Katara and Toph had been searching for hours for the bald monk but still couldn't find him. The images kept swirling in their heads, but kept searching on desperate to find him.

Aang went on, getting farther along the trail. He started remembering the good times they all had during their adventures, it made a tear appear and he didn't care, as Aang walked slowly, he started crying for he would miss his friends too much but he kept on walking, sobbing with every step, he started regretting but reminded himself that it was for the best. Katara and Toph eventually checked the nearby mountains and saw the note Aang had left on the tree it read:

Guys,

If you've found this letter, I've already gone, I'm leaving you for my heart can't take it, I must get as far away from you as much as I can. Please take care of Momo and Appa for me. Don't follow me; I have to find the answer to my heart aches by myself.

Sorry,

Aang

The were left speechless as the sun set behind them, each of them started crying, even Toph who was the un-emotional one cried like someone important to her died. But these two determined girls wouldn't give up so easily, they went back to camp with the letter clutched in Katara's hands.

They arrived and showed the letter to Sokka and Zuko, "WHAT?!" , Sokka screamed, "He's leaving us!!!, just because his heart hurts!!", he continued, Zuko interrupted Sokka's tantrum saying, "You idiot, he doesn't mean it literally", the prince said, "It means he has a love problem, apparently it's a big one because had to ran away to relieve it" , he continued, "But who would cause Aang that much heart ache??", they didn't have a single clue of his whereabouts or the cause of his problems but they didn't care, all they wanted was Aang back so they packed up and started their search.

The sun had set and the moon started appearing, it was full and one of the most beautiful sights you could see but Aang didn't care, he didn't care about anything right now but his friends and a solution to his problem. He decided to take a break so he scaled the mountain looking for a spot that he could make a cave using his earth bending, once found the spot he waved his arms in a circular manner slowly creating a small cave. Aang gathered some wood and set it on fire. The night was cold and unforgiving, he curled himself into a ball in his cave and cried himself to sleep
