Another chapter? Hell yeah it is. The story gets developed a little more here, more info of relationships are shown and blah, blah, blah, ignore me and read on!

Zuko walked down the long hallway towards his room with a couple blood bags in hand. He wanted to curse at the sun that was showing through the large windows for its harm it could cause his girlfriend. "Zuzu," He ignored the call from his sister as he continued down the hallway, "Aw, don't ignore me." Zuko stopped and sighed, he knew that she would follow and bother him until he finally talked to her. He turned to his sister and narrowed his eye. Azula's usually flawless white skin was now red scales, the usual identification of a Demon. Unlike her brother, Azula was given the Mark of the Demon when she accepted it, unlike him who it was forced upon, and it was rare, if even possible, for him to turn into his Demon form. His sister loved to tease him about it. "Where are you going with that blood?" Her evil grin agitated him even more. "You wouldn't happen to be having some guests over would you?"

He took a calming breath before deciding to answer her, "You know Ty Lee is here Azula. You know better than anyone that this is hard for me to deal with this. Can you just for this once let me off the hook and you can berate me twice as much after this okay?"

Azula frowned, "Gosh Zuko, you're such a downer. Can't a sister just inquire what her big brother is up to?"

"With you, there has to be some ulterior motive," Zuko said truthfully.

"You know, it was a lot better when you just let me make fun of you," Azula turned her skin back to its usual porcelain tone. "Now I know why Father likes me better."

"It's because whenever he looks at me, he sees our Mother," A new feeling managed to make its way into Azula's heart: sorrow. "No matter how much you may look like her, he still hates himself whenever he looks at me. Though that's all I can see when I look at you, even if you are a horrible person."

She held back tears she thought she would never get, "You're a bastard Zuko…" Azula turned and walked back into her room, slamming the door. He continued walking down the hall to his room, knowing he was going to get a horrible backlash from either his Father or Azula but he pushed it to the back of his mind. Just like he had told the servants, on his side of the house, the drapes were pulled shut. The only thing that illuminated the halls was either lights or the small amount of sun from the windows he had passed. When he finally got to his room, he let his head fall and took a deep breath, knowing on the other side of his door was what he considered his biggest mistake. Zuko finally opened the door and saw her on his bed, it looked as if she was dying. Her chest rose and fell rapidly, he could see the sweat forming on her skin. Unfortunately he knew this was what happened to all Vampires. The last of her human blood as being used up in her body, fully changing her into a creature of the night, there was nothing he could do except watch as she suffered. He softly shut the door behind him and walked over to the bed, getting on his knees beside the side. Zuko looked at her flushed face and her half lidded eyes, he moved stray strands from her forehead and kissed it.

"I'm sorry this had to happen to you," He whispered against her forehead. "I never wanted this to happen to you…" Tears formed in his eyes, "I wish I could have chosen a different life…I wish I lived with my Uncle, he would have kept me off this path and you wouldn't be like this."

Ty Lee weakly smiled and cupped his cheek in her hand, "If you lived with your Uncle, I would have never met you through Azula." She winced as a sharp wave of pain flowed through her. "Can I have some of that blood?" He nodded and put the bags on the bed and he unscrewed the cap. "Will it taste any good?"

"I don't know Ty," He said. Zuko put the end to her lips and tilted it so that the blood slowly poured into her mouth. She took slow gulps, relief began to wash over him as it seemed to help her. When the bag was empty, she tried to suck out the little traces of the red liquid out. He quickly unscrewed the second one and replaced the bag, she quickly sucked down that one also. Again, she finished the bag and tried to get every last drop.

Though she still looked bad, he could see her get a little bit better, "Is there anymore?"

He shook his head, "Not for a while, most of our supply went to-" He stopped himself before saying 'bloodsucker', he would be insulting his own girlfriend by using that name. "To the Vampires," Zuko finally said with much anger. "I have some men delivering more very soon, I promise." He didn't even know the truth behind his own words. It was true that he had some men out getting her blood, but with current delivery to the Vampires, he wasn't sure if any more blood packets could disappear so easily.

