Leave Out All The Rest

Chapter One: Say It Right

"Spencer! Spencer come downstairs for a moment!" Paula Carlin yelled from the bottom of the stairs, with a loud groan and sigh being heard Paula knew her daughter was on her way.

"What is it mom, Chelsea is going to be here any moment and I'm not even ready yet." The annoyed teen spoke

"Sorry," her mother replied sarcastically while rolling her eyes, "but I just assumed that you'd want to know that I just got off the phone with your cousin who was curious to see if you were still interested in learning everything there is to know about UCLA."

The loud and excited scream caused a smile to form on the older Carlin's face as she watched her daughter jump around.

"Serously? Please don't tell me you're kidding." Asked the younger blonde. "No Spencer, I'm not and I already told her yes so don't make any plans for"

"Oh my God!" the screaming continued with some rambling thrown in, "I haven't seen here in months, this summer is going to be so amazing, I can't believe it, we can go to the beach, check out the campus, do some shopping, I just can't believe," the young girl stopped mid sentence and turned to her mother, "wait a minute. Mom I thought Dawn wasn't going to be around this summer."

"Well honey," Paula paused wondering just how to break the news, "as you know next week is the family trip back to Ohio to visit your grandmother, aunts and uncles, and, well, instead of coming back home with us you're going to Cleveland, for the summer."

"What?!" screamed Spencer

"Cleveland?!"

"Please calm down, you're making a scene and yes, Cleveland."

"Cleveland?" an angry whisper replaces a shocked scream

"I told you last week I needed to go look over one of the slayer headquarters this summer."

"Yeah, you did, but I just thought you were talking about one of the slayer centrals OUTside of the country. I thought maybe you were thinking about checking on your double in Italy or visiting Kennedy and Willow in Brazil or maybe even checking on the construction Xander's doing in England, him and Giles have to got be annoyed with each other by now."

"Dawnie," Buffy spoke softly trying to calm her sister down "I know Cleveland doesn't sound exciting but there is something really important there I need to go keep an eye on."

"Like what, Faith?" Spoke the brunette as she glared across the restaurant table, "I thought you said this summer was all about me and you and some sisterly bonding, not about rekindling last summer's late night hook up."

"And I meant what I said, me and you will, wait. Hook up? I told you nothing happened, what you saw was,"

"Whatever, I don't care about last summer," the younger Summers cut in "Buffy, I'm tired of coming in second to your precious slayers. All year they get your attention, you teach them and train them, and when I bring home straight A's you're busy but when they slay their first vamp it's like you want to throw them some kind of parade."

"Dawnie," the older sister spoke sympathetically, while reaching across the table to clasp her sister's hand "you know that's not true. Yes during the year I'm very busy but you know I'm never to busy for you. I am very proud of everything you do at school and this summer is really about you." Watching her sister glare, lean back in her chair, and follow all that up with an roll the slayer knew it was time to come clean, "Fine, I was trying to surprise you but you really are the reason we are going to Cleveland. I actually have been paying attention to your school work, and the straight A's in seven classes has proved how serious you are with your studies and responsibilities. Anyway, after a long long talk with Giles I finally agreed that, if you still wanted it, you could start training to be a watcher."

"What?!" a shriek from the younger Summers sister caused their table to once again become center of attention, or rather, the center of much angered looks. "Are you serious?!"

"Dawn, indoor voice please."

"Buffy" spoke an impatient but quieter Dawn.

"Yes I am, But," The slayer spoke quickly before another teenage scream could be let out "that only happens if the girl Faith picked out for you finishes her training and passes all requirements needed to slay on her own."

Pausing to process this information the former key glances back at her sister "Why wouldn't she?"

Relieved to finally have her sister back to calm and rational the older girl responded, "I don't know. Faith hasn't actually talked to me about this at all. After I talked to Giles about everything, he called Robin because a lot of the girls in Cleveland are from California, so he thought there may be someone there for you. Robin called me and said Faith has a girl that is perfect but every time I try to get more information on this perfect girl he barely has anything to tell me. All I know is that Faith has personally taken her under her wing and thinks the two of you would work well together."

"Well what does Faith tell you about her?"

"Nothing, she hasn't been returning my calls and seeing how I have an interest in one of the slayers in Cleveland and I haven't visited the school since it opened I figured it was do time I did a little look around."

"Again I have to ask, what does Faith think of that? Cleveland is basically her territory." The brunette asked curiously

"Nothing, she hasn't returned my calls so how could I tell her. I brought up my idea to Robin and he agrees, plus he thinks it will boost the moral of all the girls stuck there over the summer."

