about it? Definitely. I'm going to head home, are you coming?"

"No, I think I'm going to hang around here for a little while." Bo said with a smile.

"Okay," Lauren replied, "I'll see you tomorrow then."

"Sure." Bo said.

Lauren moved to kiss Bo, who turned her head away from Lauren so instead of a kiss on the lips it was on the cheek. Lauren looked a little confused.

"I'm still not…" Bo started to say, "I don't want to lead you on Lauren, you mean too much to me for that. I just need to figure out what I want."

Lauren nodded and smiled a little.

"Goodnight Bo." She said.

Tamsin saw that Lauren was leaving.

"Do you want a lift home Doc?" she asked.

"I think I can manage on my own thanks." Lauren replied.

"Whatever." Tamsin said with a shrug going back to the game.

It was starting to get late, and the Dal was starting to empty, as Tamsin beat Dyson, yet again.

"Hand over your cash dude." Tamsin said with a smile.

"I let you win." Dyson said, handing her the money.

"You let me win? 4 times?" Tamsin asked with a laugh, "admit it, you suck."

"I was going easy on you," Dyson replied with a laugh of his own, "checking out whether you got the mad skills back after your rebirth."

"All my mad skills are still intact thank you very much." Tamsin said with a wink.

Kenzi made her way over to the pool table.

"TamTam." She said, like a kid who wanted something from their parent.

"What do you want Kenzi?" Tamsin asked with a smile.

"Could you possibly find it in that massive heart of yours to possibly drive home a slightly drunk human and her Succubus best friend?" Kenzi asked.

"I thought that maybe Bo could…" Dyson started to say.

"Bo wants to go home and sleep in her own bed," Bo said, walking over to the table, "alone."

"Ouch…" Kenzi said with a little laugh.

"Burn." Tamsin said, unable to keep the smirk off her face, "I guess I could drop you both off."

"Thanks," Kenzi said with a grin, "you're the bestest Valkyrie ever."

"How much has she had to drink?" Tamsin asked Bo.

"A bit," Bo said with a smile, "but you are the bestest Valkyrie ever."

"Okay," Tamsin said, putting the pool cue back, "Time to go I think. See you at the station tomorrow?"

"Are you back at work tomorrow?" Dyson asked.

"That's the plan," Tamsin replied, "if I spend any more time around Kenzi she'll be changing my entire wardrobe and making me wear funky wigs."

"The younger you looked cute in my clothes." Kenzi said with a laugh.

"And I thought we were never going to talk about that again." Tamsin said, looking at Kenzi.

"I knew we should have taken photos." Kenzi said to Dyson.

Both Kenzi and Dyson laughed as Tamsin rolled her eyes.

"Let's go meat-bag," Tamsin said to Kenzi before looking at Bo, "you ready Succubus?"

"For you to drive me home? Always," Bo said with a smile, "are you going to tuck me into bed too?"
