It was time for Aang's Waterbending lesson, and Katara couldn't find her student anywhere. She'd seen him heading in this direction earlier, but beyond that she had no idea. There were any number of side passages he could have turned down, and hundreds of rooms for him to have gone in. If she had to search every single one of them, she would.

"Aang? Aang, where are you?" she called. No answer. She sighed and shoved open yet another door, freezing when she saw what was inside. She'd found Aang. He was tangled up with Zuko, kissing him passionately. Her Aang's hands roamed freely across Zuko's body. He should be exploring her that way. His lips should be caressing hers not Zuko's. Both boys were half naked, and by the looks of things, they were well on their way to being completely naked. Spirits only knew what would happen then. She had to stop them. Now.

"Aang! What the hell do you think you are doing?" They jerked apart instantly, looking at her with identical expressions of guilt. Well, Aang should feel guilty for cheating on her. And Zuko should feel guilty for taking advantage of Aang like that. "Is this what you two do when you're supposedly having Firebending lessons? You head to some isolated part of the temple so you can molest Aang?"

"I was not molesting him!"

"I asked him to teach me how to kiss, Katara. We just got…a little carried away, is all." Zuko looked at him, his expression unreadable. Katara was shocked. Why would Aang feel the need to get kissing lessons? He was a wonderful kisser. She blushed slightly, remembering the feel of his lips against hers before the invasion. "Although, in addition to learning a lot about kissing, I realized that I enjoy kissing Zuko more than I enjoyed kissing you." Hope was beginning to dawn on Zuko's face. "I'm sorry, Katara. I never meant to lead you on. Of course, you've never been interested in me, so it's kind of a moot point, isn't it?" He reached for Zuko's hand, lacing their fingers together.

"I-I am interested in you, Aang! I just didn't want to distract you from defeating Ozai!" A skeptical expression crossed Zuko's face. "It's true!"

"Katara, you act like my mother! Even after there was no way you could deny knowing I have-had feelings for you." Katara flinched slightly as he changed tense. "If you were actually interested in me, and you were serious about me, you would have shown some sign of it. I've seen you try to act, Katara. You're not that good at it."(A/N: He's referring to Ep. 106 "Imprisoned") Her eyes filled with tears. It wasn't possible. She couldn't be losing Aang. Not to Zuko. Aang had liked her since the moment they met! Zuko had tried to capture him from the moment he had set eyes on him. It wasn't fair. Aang was starting to look even guiltier. Zuko rested his hand on Aang's shoulder, said something to him too softly for Katara to hear. Aang nodded, and then stood up. He walked over to her and hugged her gently. She clung to him, not wanting to ever let go.

"I'm sorry. I really am. You're like family to me. I would never want to hurt you. But this thing with Zuko…I can't explain it. It's not just physical. I feel-" He paused. "I've never felt so deeply about anyone before." He smiled briefly over his shoulder at Zuko. "Aunt Wu said if I followed my heart, I would be with the one I love. At the time, I thought she meant you. Now I think she was referring to Zuko, even though I didn't even consider that at the time."

"Aunt Wu told me I would marry a powerful bender." Aang smiled briefly.

"I'm hardly the only powerful bender in the world, Katara. Take Haru, for example. With some more training, I'm sure he'll be quite powerful, too. And, he definitely has a crush on you," he hinted. Oh, Spirits. Aang was trying to match make for her. He wouldn't be doing that if he still had feelings for her.

"Oh, all right. I give up." She glared at Zuko. "But if you think I'll ever forgive you for stealing my boyfriend, you have another thing coming." She turned on her heel and stormed out, slamming the door behind her.