"So does that mean I'm going to be stuck there as well over the summer learning to be all watchery while general Buffy makes sure the girls are in tip top shape?" A less than excited Dawn asked

"No, I told you this summer is about you and fun. Giles gave me a list of books you have to look over while in Cleveland and I do have actual business to look over while there but there is fun for you to be had."

"Oh yeah books are always exciting." Dawn rolled her eyes

"Actually not so much books, more so our favorite cousin who has been rather curious about UCLA." Buffy smile while leaning back in her chair watching the realization express itself on her sister's face.

"Are you fucking kidding me?!"

"No Faith I'm being quite serious."

In the large office of Robin Wood an angry brunette is huffing and puffing as she paces back and forth. "Faith calm down this isn't the end of the world, it's one visit." The pacing immediately stops and the ex rogue sends a glare towards her ex-lover "Yeah it's just one visit from general Buffy. This is my school," the brunette smiles sheepishly when the man lets out a cough "I mean our school. The minute she walks in here it is all going to be about her and what she wants to change about this place."

Letting out a sigh, Robin stands and walks over to the brunette slayer to try to find a way to calm down. "Listen Faith, I know you and Buffy are not the best of friends but everyone knows when she came up with the idea for these schools and picked who was going to be in charge she put trust into those people. There has not been one instance yet where she has visited an HQ and changed it into what she wanted."

Letting out a snort the brunette obviously looked to disagree "You know the difference Roby, everyone else is part of her precious Scooby's and they could do no wrong. The minute she steps a foot in here everything will change."

Making a sigh of his own, Robin was quickly seeing less amusement in this conversation and was ready to get to what was really going on. "What's the real problem Faith? We both know having Buffy around is not going to be so horrible, hell the last time you guys were around each other"

"That was different." Faith cut in "This isn't about B and me."

"No it isn't," The ex principle said finally getting what was going on "and do not try to play the she is the good slayer and the girls are going to fall all over her thing because we both know it's not that either. Yes Buffy being here is going to be big news but you know that only means the girls will be on their best behavior."

Walking over to the window that over looked the outside training grounds Faith sighed to herself. "Not every girl."

Finally seeing the problem completely a side smile spread on Robin's face as he stared over at the concerned slayer, "Ah, I almost forgot,"

"ASHLEY!"

Five slayers jumped when the name was suddenly screamed, breaking all silence they had while studying. Instead of going back to their work the girls filed out of the dorm room and into the hall to watch an angry red head begin to pound on one of the other dorm doors. "Ashley, open this fucking door!"

Watching on in amusement the others stared at the obviously pissed slayer and then tried to contain their laughter when they realized that she just noticed the door was actually unlocked. Stepping back from the door for a moment the red head looked as though she was trying to calm herself down as much as possible. After letting out a few breathes the other slayers watched as the unknown slayer pushed open the door in front of her and march in, excitement went through the girls watching on in the hall as they realized the door was left ajar. Scampering over the eavesdropping slayers saw the red head yelling at a brunette as she lay on her bed.

"Who do you think you are Ashley? How could you do this to me?!"

The brunette seemed confused and annoyed tat being bothered. As for the red head she just kept on staring waiting for a reply but when the brunette just kept staring back the red head just lost it. "ANSWER ME DAMN IT!!" she screamed while throwing her hands in the air.

Still looking confused the brunette held up her finger in a jester that could be taken as 'hold on' and leaned to take out what looked like her ipod. Hitting one of the buttons the Ashley then went and moved her hair back showing the headphones she had on. Realizing that everything she had just said had been tuned out by music both enraged the red headed slayer and amused the audience of slayers watching on. Making no effort to put her stuff away quickly the brunette slowing wrapped the cord of her headphones around the ipod, put it on a pillow next to her, and crossed her arms across her chest as she leaned back to look over at the irate girl next to her. "What?"

"What?" the red head replied in an icy tone "All you have to say is what?"

Rolling her own eyes and throwing a glare at the pissed off slayer, Ashley restates her question. "What do you want?"

Nostrils' flaring the red head's face begins to match her hair. "What do I want? I want to know what you were doing with my roommate last night."

Smirking to herself the brunette slayer had no hesitation in answering, "Giving her a goodbye fuck. You know, like the one I gave you last week."

Whipping her hand out to smack the smirk off Ashley's face her hand gets stopped mid air and her body gets slammed into the nearest wall. "Don't even think about it princess."

Holding back tears the red head tries to push the brunette off of her. "I thought you liked me."

"I thought you knew better." Came the harsh reply "I told you what I wanted and that's all it was. Now get the fuck out of my room before I stop being so nice."

Walking toward the door the red head finally notices the onlookers as they try to quickly disperse. As eyes follow her as she slowly walks back down the hall. Some looks grace her with sympathy but most hold pity. Ashley Davies isn't the type to change, for anyone.
