Author Notes: I leave unsigned reviews enabled because I don't mind the occasional helpful flamer that wants to remain anonymous, and anyone flaming for the sack of flaming can be deleted. However, when I receive a well thought out review from someone who's unsigned, and I can't reply back, I think about disabling it. Since I don't want to have an Author note the same size as my chapter, I'll answer a few things brought up by him and others.

1) Xander is just as human as he was during the series, and Harry is just a wizard. He isn't immortal, and he knows that it doesn't take a wizard of great power to kill him. If Xander wanted to, he could kill Harry. He'd have to do it in a very Slytherin way, but it isn't out of the question. Harry wasn't terrified of Xander, but he knew Xander could be a threat if he wanted to.

2) Harry's vampire's do not turn to dust when killed. In fact, I don't think many vampire's in myth do. Harry doesn't work with vampire's every day, and he isn't omniscient and the writing is from his point of view. He didn't connect the guys being dusted with vampires, because vampire's don't get dusted in his world, nor do they gang up on women in the streets. His thinking process is also not instant. If he had more time he may have come to the conclusion, but he did not.

Another thing I want to mention is that my biggest pet peeve in Harry Crossovers is one character dominating the others. In other Harry Crossovers, I see Harry being able to kill a dozen vampires with one spell, leaving Buffy and everyone else virtually useless in a battle of greater scales. Demons will be resistant to Harry's magic here, some more than others, and some with different strengths against Harry's magic. It creates a challenge for Harry in battle. It also means he can't go out whenever a threat appears and wipe them out in a minute.

Harry will be battle ready, smart, and powerful in this story. He can also make mistakes, be at a disadvantage, and be stupid in certain situations.

Well, this author note was already way longer than I wanted it to be, and I'm sorry if I bored anyone with it. I hate leaving review questions on answered.

On with the chapter!

Chapter Three

A Plan

After the teenagers had all the left the library, the two watchers sat in silence for a while. The silence however, was shortly interrupted by the younger watcher. "We must tell the council immediately. From what the boy's told us, he could become a terrible power. The council must know of him." Wesley said, getting up from his chair and making his way to the phone. Although Giles wanted to stop him, there was really nothing he could do. He was on strict orders from the council to let Wesley take the lead. Any argument from him would end up with him being sent to England. He settled for reasoning with Wesley.

"Wesley." Giles said shortly and was glad to see Wesley stop in mid step to listen. "We both know the dangers of this Mayor situation. If the council knew about Harry, there's no telling if there'll kill him in fear, kidnap him, or any other one of the infinite possible actions." Giles paused, watching as the truth of the situation became clear to the young watcher. "I do agree that the council needs to know" Giles lied smoothly, to keep Wesley calm. "but can we wait until after the mayor is taken care of? What's one powerful wizard going to do if we have a real, full sized demon to worry about? If anything he could help." Giles watched as Wesley made his way back to his seat, sitting down tiredly. Giles was glad to see this small improvement in Wesley's thinking. Only weeks earlier, Wesley wouldn't have hesitated to use the phone to call the Council, even with Giles' argument.

"As soon as we defeat the Mayor, I'll call them." Wesley said. Giles smiled, proudly; the first time he himself had conveniently forgotten to mention something to the council was the hardest as well. Giles thought he might actually be able to make a good Watcher out of the man. His smile diminished as realized what Wesley had said.

"If we defeat the Mayor." Giles corrected, looking down at the ancient parchment in front of him. The pages that Willow was able to tear from the books were still being deciphered. Although useful, Giles still couldn't help but cringe every time he thought of the priceless book; pages hastily and crudely being ripped from its bindings. From what he could gather about this transformation that the Mayor would be going through, not many of them had a chance of living through it.

It had been nearly a week since I had started reliving my school days, and it was just as bad as I thought it would be. Starting day one, I had begun skipping most of my classes, but taking advice from Willow, I went to a few; enough where they wouldn't try to send me back to England because of my failing grades.

I was surprised when Willow's mother barely batted an eyelash at my sudden appearance. She seemed to be excited to have a foreign exchange student in her home, even if we hadn't spoken more than two sentences to each other.