Ty Lee groaned, "I'm so thirsty…"

Zuko knew he had to get her blood or things might turn dicey for their relationship, nothing says an end of a relationship than having to defend yourself from a recently turned Vampire. It wasn't like he could get one of the servants in here and have her drain them. All she needed was some more blood whether it is cold or warm. He ran his hands over his face as the idea of letting her drink from him came to mind. There were ways for him to allow her to gain sustenance from him without her drinking him like a Capri-sun or turning him, but he had to be careful for her venom not to get into his veins and he had to trust her self-control. Getting up from the side of the bed, he walked over to his closet, he grabbed one of his ties. Walking back over to Ty Lee, he pulled up his sleeve and tightly tied the tie around his arm, Zuko could already feel his arm starting to get numb. He sat down on the side of the bed and reached into his nightstand, grabbing the knife that his Uncle had given to him when he was younger. Zuko stared at the symbols for the knife for a while before looking back at his girlfriend, "Ty…I need you to promise me something. I'm going to give you some of my blood, but you need to control yourself. You can't bite me or let any of your venom get into me, only use it to close up the cut. Do you understand?"

"But Zuko-"

"No buts," He said, "Do you understand?" She meekly nodded before he cut himself, Ty Lee jumped a little at the sound of pain he made, then the smell invaded her nose. It was so welcoming and inviting. The blood that was now leaking from Zuko was calling her to it, she crawled over to him, controlling her new instincts. Her doe eyes looked up at him, she saw fear in his eyes but he gave her an encouraging smile. Ty Lee swallowed the venom that was dripping in her mouth as she attached herself to Zuko's arm. So many emotions hit Ty Lee as her tongue tasted the blood of Zuko, happiness, love, excitement and even lust. She couldn't even think as she drank from him, her self-control was hanging on by a thread. If pure happy emotions could have a taste, it was this. The feeling of thirst and hunger disappeared fast as she took long drinks from him. Ty Lee noticed him start to fade, she gathered venom on her tongue and ran it over his cut, it quickly disappeared. She made sure to clean his arm up of any trace of blood until her eyes made contact with the knife he had used, it was still dripping fresh blood. Moving his arm closer to her, she licked off the remainder of the blood before licking her lips. She was proud of herself for not controlling herself even though she wanted to drink it all. Ty Lee wiped her mouth and looked up at Zuko. His face was paler than usual as he untied the tie, both of them now knowing it had been pointless.

"Zuko," She breathed, Ty Lee moved him so that he was lying back on the bed, his head softly resting on the pillow. "I took too much didn't I?"

"Just a little," He said, "But you're looking a lot better." Ty Lee looked a lot better now that she had drank some warm blood, she looked better than usual. "As long as you're better, I'm happy."

She held his hand in hers, "I don't want to be better if that means that I'm hurting you…"

"It will teach me to not get mixed up in this bullshit," Zuko weakly laughed, he mostly laughed because of his joke, but he realized the roles were now reversed between them. "I just need to get some fluids and food in me…maybe a little sleep, but I'll be fine. Soon enough…I'll be able to take you to that spot in the park you like so damn much." Zuko kissed her hand, "I would love to see that smile on your face again."

Ty Lee cuddled up next to him, resting her head on his right shoulder, "I hope you can Zuko…"

"So, you're the one who is watching over my little sister?" Sokka asked as he looked over the secret Cloud Child.

"It would seem so," Aang returned the weird look as Sokka looked closer at him. "I don't mean to be rude here, but can you not look me over? It's making me a little uncomfortable."

Sokka rubbed his chin, "You look a lot like the Avatar."

"He's not the Avatar, trust me, he can barely even lift me up," Toph commented. Sokka looked towards her.

"And your voice sounds familiar," Sokka continued, "Like the person who sunk me down in the ground and threatened me."

