A/N: It get's a little rough (AKA violent) in this chap. You've been warned.

Tamsin was in bed with Bo. Bo was spooning with her from behind and they still had on their nightwear.

Tamsin nuzzled closer into her as Bo purred with her head propped up, "Hey Tamsin, if you want to get any closer to me, we may need to take our clothes off."

Tamsin huffed out a laugh, turned around to face Bo and her deep brown eyes and then just glanced to the side with a smirk, "Well, it depends on what you are trying to accomplish. For succu-sex, yes, but *I* am trying to create a fire by rubbing 2 things together, in this case, our bodies."

Bo smiled sincerely but then a coy grin washed across her face, "Sounds nice. But you can create a fire without all that rubbing."

"Oh really?" Tamsin challenged gliding her finger tips down Bo's forearm, "So you think you can get me to soar without laying a single finger on me?"

Bo raised a brow and rose to the challenge, "I sure can. You underestimate me, Valkyrie. You believe me right?"

"Sure. NOT!," Tamsin huffed out a laugh, "It's like saying I can kill someone with just words?"

"Want me to show you?" Bo asked huskily.

Tamsin smirked and pecked Bo quickly, "Be my guest."

Bo glided her hands just above her without touching her and amazingly, the expectation alone was just turning her on.

'Now tell me all your dirty little secrets about what you want to do to me,' Tamsin whispered into Bo's ear. Oddly enough it sounded like someone else was saying it but it was in her voice.

Tamsin couldn't hear what Bo was whispering back to her but it was as if she was talking to herself. Reacting to what she was saying.

'Oh frack. Yes, Please expose me succubus! Touch me. Caress me.'

Tamsin's hands began to move freely on her own body even though she was mostly asleep.

'Stupid dense doctor! She's not even considered competition.'

'God your hands …. Touching me …. Ahhhh… so sensitive… tingling ….. please MORE!'

'Yea please! Yea yea yea… More tongue! Ahhhhh assaulting me! FUCK! SACK ME BO! Dominate me!'

'Oh crap! Ahhh ahhh ahh! You know how I like it. RAVAGE MY LAND! Yeeeeeeeeeeeeeeeeees!'

'Ahhhhhhhhhhhhhh!'

Tamsin was at her own breaking point finally waking up with her hands feeling like they were not under her own control, taking her the rest of the way.

Tamsin yelled out to Bo and enjoyed the ride. It was a violent release for Tamsin and it was unlike her.

At the end she was totally spent and wondered what got into her but exhaustion took over all her muscles to which she relaxed and slumped back into bed.

Right as she drifted off her heard a voice that sounded like herself reaffirming, 'So that's what love feels like.'

Tamsin smirked at the truthfulness of that statement and drifted off to blissful sleep once more.

A couple hours later, Tamsin shot up and wondered what just happened. She knew she brought herself to peak, but why?

Sure Tamsin thought of Bo a lot, but not in the way she expected. It seemed like she was living in someone else's thoughts. Someone that sounded just like her.

WAIT. Tamsin mused. The voice in her head was not really her, it was someone using the Valkyrie link and there was only one person that sounded exactly like her.

'ARIN!' Tamsin thought out pulling the sheets off of her.

There was no response.

'ARIN! Snap out of it! Where are you?!' Tamsin then cursed since she managed to slip off all her clothes during the night and had to redress quickly.

'Ariiiiiiiiiiin! Freaking reply NOW!' Tamsin already knew without a reply that Arin, her most trusted twin sister was bedding with Bo.

Feelings of hurt and betrayal brewed inside of her.

Arin finally responded and sleeply replied, 'Sis. Sooooo tired.'

Tamsin pulled on her pants, dove into a shirt and grabbed 2 daggers and walked purposefully to Arin's room and sure enough, she wasn't there.

She was really mad and upset now. Arin was sleeping with HER succubus. Bo was hers and hers alone. That thought was quickly dismissed when she realized that Bo was Lauren's. But why did Arin stab her in the back like this?