I had picked the worst time in the school year to appear as an exchange student, and that was prom. Prom was only a week away when I first started at the school, and it appeared that the teenage girls couldn't get enough of my accent. If I was my father, I may have taken advantage of it; but as it was, I knew I'd barely be able to stand spending the night with any of them. I was surprisingly able to politely decline the many offers without making any of them cry. Though I was sure one of them got pretty close.

It was the day of the prom and as school already ended for the day, I was able to avoid getting myself a date. Although I spoke with Willow in the morning and night and even answered many of her questions to thank her for allowing me to stay at her house, I hadn't done much more talking with Buffy or anyone else I had met when arriving here. I spent most of my time in the library, researching the history of demons. Almost everything about my worlds history that I could recall was the same in this world, except for the underground world of demons. To a normal Muggle or someone who wasn't aware of demons, our two worlds would probably appear identical. It seemed the only difference between the two worlds was magical or paranormal in nature.

When I wasn't in the library researching, I was patrolling solo. Buffy usually patrolled with Angel, but there were multiple cemeteries in the town, and all of them were just as dangerous as each other due to the hellmouth. Willow had explained to me what the hellmouth was when I asked if this world was as dangerous as it appeared. From what I knew, most towns were relatively safe, and it was only Sunnydale, and some towns around it that housed the many demons of the world. I had a lot of practice battling wizards and witches, but battling demons was a whole knew experience. They were stronger and faster than anyone I had dueled with before. Not only that, but distance was a big thing. In a duel, distance was never a problem, for anyone I dueled with would keep their distance from me, knowing that I was very fast in a duel and decent at hand to hand combat. If I wasn't careful against demons however, I could easily get surrounded, lose my wand, and be helpless. My competence in combat could not match up with their strength and speed. There were only a few spells in my arsenal with much of an effect against Vampires as well, and I was always experimenting each night for some more useful spells that I could remember. Without any place where I could learn more magic, I was either going to have to get creative, or use my limited knowledge of spell creation to try to create some unique spells.

As I made my way into the Library for my self scheduled research before patrol period I noticed that the group was gathered together. I walked in just as Buffy was preparing to leave. "What going on?" I asked, following her out, curious to what was making her look so determined.

"Hellhound's attacking prom." She replied. I started to walk a little faster in enthusiasm along side her.

"Can I come?" I asked in excitement. Although her and I hadn't talked much since she broke of my leg, which I was able to mend back together with a magical potion; I figured we could bond over a little demon slayer. She shook her head in dismissal,

"No. Go to the prom with the others." I laughed at her harshly. She glared at me from the corner of her eye as we made our way outside of the school.

"I'm not you Buffy." I said seriously, watching as she raised her eyebrow at the obvious statement. I explained further, "You may think you're doing me a favor, keeping me out of the fight. But I belong in the fight, just like you." I said. She stopped outside the school and turned to me with her arms crossed. I didn't stop talking however, "Unlike you however, I admit that to myself. You may have convinced yourself that as a teenage girl prom would make you happy; but I think life gave you a lemon with this hellhound. You can kill this thing, save prom, and never have to admit to yourself that it's what you'd rather be doing anyway."

"You're wrong." She said angrily. I suddenly realized I was a minute away from having another broken leg.

"Maybe" I replied, trying to keep my leg intact, "But I don't think so." I knew I just talked myself out of accompanying her, but her constant whining at being in danger was tiresome. I had only been here a week with limited contact with her and I spotted that she was very similar to me in that way. I knew that if she ever won her fight against evil like I did, she would be in the exact same position as me a year after. I could only imagine how annoying I was during my school years if I resembled her in anyway.

"You're not coming." She commanded with no room for me to argue as she tried to ignore what I just said. "But, you can stay at the school. If I don't find them in time, it'll be up to you." I sighed in disappointment but nodded in agreement. Just the possibility of getting into a fight with a hellhound just wasn't as thrilling as knowing I'd be able to. Having a last line of defense wasn't bad thinking however, so I grudgingly allowed her to lead.

Unfortunately this meant that I was going to have to do the unthinkable and get a tux in order to not look out of place at the school tonight.

