A/N :] Chapter Sevennnnn! Ah, the plot finally starts to make it's appearance. ^^ I hope this chapter is as great as my others have been. Enjoy!

After Wren had made the proclamation, and then proven it, it seemed generally accepted by the group. She was glad for this. The main questions on everybody's minds were 'why' and 'how'. And nobody could explain it. Nobody knew why Wren existed. Wren, on the other hand, didn't know why Aang existed. She thought she had been there first; now that she knew that the other Avatar was real, she WANTED to be the first, the only. But it turned out this kid was the first. He was frozen in an iceberg for the past century! She, on the other hand, was just...Wren. She couldn't explain her existence. It was dizzying to find out that your whole life, your whole existence, was probably a mistake.

There was a lot of discussing and arguing back and forth between Aang, Katara, and now she knew Toph, Sokka, Haru and Teo. Haru and Teo, however, mostly sat down and watched the brainstorm progress. Wren would intermittently put in her thoughts, but those times were few and far between. Aang eventually decided that, in all of his I'm-the-Avatar-therefore-the-leader-kinda glory, that he and Wren were to go into the Spirit World to ask Roku, the previous Avatar's, opinion on the matter. Wren stared at him blankly.

"And just do I do that?" she asked, mystified.

"It's a power of the Avatar's. We are the link between the two worlds, so it only makes sense that we can visit both. Don't worry, Wren. It's actually kind of fun" Aang explained, hardly masking his incredulity that she hadn't heard of this. It was now that she cursed Shiro. Along with simplicity, he believed that everything should be taught in it's own good time. He had never mentioned that Spirit-World visitation abilities. Aang offered his hand to her, which she took hesitantly. She glanced at the group, who were eyeing her with a sort of curious reverence, keeping their distance, except for Katara, who was concentrating on not looking at her at all. She didn't blame any of them. She was the anomaly here.

She and Aang went to the corner of the room, and he sat down and closed his eyes. Everybody suddenly went silent, watching him intently, Toph excepted, of course. Wren closed her eyes. She concentrated on getting to the Spirit World. Nothing was happening. For about five minutes, nothing. She opened her eyes a smidgen, and looked sideways at Aang. Suddenly, his tattoo started to glow faintly. It grew stronger and stronger, until Wren felt a jerk around her navel. She felt like she was being sucked through a tube. She was being squeezed, suffocated, smushed!!! She tried to breathe, and there was no air! No air! She gasped, and suddenly fell to her knees, still trying to gasp for breath. And then, she could breathe again. Aang was looking at her with a sort of apologetic look.

"Forgot to warn you about that, sorry" he said, smiling and scratching his head. Wren rolled her eyes, and raised herself up to full height, a full foot over Aang. Aang walked to a sort of pond nearby. He looked in it, and asked it politely.

"Roku, could you come here? I need some advice"

And then a head started to emerge from the shallow pool. His shoulders, his chest, his hands, and finally the tip of his robes came fully from the water, completely dry.

"Young...Avatar...." Roku started, but then saw Wren. His mouth hung open. Wren raised her eyebrow. Weren't the Spirits supposed to be wise and graceful? Right now Roku looked oddly child-like in his surprise. She could only guess why; only the Avatar could walk freely in the Spirit World. That much was known, even to the living.

"So, from the look on your face, I take it you see what's happening here. There are two Avatars. This isn't...right" Wren said just loud enough for Roku to hear.

"I-I never thought this would happen. It never happened before" Roku stammered.

"What never happened before?" Aang asked. Wren walked forward and elbowed him to make room.

"Two Avatars, dummy, what else? Roku, what do you know about the double-Avatar conundrum?" Wren asked. Short and to-the-point. Just the way Wren liked it.

"It is an ancient law. There's no man alive who remembers it. I would have spoken to you about it, Aang, when we saw each other before, but there was no evidence of their - her - existence. I thought it wasn't necessary"

Wren and Aang just looked at Roku with the same expectant look on their faces.

"The law states...that when the Avatar of the generation is...incapacitated for too long, and the world desperately needs his or her guidance, then the Spirits will...replace them. B-but Aang, you came back! And there was never a whisper of another Avatar. Yes, even the dead have ways of knowing about the Avatar" Roku added to Wren as she looked skeptically at him.

"You said that this had never happened before, so you couldn't have known that I existed anyway. You wouldn't have known how to look for me" Wren concluded.

"But there can only be ONE Avatar. More than one and the balance is upset" Aang said petulantly.

"That's all the law states. There is no law for this situation. All I can do is guess, and my guess is that the stronger of you will win out"

Wren and Aang looked at each other with worry and reluctance displayed clearly on their faces. Aang was just a kid, and she didn't know him at all, really, but she didn't want to fight him, or kill him. Far from it! What did that mean?

"So...we have to fight?" Aang asked. She could tell his thoughts were in line with hers. This comforted her. Roku just shook his head in obvious confusion.