Bo's bed wasn't even cold from her and here was Arin bedding with Bo. Most of all, Arin was with the light, but why did she malign her? They were sisters by blood. Had their time away from one another change her where she would stoop so low like a vulture and take her Bo.

Again, Tamsin shook her head, Bo wasn't hers.

Tamsin left her room and slammed the door behind her and made her way to the gym and found the nearest punching bag and worked on it with brute force. Punches, kicks, elbows, knees were all open game.

These bags were reinforced for Valkyries, but even then Tamsin was so pissed off and strong that she pulverized them into mounds of sand and leather.

Tamsin's hands were bloodied now and she just grunted working the last of 5 punching back, "Arin you fucking traitor. You can keep that slut."

Tamsin did a spinning hook kick which sent the bag flying across the room when it broke free from the chain holding it up.

Tamsin immediately mounted it and just wailed on the bag with everything she got.

"My OWN sister! (Punch punch punch) stabbed me in the back! (punch elbow, headbutt) Ahhhhh! (head butt, punch, hammer fist). I TRUSTED HER! (Punch, elbow, elbow)."

Tamsin was so incensed that blood ran down her forehead due to the force of the head butt, her fists bloody and the problem was NOTHING was calming her down.

Betrayal was served by those close to you and this topped the list. Lauren was her best friend compared to what Arin just did.

Tamsin didn't stop until the bag broke and was reduced to a pile of sand just like the others.

'How could she do this to me?' Tamsin thought with tears streaking down her face now.

The very last person on this earth that would betray her did so without hesitation.

Tamsin couldn't take it any longer as she jolted up and quickly strode to the portal.

She wanted to face her betrayer or betrayers. Bo should have known better too and this was the last straw.

She still had no idea what she was going to do when she caught up with Arin. Beating to a pulp 6 punching bags just didn't do it for her.

It was a blur as other Valkyrie just got out of the way of the scorned Valkyrie on a war path.

Once through the portal and Tamsin didn't care, she flew to the crack shack. She stealthily made her way into through a boarded up window that was missing board.

She walked up to the bed and identified 3 women under the sheets. ALL of whom she had a beef with.

Tamsin wanted to KILL. Kill them all. They all screwed her over.

Lauren? She undermined her relationship with Bo. She slept with Bo on purpose to put a wedge in their relationship. Then Lauren pried Bo away from her when things were going so well. Effing Traitor.

Bo? She made her grovel for even an iota of her love. Treated her like nothing. That piece of crap succubus had the audacity to dismiss her feelings. Bo WAS a feeling being and she knew better. Tamsin felt like a street walker paid nothing for a deed but the fact remained that Tamsin's love was NEVER for sale. Effing traitor.

Arin? She just had to bed with her succubus to add insult to injury. Her deed hurt the worst. The very last person she expected to betray her was Arin. They were inseparable through most of their life times and no matter what, they were there for each other. Even when Tamsin was cast out of the sisterhood, Arin still talked to her over the link even though expressly forbidden. It made her exile tolerable. Effing traitor. The biggest one of them all.

Tamsin wanted to make sure Arin died like a Valkyrie and thought out to her.

'REALLY sis? 'So that's what love feels like?'' Tamsin questioned in a mocking manner over the link.

Arin's eyes batted open and as soon as she focused on her popped up in horror.

Tamsin yanked her out of the bed and slammed her on the ground in a choke hold with a dagger in hand.

Bo and Lauren were still trying to catch up with what was going on and Lauren trying to cover up and Bo rushed over to help the naked Valkyrie.

This was made a lot more complex when Bo recognized that the clothed Valkyrie looked exactly like Tamsin too. All she could do was try to split them apart.