It was hours later and I was pacing in front of the school for what felt like at least an hour in restlessness. I had transformed my clothes into a shabby looking tux since I didn't really feel like spending the small allowance money Willow's mum had given me when she found out I was broke for something as pointless as a tux just to appear like I belonged there. I had taken a liking to summoning demons wallets and purses before killing them. I figured the money would just disappear into dust if I didn't steal them. I was able to rationalize that I was just doing the economy a favor, keeping the money from being destroyed needlessly.

I already had a couple run ins with a few people that I had told I wasn't coming to the prom earlier in the week as I waited in front of the school. They all gave me dirty looks at seeing me as well; I was just glad that I'd only be staying at the school for a month at the most before everyone would leave for the summer.

I was just about ready to call it quits, not knowing if Buffy would even care to let me know that it was all taken care of when I heard a loud growling sound in the distance, causing a bright and cheerful smile to appear on my face. An hour of boredom and angry scowls from girls I had rejected would be worth it; at least I hoped so. I had a dozen or so spells filed into my mind to be used during this confrontation. I drew my wand as I saw two shadows make their way out of the darkness, running in my direction at what looked like full speed. They definitely looked demonic. With hard grey and black skin and a vampiric looking face, there was no doubt in my mind that they needed killing. They were running on four legs, which made sense, as Buffy had called them hounds earlier. However, their was two of them, and I was only one wizard. I looked up from their approach and noticed Buffy running as fast as she could behind them, but not fast enough. I readied my wand and took aim. "Depulso" I said calmly, watching as a burst of bright white light nailed the hellhound on the left, who just watched it come at him; too stupid to dodge. The hound was flung up in the air, and I watched as Buffy had to swerve out of the way of the flying beast. She gave me a dirty look in response.

"You're welcome." I said quietly to myself as I watched Buffy go after the landed beast before facing the last one. This one didn't seem to be nearly as stupid. It looked at my wand in confusion, but it seemed to already know that my wand was a danger to its life. It began its approach again, more hesitant than before "Duno" I said, giving my wand a slight jab. A dark grey beam flashed across the room, but the beast dodged out of its way clumsy, landing on its side. Seeing as the creature was fast enough to dodge my spells, and was slowly lessoning the distance between us, I settled for slowing it down. I moved my wand in a small circle multiple times, releasing my intent at the end of the movement each time. The spell's name was long enough that if I wanted to cast it multiple times vocally, it wouldn't be nearly as effective or quick. The Impediment Curse was good in a one on one fight. If connected, the opponent would be virtually useless. Unfortunately, the counter was easy enough and most wizards could cast it on themselves after only a moment of being hit. In a duel of multiple opponents, they'd just counter each other.

The Hellhound, aware of my tricks, dodged the first cleanly, but fell on his face dodging the second, and the third nailed him in the leg. I watched as his attempt to get up was slowed down. However, the Hellhound seemed to have some talent in limiting the effects of magic, for it wasn't nearly slow enough. I was in a slightly rough spot. Most of the destructive spells I knew to use in this situation were just what the name described them as; destructive. If I wanted everyone in the prom to hear, come out and see man sized holes in the ground, I'd use them, but for now I needed to find something quiet yet deadly. It immediately clicked in my head. It was one of my favorite spells, even if I was never able to use it as an Auror due to it technically being dark magic. "Sectumsempra" I whispered, watching as the slowed Hound tried to doge. It wasn't yet used to it's slowed down movements and failed to movement out of the way in time. A much shallower than usual cut appeared on the top of the beasts Beast's skull from where the spell connected, but it seemed to be deep enough, for the Hellhound fell to the ground, dead.

I looked up as a dirty Buffy walked into view. She looked down at the beast. "You made a mess." she complained, watching the blood from the demons head puddle itself on to the ground. She lowered herself over it to start dragging it away from view.

"Wait" I said, waving my wand down at the beast, watching it disappear from few. She looked at me in shock.

"Next time I have to hide a body, I'm calling you." She said tiredly. I waved my wand at her next and watched the dirt, grime, and blood disappear from her. She looked down at herself, and back up at me with a smile, before frowning.