"I cannot help you with this, Aang. I have no experience with a double-Avatar" he said as he shrank back into the pool. The two Avatars stood before the pool for a few moments, and then Aang grabbed her hand, and she felt the uncomfortable tug in her stomach, and then after a few oxygen-free seconds later, they were laying, gasping, on the floor of the Western Air Temple.

Wren sat, her burned arms around her burned legs, while Aang told the others what was going on. His voice sounded so remorseful when he got to the part where the Spirits had to replace him. But Wren couldn't bring herself to ease his pain and tell that part instead. When Aang finished, it was highly apparent that everybody else was thinking the same thing that she was; who was stronger? Was it her? If Wren had to admit it, she knew that she looked stronger than Aang.

She was riddled with scars from rock and fire and Spirits-know-what. She was older, more practiced in three of the elements than Aang could possibly be, he having studied them for a little over a year and she most of her life. But she didn't feel stronger. She felt weak. She shook her head, and her mind of that feeling. She was by no means weak. She stood up. The group watched her out of the corner of their eyes.

"Ahhg" she moaned, sinking back to the floor. Her burns, plus the short duel she'd had this morning, had really worn her out.

"How did I get like this?" she asked. The majority of the group shrugged in unison.

"We woke up yesterday and saw you just laying outside of the trap-door. It looked like you just collapsed there..." Sokka piped up.

"Trap-door?"

"The entrance and exit out of this place to ground-level" Toph explained. Wren nodded slightly.

"Katara...could you spend some more time on those wounds? They look painful - a lot like what I had when Azula hit me with that lightening" Aang murmured to her. She turned to him, eyes wide, trying to imply something - or accuse him of something, Wren wasn't sure - before she visibly crumpled under his questioning glance. She turned to Wren, and took some water out of her water-bag. She immediately began working on her legs.

To think that healing with water would be soothing would be natural. But, whoever had thought this had clearly never been healed by a clearly angry Katara. She was rough, not bothering to touch only the healed or un-burnt skin, or bothering to keep what was under her tunic properly under her tunic. Multiple times had Katara raised an arm, or Oh Dear God a leg, too high for comfort, only for Wren to jerk it back down and shoot her an angry glance. After thirty long minutes, most of Wren's burns were healed. She was able to get up and walk away, giving Katara only a cursory 'thank you'. She would have been more grateful but for the fact that Katara had been rough on purpose.

"Do you guys have any food around here?" she asked, rubbing her stomach. She was deathly hungry. She was shown the way to where the food was kept by the big, makes-Moose-look-like-an-ant-beetle sky bison, Appa. After a huge brunch, they showed her the rest of the way around the Temple. There wasn't much, just bedrooms and a food-hall that they didn't use. But then, they showed her the trap-door. As soon as she laid eyes on it, she started to formulate her plan. But after looking at it for a few seconds, Toph and Sokka pulled her along to go look at some wall-inscription or another.

She didn't pay attention to the lovely scenery, wall-paintings, crumbled upside-down buildings, or really anything else after she had seen the trap-door. She knew that something must have happened with Zuko. Why wasn't he here? What had happened to her? Why was she burnt? An awful thought crept into her head; what if Azula and Mai had attacked, and she was somehow knocked out?
But she couldn't figure out what their goal would be, sending her here to the Avatar, instead of a prison. They said she had been found just outside the trap-door...what if Zuko had placed her there and left? She could see why he would - Katara's healing abilities (though grueling), had helped her a lot. More than Zuko could, anyway. There was only one solution Wren could think of to both keep up appearances and soothe this wracking, hellish worry inside of her. Go through the trap-door later on in the night, and search as long as possible for Zuko. If he had stuck her here, he must have stuck around...he would have to - he's on the Avatar's side, now.

The day flew by fast, after she had solved her problem. She was already starting to like Toph and Sokka, and maybe even Aang a little bit. Katara never loosened up on the icy demeanor towards her, which she shouldn't have been surprised at. She wondered what Katara's problem was. Everybody seemed to maybe-like Wren, even the ever-quiet Haru and Teo. She hadn't done anything in particular to Katara either, other than water-whip her with her own water. Wren supposed that this was a bit of a low blow, but something to be this way about? Surely not. There must be something else to it.

That night, after waiting for hours for everybody to be good and fast asleep, she crept up to the trap-door. She climbed the make-shift ladder Sokka had made, and poked her head above the actual ground. She was amazed. It was completely barren. She hoisted herself up, and managed to sit on the lip of the door. There were a few boulders here and there, but other than that and a few grasses, the place was desolate. Bare. She could see what Zuko had been talking about. She turned around, and saw a shadow shoot towards her from behind a large-ish boulder. She raised her hands to defend herself, but it was too late.

A/N Sorry if there are a lot of typos in here, guys. I just got off work and started writing this, and now it's midnight, and I'm bushed. Let me know what you think :]
