Alright. This is my first attempt at a Multi-Chapter story. Do not expect it to be incredibly long. I'm only expecting this to reach about 4 chapters, and nothing more.
I will get this done, no matter what. This story is coming to me so quickly an so full that theres nothing you, as a reviewer, can do to change the outcome of the story. I will update it at my own pace, but hopefully it will be done by the end of the week. Expect it rather quickly.
As always: in Katara's Point of View
Think of this as a prologue!

I promise you, there are no spoilers for episodes 7-9 in this. I personally made sure of that.
Any episode after those, as in 10 and beyond, I have no clue about just like the rest of you.
And I own nothing!

Surprise

It had all come so quickly, and at such a horrible time, I don't think there was anything I could do.

As we were getting ready for the first step of the invasion on the Day of Black Sun, Sokka quickly went over everything we needed to do. We were listening intently, nodding every time he went over something important.

…All of us besides Aang, anyway.

He was sitting there, listening of course, but he looked incredibly nervous. I suspected it was all of his nerves building up for the battle he was about to face, but just the way he handled made it seem like I was wrong. Every once in a while, I would catch the faintest hint of a blush on his face, him mouthing words to himself, and then he would continue fidgeting.

I decided to ignore this and continue listening to Sokka, who had just reminded us of the fact that the eclipse itself will only last the duration of eight minutes.

We started to make our way in to the Fire Nation capital when I felt a light tug on my wrist. I stopped automatically and turned to see Aang standing there, looking positively nervous.

"Katara, I need to tell you something…"

Out of the corner of my eye, I saw both Sokka and Toph were stopped mid-stride. Sokka in particular looked incredibly bothered. "Aang, what are you doing?! We need to go!" he yelled out in annoyance.

Aang acted as if he didn't hear this and just looked right at me. "Katara… I love you…"

I didn't even know how to react to this at the moment. But instead of looking at Aang, I turned to look at my brother and Toph, looking for some indication of what they thought. I saw a slight smirk appear on Toph's face, but watched it fade away only seconds later. Sokka, on the other hand, was glaring at Aang. I don't know if it was because of Aang's horrible timing, or the fact that the Avatar just confessed his love to his little sister.

I turned to look at him again, but still no words came to me. I couldn't even smile. I was, to a degree, thankful that Aang continued. He still sounded completely nervous, a signature blush still bright on his face.

"I've wanted to say that for a really long time. A lot of things have kept me from finding the right words… but… I love you. There's no other way to put it."

I had absolutely no time at all to even begin saying anything before I felt Sokka take my arm and pull me towards him, shooting another glare at Aang.

"What is there about an 'eight minute eclipse' that you guys don't understand?! Let's go!"

And we did. We didn't say a single word to one another as we picked up our pace, entering the capital at a forced run.

Aang was as far away from me as he could be, a blush still lingering on his cheeks, but his face bearing a look of determination that I hadn't seen before.

I let all the words he said to me earlier slip from my mind as I let the impending battle be the only thing that occupied my thoughts, wanting nothing more than for this invasion idea to work out.

Too bad it didn't happen that way.

We lost.

We made our way toward the Western Air Temple, which was the closest non-Fire Nation territory we could find.

As we were flying through the sky, tired and battle torn, I felt Aang's gaze upon me. I turned to look at him, and I frowned a bit the moment our eyes met. Reactively, we moved away from each other so we were now sitting on entirely opposite sides of the Bison's saddle, turning away from each other, and looking out at the redish-yellow clouds that were floating in the sky.