"Why?" She asked. I shrugged back at her.

"Enjoy the normal life while you can." I said, gesturing to the school before walking away, the adrenaline running through me telling my body and brain that another confrontation was what I needed. I turned around as I heard something behind me. Buffy was trailing me. I raised my eyebrow in question and she just shrugged.

"I didn't have a date anyway." She explained.

"Angel?" I asked. It had been a week since I saw them together, but they had seemed cozy enough. She looked at me in surprise before realizing something.

"Oh right, you weren't there when I told everyone. Angel and I agreed that it wouldn't work out." From the sad look in her expression, I wondered if that was the full truth or not, but I shrugged.

"There's nothing like beating up a few vampire's as emotional release." I commented, my way of asking her to join in.

"Alright, but if you hit me with your stick, they'll be nothing left of you." Buffy said. I couldn't help myself but to respond.

"I won't touch you with my stick if you don't want me to." I said jokingly. Buffy however must have seen my innuendo coming a mile away because she just huffed to herself before walking past me, into the direction of the first graveyard of the night. I jogged for awhile to catch up with her. "So what's with the mayor?" I asked. I had asked Willow earlier and received a couple answers, but she had gone off topic almost immediately and we somehow found ourselves talking about my magic again. Buffy shrugged.

"He plans on turning himself in a demon during our graduation." Buffy explained. I nodded, already knowing this.

"Why don't we just kill him now?" I asked. When I asked Willow this question, she seemed to remember that my magic could kill and it brought a torrent of questions out of her. By the time I had answered them all, I had forgotten what we were talking about.

"He's indestructible until he ascends into whatever he's looking to become." Buffy said, looking to her left and right for any sign of movement in the eerily quiet graveyard.

"Is he immune to magic?" I asked, trying to think of ways to trap him for good. She stopped her patrolling to look at me, seeing that I was serious with trying to help.

"I don't think you can kill him with magic either." I shook my head at her.

"Not kill" I said, "Trap. That potion I made to heal my leg isn't the only one I can make. There's one potion, a lot more complicated that puts someone into such a deep sleep that most will believe him dead." Buffy looked at my questionable, wondering why I wanted to put him to sleep. I explained. "It's a permanent sleep until an antidote can be made." I said, watching as understanding lit up her eyes.

"You are the only one who knows the recipes and has the magic to use them." Buffy said, coming to my way of thinking. Willow had asked me to help her create a potion, so I instructed her step by step to create a Calming Draught. She performed it perfectly, but the potion wasn't anything but a gooey mess upon completion. I just shrugged at her, saying that magic was probably involved in the process without the brewer's knowledge. She pouted that whole night about it, but still must have told everyone else what she'd learned.

"The only problem would be finding a way to give it to him." I said, thinking. Buffy leaned up against the mausoleum next to me in thought as well.

"The Mayor is indestructible, but he isn't strong or powerful except in magic's." Buffy observed

"And if he's indestructible due to magic, there's no telling if the potion will even do anything." I said in thought, "If we force it on him, but it doesn't do anything, we'll just have one pissed off mayor with a police force and deadly magic."

"We'd have to have him take it without realizing it." Buffy concluded. My body sagged against the mausoleum as a plan reached my head.

"I know how to do it." I said solemnly, "But it isn't very ethical."

"How?" Buffy asked, coming to alert.

"The potion looks, smells, and tastes exactly like water if done properly. All we need to do is have someone slip the potion into his drink at work. If it doesn't do anything, he'll never know." I said, trying to be convincing.

"How would we get someone to slip him the potion? The only one who would him something to drink would be his secretary. Anyone else and he'd be suspicious." Buffy asked. I gave a sad smile.

"That's where the ethical part comes in." I said, thinking about another unforgivable that I was going to have to cast.

It was the next day that I was finally able to convince Buffy that putting one person under mind control was a needed evil in the situation and promised that the spell wouldn't have any lasting effects. I didn't mention the memory charm that I'd have to hit with her afterwards. I made the potion the night before. It was a surprisingly quick potion to make for such powerful results. We were both standing outside of the Mayor's building disillusioned. Buffy didn't like the feeling of it and seemed to jump every time someone came close to her, as if expecting a fight.

