It was quiet a scare Zero put everyone through, they all thought he was gonna die, Katara helped made sure Zero was alright by using her water healing, but some reason Zero felt weak. Katara had walked out of the room were everyone was waiting, "how is he holding up mom?" Bumi asked concerned, Katara was a bit unease, "he's fine for now, but now he needs some rest," she instructed all of them. However Zero against Katara's advise called out to his child, "Charlie?" and soon the youngest walked to his father's room.
The only light source was the sun shining through the window and Charlie looked around his father's room seeing neatly stacked books organized in alphabetical order, and then saw Zero laying on the corner of his room. Zero motioned his son to come closer, Charlie set down next to his ill father, Zero held out his hand for Charlie to hold, "Charlie you have to fight. You can't keep running for the rest of your life... It's noway to live," Zero told him.
Charlie shook not sure how to respond, "I can't, I'm too scared dad," Charlie said, but Zero shook his head, "no Charlie. It's all in your head. They sent the monster to kill you. Because they're afraid of you," Charlie couldn't understand, "Charlie. You're not like the others. Not even your brothers. You're much more stonger than you realize. So strong... You could surpass me." Charlie contemplated the possibilty of how can that could even be true, "how? I am all alone," Zero shook his again, "no Charlie. You can't think like that. You're never alone. But even if you were. That doesn't make you weak. Only if you believe that you are will it be true," Zero told him.
Zero coughed once again, but proceeds, "Charlie. All I ever want. Is for you and your brothers is to be happy. To be free... But you can't let fear control you," Zero warned his son, "... Alright. Thank you dad," Charlie told his father, then left be to rest.
The next day Ju came to visit Zero at his home, she heard that he wasn't feeling good, and wanted see him, "are you sure you're alright?" Ju asked worryingly. Zero looked at her with a smile, he loved seeing her, "I'm fine. Trust me," Zero answered and Ju just pouted, before she can say anything else Pema came with Zero's breckfest which was bowl of warm noodles, "careful Zero it's still hot," Pema told him then turned her attention towards Ju.
"It's nice knowing he has friend like to have by his side," Ju blushed feeling a bit soft, Pema left two alone, but as she left Ju spotted Charlie standing right out the door, "Charlie. Say hello," Zero told him. Charlie timidly came into full view still wearing the ruined straight jacket, Ju looked at him in surprise seeing that Charlie had the same face as Zero, but she couldn't help to stare at his new scar which in turn made Charlie insecure, trying to cover it with his long sleeves.
Ju saw that she made Charlie a bit upset, "I'm sorry," she apologised, but didn't seem to help much so he just ran off, Ju felt a little horrible. Why did she had to stare, "don't be. Upset," Zero reassured her, "Charlie never met. Other people before," he told her while slurping up his noodles, "why is he so upset?" Ju brought up. "He had it rough. Like me. But he is still trapped. And I can't be there to help," Zero told her, "but why? he's your son," Zero turned to her, and Ju saw that Zero gave a sadden look and realized why, "oh... I see," she said heartbroken.
Zero finished the last of his soup, set the bowl aside, and gentally grabbed hold of Ju's hand, "Ju. I think you're pretty. When I first saw you," Zero confessed making Ju blush. "And thought you were really cute," Ju confessed as well, they both leaned in closer and gave each other kiss and after that Ju went on home.
It was getting dark and Zero was playing with Rohan on his bed while Korra made sure Zero's bed is comfortable, "alright sleep well Zero you need to get well," said Korra, then picked up Rohan to put him to bed. When Korra left Charlie came in to see his father one more time before he turned in, "Charlie. You can't just run off. Just because someone's staring," Zero told him, but he can tell that he wasn't here for that, "dad? who was that girl?" Charlie asked. Zero took a few moments and then spoke, "her name's Ju. I met her older brother in an alley way. When I first came here," Zero told him.
Zero had told Charlie everything he had gone since he arrived to Repiblic City and Charlie loved hearing his story, but it was time for bed, but Zero wanted to say one last thing, "Charlie. Always remember. That I love you and your brothers," Zero said and Charlie took it to heart and left his father to rest for the night.
The next morning Korra and Katara had slid open the door to Zero's room to check up on him, "rise and shine Zero, it's a brand new day," Korra called out, but Zero didn't respond. Korra figured that Zero must be in very deep sleep, "c'mon Zero you can't sleep through the whole day," Korra tried again and again Zero did not respond.
Katara noticed that Zero hasn't moved at the slightest so knelt down next to him, and Korra started to get worried "Korra go get Tenzin," Katara told the Avatar and without question Korra ran to get her air bending master, but it will be too late.
Zero has passed away.