"Sokka," Katara finally spoke up, "This isn't a conversation we should be having around all these people." She pointed out, he looked around to see the other students passing through the halls. "And I can personally tell you that he," Katara nodded towards Aang, "is not the Avatar. I've seen then both in the same room at the same time. I would be more worried about the people around you then Aang." Katara shot a look at Suki and Yue who were behind Sokka. "And he told me to tell you that he's sorry for your nose, but you deserve it for being a complete idiot that needs to open up his narrow minded ways and realize the real world that is around him…or something along those lines."

Toph smirked, "Actually, that was exactly what he said."

"Well you can tell him the next time I see him, I will be ready to fight and not have to sucker punch him to gain the upper hand," Sokka told her.

"If I were you I would watch what I said," Aang informed Sokka, "The word is that the Avatar goes to this school and he is 'watching us all'." Sokka bit his tongue immediately.

"Oh, and he said to tell you Yue that he was flattered by you coming onto him, but just don't try to track him again," Katara remembered. Toph's hand became increasingly tight around Aang's, to the point of probably breaking a couple bones, but he kept quiet.

Aang cleared his throat, making sure there wasn't any trace of pain in his voice, "We should probably get going, he wants us to get you back to my house as fast as possible."

"So I can't see my sister any longer?" Sokka asked.

"I'm only following directions. I was also informed specifically to not let you to my house…he wasn't specific about them though," Toph squeezed his hand again, "Wait, never mind he was. You can see her tomorrow or talk to her later tonight. We'll let you say good bye alone, Katara met us outside." They both left as Toph angrily whispered something to her boyfriend.

"I don't trust him," Sokka told his sister.

Katara rolled her eyes, "And he was told not to trust you because you tried to trick the Avatar, see? No one is trusting anyone. Once the Avatar is done cleaning up the mess you have created, I'll be back home. Just go home and try not to try and get me killed anymore okay?"

Sokka growled lowly and left with Suki quickly behind him. Yue gave Katara a small smile, "Are you still mad at me?"

She rubbed her eyes, "I don't know Yue, I've been so busy with everything, I haven't had time to really be mad at you. Everything is just flying at me and it's hard to keep up."

Yue hugged her friend, "I'm sure everything is going to be fine, even if your brother doesn't believe it, I think you're going to be safe under the watch of the Avatar." Her face lit up, "I almost forgot." She dropped her backpack and dug through it before pulling out a weathered book which Katara recognized as her spell book. "You didn't take this with you when you left and I thought you might want to have it. I hope you don't mind that I've been using a couple spells from the book also."

Katara put the book into her backpack before giving Yue a once over, "You used the spell to make your skin look more radiant didn't you?"

"Maybe," Yue smiled, "And I used a couple to get rid of the dark circles around my eyes."

"Get your own book Yue," Katara laughed, "I'll see you tomorrow." They hugged once again before Katara left the school, not noticing Yue's eyes lingering on her a little longer than they should have.

Toph sighed heavily as she switched from supporting her chin with her left hand to her right. Katara watched her opponent with a bored gaze before looking down to the chess board between them. She had suggested the game with the Earth Born to hopefully further their friendship, but she had no idea how much Toph could get worked up. Toph looked from the board up to Katara, being met with a neutral look before looking back to the board. Her fingers fluttered over a piece before moving quickly to another. Katara felt her boredom drift away when Toph finally picked up her pawn and moved it forward, but not putting it down yet. Toph's eyes again checked Katara for any sign until she finally placed it down and let go. In one sweep, Katara grabbed her bishop and replaced Toph's pawn with it, placing it on the side of the board, "Checkmate." Toph groaned loudly as she collapsed on the floor.

Aang held his folded hands in front of his mouth as he observed the game, "Let me try."

"I wouldn't suggest it Twinkles," Toph said as she sat back up, "This is the third game I've lost to her and I use to play with my maid all the time. You haven't even played this game."