"Relax." I said, putting a hand on her shoulder. "The only people who will see us are people who believe in magic and are alert to their surroundings. We only have to worry about the Mayor, his Slayer, and any vampire body guards." I understood her nerves, the first magic used on me didn't leave me calm and collective either. "Remember," I continued, "You're just my bodyguard incase we're spotted. It won't be good if you start hitting anything that gets close to us." Buffy nodded to me, but I could feel her need to become violent because of the situation; it was rolling off of her in waves.

Walking into the building, we did our best to put as much distance between us and anyone visible as possible. In such a busy place, it was difficult. I hit a few people on their sleeves, causing confused looks to appear. It seemed Buffy was doing much better. Since she was quicker and much more agile and flexible than I, her attempts of avoidance were much easier.

The further we got into the building, the less crowded it became. As we stopped near the secretary's small desk, Buffy and I looked at each other, making sure we were still on the same page. We agreed earlier that I would wait to cast the Imperius Curse on the secretary until she was minutes away from giving the mayor something to drink. Buffy still wasn't comfortable with me using the spell, so I agreed.

Buffy was still standing straight nearly an hour later where my legs were cramping and felt like they were about to fall off. Thankfully, the mayor's distinctively pleasant voice appeared on her phone. "Sally, would you get me some water? My meeting has left me surprisingly parched. Thank you." As I took out my wand, I wondered if the Mayor always talked like that, and if he knew the too pleasant and too nice manner came off as very creepy.

"Imperio." I whispered, jabbing my wand in a violent manner at the woman after she finished replying to the Mayor. I felt her mind succumb to me in only a moment, putting up no resistance to the spell. She looked at me blankly, through my illusion of invisiblity. I spoke to her in my mind. "You will take this." I said, handing her the small vial. "You will slip it into the Mayor's drink." I said next, watching as she made her way over to a small refrigerator and took out a small, sealed water bottle. "Wait." I said in surprise, taking the bottle and the vial from her. The water bottle was still sealed, opening it to put the potion in would only tip off the Mayor and possibly get the girl fired. I knew what spell needed to be cast, but it worried me slightly. I wasn't an expert at the switching spell and barely used it at all in since learning it, but I hoped I was able to do it. I long forgot the incantation to the spell. Using mostly intent when performing it in the past. This was slightly more difficult than anything I'd done before. Switching part of an item with another was easy, but switching out only a portion of the water in the bottle with all of the potion was slightly more difficult. Not only that, but since the potion and water looked the same, there was no way of knowing if I succeeded without testing one or the other.

"What are you doing?" Buffy whispered at me, trying to keep her presence unknown to the blank faced secretary. I held up my hand to keep her from talking while concentrating intently on both bottles. I pictured both of the bottled in my mind, as well as the liquid inside the potion and only a portion of the water, I also pictured them switching places before waving my wand at the bottles. The switch would be instant, but with both bottles still looking the same, I had no way of knowing if it worked. I looked up at Buffy.

"Do you trust me?" I said, raising the potion for her to take. She looked at me in confusion before realization must have come to her.

"Why can't you try?" She asked before realizing the obvious. She looked over the secretary. "What about her?" I frowned at her. My question of her trusting me answered clearly with her own questions.

"If my spell failed, she'll go into a coma like state. We'd have to take her with us or leave her here. If we take her, we'll have a lot of questions to answer. But if you go into a coma, I'll take you back and get you awake in just a night." I explained. She looked a the potion and back to the water bottle; probably thinking about just how much she trusted me. The mayor's voice came over the intercom.

"Sally," the Mayor said pleasantly. "How's my drink coming?" I quickly told Sally to answer him normally.

"Sorry Sir, it will be just a minute." Sally said, stepping away from the desk again, a blank look appearing once again. I looked back at Buffy to see that she had swallowed the potion as the Mayor's voice came on.

