Xander walked into the library smiling, as everything was looking good Buffy was back and his and Cordy's relationship was still going steady. He froze at the scene that greeted him, Buffy was standing in the middle of the library flanked by Willow and Oz. Buffy's expression was one of pure hate and loathing and Willow's and Oz's were identical masks of emotionlessness, Xander felt his smile fall off his lips. "What's wrong Buff" he stuttered, hoping that she had not found out his secret. "You son of a Bitch, you lied to me, I killed my soul mate because of you, why didn't you tell me that Will was trying to do?" she screeched, Xander opened his mouth to reply but Buffy interrupted "Never mind I don't care what have to say, nothing you could ever say would be worth listening to" and before Xander could say anything she lunged at him and threw him into a wall, then set upon him with her fists and feet. All this time Will and Oz watched with the same emotionless faces as before. Giles and Cordelia walked into the room as Buffy continued to beat him up, upon seeing this Giles when to stop Buffy but was stopped by Cordelia, who's face had fallen into an emotionless mask, caught him, and murmured "let her, Buffy needs to get this out of her system." Xander who was almost unconscious heard this and gave up, everyone he cared about hated him, and with that thought he let go and fell into unconscious. "No" Giles stated as he pulled himself from her grasp "Buffy stop, why would you do this to Xander. He is you friend, now move I must check if he is ok" he called to Buffy who at the sound of his voice stopped and jumped back to Willow and Oz who moved to flank her again, out of the corner of his eye Giles saw Cordelia slide over to Buffy and also flank her. Giles was slightly surprised by that action, but decided to ignore it and deal with the problem at hand.

….

Xander lay in a hospital bed, comatose, as he had been for the last couple of days. Buffy was still to mad to even bother to go and see him. Willow, Oz and Cordelia had all done the same, Giles was the only one who had sat beside the boys' bed.

….

Xander eyes snapped open with a small cry of fear, Giles who had been sleeping by his bed jerked awake, "Xander? Oh…uhmm… how do you feel" Giles muttered still half asleep. "Oh…..good… I guess, forgetting the fact I had crap beaten out of me" Xander replied awkwardly, Giles nodded, before waiting for Xander to continue, when he didn't Giles voiced an idea "I think it would be safer for you if you left Sunnydale, because Buffy and the others still seem to be in a violent mood." At this Xander's head drooped and he nodded in agreement, Giles looked up at Xander when he noticed the lack of noise he was making and saw the boys' lip trembling as Xander fought against the sobs trying to break free, but he could not hold back the tears which were slipping down his cheek. Giles began to take back what he had said when Xander interrupted him "I think your right, it would be safer for me if I did leave. Can I get my stuff and write a letter first?" Xander's voice was shaking with unshed tears but he still managed to sound strong. "Of course, when do you think you can start getting ready?" Giles was shocked, he thought he would have to argue with Xander. But here Xander was getting ready to call the nurse, "as soon as they say I can leave".

….

It turned out that Xander could leave that day, so in less than twenty minutes Xander and Giles were walking out the door of the hospital and into Giles car, once Xander was packed and the letters sealed into their envelopes, (Xander had written one for almost everyone) Giles drove him to the bus stop, where they waited for his bus. "So where are you going?" Giles asked quietly, Xander smiled slightly and replied "I think, I'll go to LA, cause I've always wanted to go there, plus I've got an uncle there who will give me a place to stay." After ten minutes the bus arrived and Xander stood up to go, "Xander, before you go have this letter, because I fear that we may not get to see one another for quite some time, It has my phone number, so if you ever feel the need to call you can." A sad smile spread across Xander lips before he hugged Giles and turned to go "see ya, G-man" he called, then as he walked away Giles called out "Good bye, Xander"

….

Willow, Buffy, Oz and Cordelia sat in the library talking about the latest fashion, music and sport when Giles stomped in, a look of sadness mixed with a scowl on his face, when he saw them the sadness faded and the scowl deepened. The others saw Willow stiffen and turned to look, at Giles, who was now full on glaring at them. "What's up Giles, you seen kind of angry? Is there a new big bad we have to fight?" Buffy chirped, which only made Giles glare harden. "Xander woke up from his coma, this morning" was all that Giles said and watched as Buffy Jumped up with an evil grin "good I need to finish what I started" she pronounced, causing an uneasy look to pass among the other three. "Oh, he's not there anymore" Giles stated, Willow jumped up and cried "Oh God, what have I done, where is he? I need to apologize or beg for forgiveness or….or…"Willow bust out in tears of horror, guilt and sadness, that were so violent that her whole body shook with them, Oz had a similar expression of horror and guilt crossed his face before he jumped up and cradled his girlfriend in his arms, rocking backwards and forwards making soothing noises. Whereas Cordelia just sat there to shocked to move, tears streaming down her face and sobs raking her body. Buffy and Giles stood among the confusion, Buffy had anger and confusion on her face whereas Giles just had shock. "He's gone, Willow, and he's probably not coming back" he murmured. At this Willow head shot up "Where is he? Please tell me, I need to see him, I need to." She cried and the intensity of her tears increased. Giles sighed and pulled the envelops out of his pocket and handed one to Willow, Cordelia, Oz and Buffy. Well the others seemed kind of thick and when opened had many pages Buffy's only had one page and it was not even filled, Buffy looked as the others read theirs with a crazed hope of finding out where he had gone. Sighing Buffy looked down at hers and read

Dear Buffy
I would say that I am sorry to leave, but since you beat me up I guess that I'm not, sure I'll miss everyone but I think that it would be safer for me to stay away from you guy. Oh and Buffy if I had told you about the soul spell we would all be in hell or dead, and you know I'm right. Which is why you were so violent, and I'm sorry for the pain I put you through, even if you're not sorry for what you did to me. It was nice to know you, and I hope that someday you might regret what you have done and maybe we can be friends again, but knowing you that's probably not going to happen for a long, long time.
Xander

A small sob escaped her, and the room froze, everyone looked at her in shock and waited. "I'm going patrolling, Giles" she growled, trying to hold back the sudden guilt. With that she sped out the door and into the night, a small 'oh' rang around the room and everyone then turned to Willow instead, who was looking at the ground with sudden interest "Willow" Giles questioned "what did you do?"