Arin yelled over the link in pain as her life was being squeezed out of her, 'Sister, she THALLED me! I came to hurt and maybe KILL her for thinking about you! PLEASE…. PLEASE…'

Tamsin just smacked Bo and sent her flying into a wall. She would deal with her later, but right now she had to kill her sister on her last life.

'Yea fucking tell me a new one Arin!' Tamsin thought back.

'Pllllllleaaase… I was torturing her and cut her to punish her…. ..noooo…. i…' Arin could no longer think as she felt her eyes get heavy.

"FUCK YOU Arin. You betrayed me. You're my Fracking twin SISTER!" Tamsin spat back verbally.

Arin didn't resist this whole time as she thought out weakly, 'I love you. Sisters to the very end.'

Tamsin looked away getting teary eyed that she was snuffing out her own sister life but spotted Arin's cloths in a messy pile. They were all black. Valkyrie knives were everywhere …. About 8 to be exact. It came to her quickly as she immediately released Arin. Arin was going to teach Bo a lesson but ended up being a thrall.

Arin coughed and Bo got back up ready to engage with a dagger and Lauren was right behind her with a bat a little hesitant on what to do.

"SHIT. I'm sorry Arin," Tamsin caressed Arin's face and pulled her up. "I… I thought you went out of your way to sleep with Bo and hurt me on purpose."

"Thomasina. I am of your blood. I would never to that to you," Arin murmured catching her breath then hugging her sister.

Lauren spoke up first, "Oh my god. You are the legendary Valkyrie twin sisters of the light and dark. I … I just never thought to expand Tamsin's name to Thomasina."

Bo then barked as Tamsin stood up to face them, "What the HECK is going on here?! You mean I've been talking to … umm ARIN this whole time?" Bo pointed sharply to Arin.

Arin was grabbing her clothes donning them on as fast as possible.

Tamsin just coolly responded, "Yep. After our 'TALK'. I did a bait and switch on you. Didn't feel like talking to a lousy, cheating, back stabbing, whore. But THIS takes the cake. Did you freaking thrall my sister and screw her brains out?"

Bo immediately went defensive since she knew she was guilty as charged. She kept her fighting stance keeping Lauren behind her and stated, "Look Tamsin. She got really upset and I needed to calm her down."

Tamsin just yelled getting enraged with Arin gathering some of her many knives, "OK. Do you think I was born yesterday?! So you thralled her and got her to calm down, but THEN you decided to mount her and plunder her temple! HOW MANY TIMES did she touch the stars?!"

Bo's mouth moved, but nothing came out.

Arin meekly replied, "5 times."

Lauren couldn't believe what she was hearing. Bo was red faced which meant what Arin stated was true. It wasn't a dream after all. Bo made love to Arin while she was probably under a thrall as well. She still however held her ground with her bat at the ready.

Arin was now ready to engage as well flanking Bo and Lauren.

"FIVE Effing TIMES! Getting your fucking FILL you SLUT! You can't HAVE me but you RAPED my sister instead. FIVE TIMES. FIVE! You might as have well done it to me!" Tamsin screeched.

"I thought it was YOU!" Bo defended but was losing her argument quickly. "Arin never identified herself."

Arin just chimed in, "BECAUSE Bo, your heart would yearn for Tamsin even more if you knew. You would just end up hurting her MORE."

"Oh boy," Lauren stated glancing at Bo, "Annnnnd we're back. Bo you're bonded to Tamsin. So that means that you where thinking about Tamsin when we were …"

Bo just glanced Lauren and cut it, "Let's talk about this later all right?"

'Oh boy,' Arin thought, 'This is good.'

Tamsin just growled, "Shut up doc. You're next on my list to kill. You were ALWAYS second place to me 'cus once Bo went Valkryie, she didn't want anyone else but me."

"That's some big rhyme coming from a Valkyrie that has done nothing but evil deeds throughout her lifetimes. Besides, she's still mine. And try this rhyme. You're more than just a boozer, maybe just face the facts that you're just a ….." Lauren smoothly jeered.

