Korra notices the dummie is frozen where the Icicle hits, but the icicle breaks and the dummie unscathed "*Sigh* This isn't the way to use Ice... Bubbles and Ice are both important, they have their values, i excel in making bubbles more than Ice, but they both have their values and i moderate between them, the tribe needs the most experienced, not the ones who just know how to make a large scale destruction, Ice is very cold, the more experienced, the colder you can make the Ice, eventually, you can make Ice to freeze anything in a 30 meter diameter, and by only using a single icicle! It has been done before, so it isn't impossible, huh? And there are islands in the sky, guess how they float? Bubbles! 5-7 people who are powerful in bubbles can make very large and dense ones, even as dense as steel! Some make very soft bubbles and cover them with gunpowder, thus making a landmine bubble! See? We have to moderate, because eventually we would become stronger only using water, stronger than an avatar! Well, avatars are strong... But we can still be our own avatars! Moderate, and we can be as powerful as Teacher, just do what i do."