"Still awake?" I asked. She nodded. I turned back to Sally, "Obliviate" I said, casting a quick memory charm to forget my earlier commands and the scene of me switching out the water with the potion. I commanded Sally again,

"Take the bottle to the Mayor." I said calmly. She nodded, took the bottle from the desk and walked across the hall and into the Mayor's office. Although I commanded her once more after my obliviation, I knew my command would most likely just be remembered as herself telling her what she needed to do next. As she made her way towards the Mayor, I concentrated on my link to her, and willed her to act normally again; to act as if she wasn't even under the curse. I felt her emotions as the Mayor took the bottle from her, examined it, and took a long drink from it immediately. I also felt Sally's worry as the Mayor collapsed onto his desk.

"Success." I said smiling, releasing Sally from her Imperius.

"Sir? Are you alright? Sir!" I heard Sally's panicked voice come from the Mayor's office. I grabbed Buffy's shoulder, preparing to apparate when I heard more shuffling inside the office, before the distinct voice of the Mayor was heard.

"Yes, I'm fine. I must not have gotten enough sleep last night." The Mayor however did not seem to be convinced that he was merrily tired, for the next thing Buffy and I heard was worrisome. "Faith." the Mayor said with force, most likely addressing her by phone, "Get over here. I need you to check the building. I'm locking it down." Buffy and I looked around us as security seemed to come out of nowhere, making their way to the exits for an apparant lockdown. I frowned as I latched on to Buffy's arm again. I saw Buffy's look of confusion at my touch before I whisked us both away, into the school library and behind a shelf of books.

"Well that was a waste of time." I said upon arrival. I looked over and noticed that Buffy wasn't doing so well with the instant change of location. She appeared ready to topple over. I grabbed her shoulders to steady her.

"Thanks." She said after keeping her nausea down. I let her go and nodded.

"What was a waste of time?" A voice appeared to the side of us. We both jumped in guilt a tour secrecy before turning, noticing Giles with an open book in front of him. It was just my luck that I picked the only dark corner of the library with someone else there. Giles, seemingly realizing that we were together in a nearly unused part of the library became suspicious. "What did you do?" He demanded at me, pulling Buffy away from me in protection. I frowned at my fellow countryman's instant accusation.

"What?" I asked, surprised at the look of anger on the man's face.

"Calm down Giles." Buffy said at the same time, taking Giles arm off her. Giles turned away from me and looked at Buffy.

"What were you doing with him?" Giles asked. Out of everyone in their little group, Giles appeared the most hostile to me after I admitted that I had killed before. Xander, though suspicious at the start, became more relaxed around me when it appeared that I hadn't hurt Willow in anyway after a few days. Willow was the most friendly, and everyone else didn't seem to care about me one way or the other, though the other Watcher, Wesley, seemed to look at me more than usual when I was in the same room as him. I thought about asking what his sexual orientation was, but realized I didn't want to know the answer.

"We tried to put the Mayor in a comma." Buffy admitted to him. Giles anger faded into curiosity. "It failed." Buffy explained, watching the little hope from Giles fade away. Giles put down his book, and guided Buffy away from me and towards the large table in the center of the library.,

"Explain." He said. I sighed and stood there for a moment before disapparating and appearing in my room at Willow's. I had no loyalty to Giles or the rest of the gang, so I was hardly going to sit there and watch as Buffy explained herself to him and I definitely wasn't going to sit there and be questioned myself. I did however owe a little to Willow and figured I'd better explain how it turned out. Willow had helped me in the early morning to gather supplies for the potion and even helped me prepare some of the ingredients. She was, besides Giles the only one who knew where to get most of the items required. She was also the only one who hadn't judged me so far. When I mentioned using the Imperius curse, Willow didn't appear outraged, only curious to the limitations of the curse. Although her enthusiasm for some of the darker curses was a relief after having to explain myself to everyone else, I wondered if it was a good thing that Willow didn't question my intent to use it.

After checking the house for a few minutes, it appeared that she was out. Shrugging, I made my way to my room and collapsed into my bed. I had been up most of the night making the potion and was dead on my feet. The side Apparition with Buffy hadn't helped anything either. Normally, I'd be able to do it without a problem, but the longer I remained without sleep, the more fatigued my magic and in connected, I became.

I was asleep only a moment later.