"Enough!" Bo shouted. "Let's just all calm down and talk this through."

Kenzi then ran in and skid to a halt with her samurai sword ready to go, but no sooner assessed the situation and knew it was bad. She woke up due to all the yelling and scuffling.

"Bo bear," Kenzi asked unsure darting her glace to Bo and Lauren then Arin and Tamsin. "Emmm are we playing a game here with skins verses shirts?"

Lauren just glimpsed down and remembered that she didn't get dressed with her face turning beet red.

"Yup," Tamsin stated with a click then directed her attention once more to Bo, "Bo, we were a couple and you cheated on me, but I did nothing because I loved you. You then patronized me that I was imaging I loved you, but I did nothing because I loved you. You told me that you loved me, but not in the way you loved everyone else. I DID NOTHING because I loved you. You crushed my heart shattering it to a million pieces and breaking my spirit, but I did NOTHING AGAIN. Not because I was a coward, but because I LOVED YOU."

"Tamsin Please," Bo pleaded since knew she was in deep trouble at where this was going.

Tamsin crept forward in her fighting stance drawing both of her daggers.

'Arin get ready'

'No Tamsin. Bo doesn't deserve to die. She's just messed up in the head. PLEASE.'

'WTF? Arin do you have my back or did you spend too much time with this succubus that defiled you and made you lick her boots.'

'Yes I have your back. Be careful, Bo is powerful and don't hurt Kenzi.'

'Yup, you got the doctor? I got Bo.'

'Yes. I'll make sure she dies a slow agonizing death.'

'THAT'S my girl!'

"TAMSIN! ARIN!" Bo stated with her eye going blue, "Don't do this. I still care for you."

"HOLY CRAP!" Kenzi yelled, "Gotta 245 (police code for assault w/ deadly weapon) in progress! EVERYONE chill!"

Tamsin didn't back down, "NOW you ruin my SISTER of the LIGHT! You NEVER thrall a Valkyrie but I put up with it … and YOU know why! But my SISTER Bo! You can do what you will to me, but for this…."

Kenzi approached to get in between but Tamsin used the flat of her blade to stop her from doing so.

"Taaaaasiiiin!" Bo growled in a slightly lower octave voice with her eye now flicking blue. "Last chance STOP this or else."

Tamsin just held and aloof smirk, "You and your slut doctor are going to DIE!"

Tamsin charged Bo and Bo got out of the way and redirected her going full glowing red.

Kenzi knew Bo was going to try to fillet her daughter so she charged and hugged Tamsin to push her out of the way and act as a human shield. Bo wouldn't hurt her.

Arin charged Lauren and Lauren swung her bat at full force. Arin ducked it however and slammed Lauren to the ground taking her down.

"AHHHHHH!" Lauren shrieked as Arin slammed her bat hand into the ground breaking bones. Lauren had no choice but to let it go.

Arin followed up with a punch to Lauren's face with her brass knuckles knife combo. Blood shot out of Lauren's nose and Arin was about to cut one of her arteries so she could die slowly, but was then slammed brutally into a wall by and bright red energy force. Before she knew it she was pinned with her back to the wall hurting all over.

Lauren fell unconscious.

"Noooooo Arin!" Tamsin yelled as a sadistic smile crept on Bo's face. Bo never looked at Arin and kept her eyes dead focused on Tamsin. Bo was floating now, as red glowed and emanated from her entire body.

Kenzi just held Tamsin back. She knew Bo in her red state was unstoppable. She felt Tamsin's tears hit her shoulder.

"Don't hurt her Bo!" Tamsin screamed in pain.

Bo just pushed out more power as Arin yelled in ultimate agony. Bo finally stated in a low octave voice, "No one EVER defies me. I RULE over life and death. I say who lives and who dies. How DARE you hurt my family Thomasina! Her life is therefore forfeit due to your insolence!"