He moved her aside easily, "I think I have this." Katara smiled, hoping she could ease tensions between her and Aang. Though she knew that he would show no interest in her the way she had interest in him, it wouldn't hurt to strengthen the relationship between them. As long as she could get him to talk to her like an actual friend, she would be happy. She set up the board again as Aang stroked his chin as he looked over the board. He looked up to her and she smiled again. "Who goes first?"

"You," She told him, "Would you like me to explain to you where each piece moves."

Aang looked back down at the board and shook his head, "No, I think I got this, thanks though." Her heart leapt, she was making progress! He moved his pawn forward, she also moved hers. Quickly he moved another which she matched again. His pace of moving pieces was a lot faster than Toph's which surprised her at first, but she continued with him. Katara looked up from the board to see Aang staring at her. A slight blush came across her face, "You know, you're very light on your feet when it comes to lying, like how you lied to your brother today." He moved his bishop.

Katara moved a pawn, "Thanks, in my down time, I think about excuses I can use. I knew my brother would have questioned you about this whole thing." Aang moved another piece without looking at the bored, Katara kept eye contact with him.

"Just like you are with lying, you are quick on your feet while playing this game, would you agree?" Aang asked.

She nodded, "I would have to agree," Katara moved her piece to take one of his pawns, "It's helped me win a lot when I'm quick with my thinking and plans." She was surprised to see him take one of her pieces.

"Though while I believe that you are very good…I think you might need some more work, because let's say you're distracted," Aang took out one of her pawns, leaving her King trapped, "You're left wide open. I believe that's checkmate."

Katara looked down at the board with amazement, he had beat her on his first time playing the game. "Wow nice Twinkle Toes, how did you do that?"

"That, is something I cannot tell you," Aang smiled, "You'll have to learn yourself." He stood up from the table, "I would suggest staying here and learning if you want to get better while I go out and check on the city." Aang left to his room while Katara was still in shock, Toph took her place again.

"I can't believe he beat me," She finally spoke, "He didn't even try."

"Yeah, he has that annoying trait. It's the only thing that bothers the living crap out of me," She said as she looked at the board, trying to think of a plan.

Katara reset the board, "Don't you want to go out with him? I thought you two were partners or something like that."

"One of us needs to watch you," Toph told her, "If any Vamps decide to bust in here…or even find this place, it would be good to make sure someone is here to defend you."

"I can protect myself," Katara said, "The only reason why they got me was because they took me when I was sleeping…bunch of cowards."

Toph laughed, "Yeah, that sounds like Vampires…oh…sorry, I keep forgetting that you're a Half Blood." Katara took that as a good thing, hoping with more time Aang and Toph saw her as a person, rather than a Vampire. "How good of a Witch are you anyways?"

Katara extended her hand over the board and the pieces rose up in the air, floating and flowing into different shapes until she lowered her hand back towards the board, the pieces going back to their original places, but now a different color. Katara's pieces were crystal blue while Toph's were green marble. "I'm pretty good." Toph's face turned to discomfort as she looked down towards her chest.

She pulled her shirt away from her chest and looked down, "Where is my bra?!"

Aang came into the living room in his jacket, his mask hanging around his neck and Toph's bra on his head, "I assume this is your doing?" He pointed to Katara who only laughed in response. "I forgot how much Witches are like magicians," Aang tossed Toph her bra, he rolled his neck as he got prepared.

"Can I ask you something Aang?" Katara asked.

"What's up?"

"Why was that your choice for a costume? I understand the point of the mask is to keep your identity, but how many choices did you go through until you got there?"

Aang pulled the mask off of his neck, "This is actually the first costume choice I had. The arrows on the jacket," He turned his body so she could see the blue arrow that went up his back, "Represent the old Cloud People. They use to have these tattooed on their bodies. This mask pumps cold air for me to help make my powers strong, especially when it's humid. Come here," He told her. Katara got up and came over to him and he placed the mask on her face. Aang tightened the bands around the back of her head and pressed the button on the side, she felt the cold air starting to fill her lungs.