"Nooooooooooooo," Tamsin yelled with streams of tear streaking down her face, "Please, not her. TAKE ME!"

"NO!" Bo commanded, "You must LEARN and PAY for your mistakes and SINS against humanity and Fae kind. But most of all your indiscretions against ME! You will LIVE and I will take her useless life."

"NO!" Tamsin and Kenzi yelled in unison.

"Please NO. I'll do ANYTHING you want," Tamsin begging once more out of desperation clapping her hand together in a sort of prayer. She knew that even if Kenzi wasn't there, they were all dead.

Bo started to pull Arin's chi and she fell limp. "You have 10 seconds to give me your fealty and that MIGHT be enough to SAVE your precious sister. If you do, whether she lives or dies you will be MINE. FOREVER!"

"I'll do it!" Tamsin blurted out not knowing what other option she had.

"CRAP Bo Bear!" Kenzi shouted turning around, "Valkyries only serve Freya! She can't!"

"I DON'T CARE! 5 seconds!" Bo pulled chi faster.

Tamsin was a mess and knew that once she did this, Bo would OWN her heart and soul. There was no way to repair her dignity or life.

She would be nothing more than Bo's slave and Freya, whether she liked it or not would probably comply to not enrage Hades.

Tamsin stepped forward but as she was about to kneel before Bo, she heard Arin hoarse and weak through the link, 'Don't do it sister. Let me die. Then avenge …...'

"No!" Tamsin face contorted in pain knowing that Arin could already be dead. She never felt so weak before and cried out for her sister. Tears followed as the one she loved was twisting a knife further into her heart. She was already broken, but this would seal her fate.

"DO IT!" Bo ordered smiling maniacally.

Tamsin ran through her choices in a split second.

Engage Bo and probably die but she would go out with her sister a warrior.

Run away but not only did she hate running away, Arin would still be dead and she would be labeled just a coward. How would she be able to face Freya or any of her sisterhood again?

Swear fealty to Bo. Granted it would be to her god complex, but it would also bind her to Bo, the succubus as well. Tamsin NEVER served anyone. She was too proud. Too independent and when she did show her heart to Bo, she crushed it without an iota thought.

But her sister? She needed her now more than ever especially after she was crushed by Bo.

It left her one choice to save face.

Go out with a bang and FIGHT.

But before she knew it her heart took over and her knees hit the ground sharply saying things as if she had no control over herself, "I, Thomasina, Dark Valkyrie promise my soul that I will spend the remainder of my lifetime faithful in service and devotion to you Bo Dennis, goddess and daughter of Hades. I will never cause you harm and will observe my homage to you utterly and completely against all enemies in good faith and without deceit. I am yours to command until my final breath."

Tamsin looked down at the floor and slumped back onto her heels hoping that Bo would keep her end of the bargain. At this point, Bo really didn't need to. She was now Bo's and her fate was sealed regardless.

"SHIT!" Kenzi stated scampering over to Bo falling into her arms passed out.

Tamsin jumped up like a cat and ran to her sister who was lying flat on the floor. At least Bo was nice enough to let her down gently before she passed out.

Tamsin quickly accessed her sister.

Arin wasn't breathing.

Kenzi just slapped Bo lightly on the face and kissed her to try to at least get her conscious by pulling chi. For some odd reason, Kenzi mused, deep down, Bo knew what she just did and it was her choice now to revive but revive and live with HER OWN consequences?

Kenzi was also aware that Tamsin was in shambles as she yelled for her sister to wake up shaking her.

This was messed up to the nth degree, Kenzi noted with a tear running down her face. Everyone was ironically killing each other with love. How did it ever get to this? With all this, even with the best outcome, could she still call Bo her sister?

"No… No… PLEASE Arin! PLEASE open your eyes!" Tamsin begged in tears starting mouth to mouth out of sheer desperation.

For Tamsin the world stood still. Nothing mattered at this moment but Arin. Bo was DEAD to Tamsin now.