"Whoa," A deeper version of Katara's voice came out and her eyes widened, "My voice is deeper!"

He laughed and took it off, "Did you think I was just deepening my voice or something?"

"I didn't really think about it," She admitted with a chuckle.

Aang put his hood back up and the mask around his head, "I'm going to stop by Teo's and get a couple things before I go out. You know how to contact me if you need me." Toph came over and gave him a kiss.

"Stay safe Twinkle Toes, I've seen how you like to get around," She teased.

"I'll be fine," He tightened his mask over his mouth and pressed the button, "Ah, nothing beats cold air.

"Be careful Aang," Katara offered her own words as the couple looked over to her.

There was a moment of silence before Aang spoke up, "I will, just make sure you don't drop any bras on my head again." She smiled as Aang left, Toph coming back and sitting in front of the board again.

"So Katara-"

"No, you cannot distract me like Aang." Toph grumbled as Katara made the first move.

He flipped the knife around in his pocket as he saw him sitting on the side of the building, Zuko couldn't wait to get his hands on him. Zuko had finally tracked down the Avatar and was going to make him pay, for everything. All he needed to do now…was get the courage to walk over and use the knife as he planned to use it. A train loudly passed by all the stories below them, creating enough of a noise for him to flip out his butterfly knife and quickly walked as quietly as he could towards him. He got close enough and he prepared to stab him, only for the Avatar to turn around and bring a fist up to his chest. Zuko felt an electric shock go through his body and flew back into the outer ventilation system. He tried to move, but his body didn't respond. The Avatar got up and calmly walked over to Zuko, "I was wondering when you were finally going to attack, I was sitting there waiting for you."

Zuko continued to try to get up, "What did you do to me?"

He heard him chuckled as he held out his fist, "This is what my friend likes to call the Electric Knuckles." It was a plastic version of brass knuckles with exposed electrified metal on the end. "I personally think of them as my 'Thunder Fist'. You know, since I'm a Cloud Child," He laughed, he sat down on the vent next to Zuko. "Not only does it deal an almost lethal dose of electricity to the body, it temporarily paralyzes you…well, that's what he tells me anyways."

"When I get my hands on you…" Zuko seethed through his mask.

Aang held up his hands, feigning fright, "Oh no, I'm so scared." He pulled off Zuko's mask to see the angry glare from Zuko, "You know Zuko, I've never hated you. I've never really had a real reason to actually feel hate towards you. You used to be a good guy, before you got that." Aang briefly pointed to his eye patch. "Though you might not actually know the real me behind this mask, I knew you. After everything between us, the time I blew you into the way of that bus, the time you blasted me into the bay or the time that you kicked me into that trash compactor," He chuckled again, "That was a nice one, I've got to hand it to you. But with this Half Blood…this is where I'm starting to get very annoyed with you Zuko. Now, I know you are, as you told Katara, personally invested in this because of what happened to Ty Lee. I'm very sorry about that, it must be hard to deal with that."

"Don't patronize me," Zuko growled.

"I'm not," Aang told him, "I actually feel bad that it had to happen when I saved Katara's life. You're getting desperate and I can see that. You must care a lot about her don't you?" Zuko didn't answer, he wished he could punch him in the face. "I have someone I care about too and I would be in your shoes if that happened to her. Because I know the person that lives in here," Aang poked his chest, "I want to help you Zuko…but with the people you are mixed up with…and your Father…I don't think giving you the last part of the cure would be a good idea. You need to be the Zuko that can use his powers for good and save your girlfriend from becoming one of those sewer dwelling Vampires." Aang stood up and straightened his jacket. "You know Zuko, one day, I think you and I can be friends and we could do good things for this town. Just think about it, okay? Think of what's best for Ty Lee." He jumped off the side of the building as Zuko finally regained control over his body and rushed to the side to watch Aang almost fly through the city. He couldn't help but let Aang's words sink into his mind as he went towards the stairs.
