Danny has been following Korra. He has been with her every moment on the peak. He heard how Zaheer tricked her. He saw Korra fighting for her life. He saw Tonraq join the battle. Danny wanted to aid them, but he could not. Zaheer was moving way too fast; Danny could not get a clear shot. He tried focusing on taking out P'Li, but there were too many metalbenders around her. He did not want to hit any of them.
He saw Zaheer fling Tonraq off the cliff. His heart raced and he swooped down, catching the Chief and flying him to the other side of the peak. He rushed back to Korra, who was fighting Zaheer. He heard the explosion and felt something wet hit him. He realized that it was blood and that the Third-Eyed Freak was no more. He saw Zaheer back away and fall off the ledge. Danny thought that Zaheer committed suicide and took Korra down with him. He was wrong. Zaheer gained the ability to fly. Danny heard people screaming "He can fly! He can fly!" Danny thought 'So can I" and he took off after Zaheer.
Danny is still trailing Zaheer, but he is not making any rash decisions. Danny does not want to act now. He does not want to save Korra at this moment. That will provoke Zaheer into slaying the airbenders. He tries to think of a plan. He turns around and witnesses two bison flying to the same cave. He notices Kai leading the rest of the rescue party. Danny knows that they are going to save the airbenders, while he goes after Korra then.
He watches Zaheer land and carry Korra into a cave. He chains her up over the mouth of a volcano. She shouts. She curses him for everything, especially killing her father.
"Don't worry, Avatar," he answers her calmly; he is not perturbed. "This is going to be over soon. Your suffering will end in this world and the Avatar is going to be no more. The cycle is going to break. You'll be poisoned and it'll be unimaginably painful, but completely necessary."
While the Red Lotus members are bringing out the poison, Danny springs into action. Staying invisible, he also becomes intangible. He zips to Korra and grabs her, transferring his undetectable states to her. He hears commotion and confusion buzzing behind him. He flies through the rock and he lands on top of the cave with Korra in his arms. He reveals himself and they hug. She cries a little due to fear and mourning.
"Dude, everything's chill and I mean it this time," he consoles her. "The rest have gone on the rescue mission."
"That's great news!" She smiles and claps her hands. "Thanks for saving me. Now, take me back to Zaheer."
"Kor, are you crazy? I know Zaheer is!" He is horrified. "I'm not going to do it and you don't have to do it."
"Danny, this is my fight, but I'm not going in there alone. I've got backup." She looks at him and he understands the message.
"Fine, I'll be your invisible fighting force."
"Here's the plan, ghosty. You take out as many goons as you can, okay?"
"Okay."
"And I need a favor."
"Anything."
"Leave Zaheer to me," she commands.
"Okay, make him suffer," he chuckles.
They prepare to leave. He makes them both invisible and intangible again. He floats through the rock and looks down at the scene below. Mako and Bolin have joined the commotion below. They are battling Ming-Hua and Ghazan respectively. Bolin has apparently unlocked his ability to lavabend.
"Do you see that?!" Danny whispers to Korra, almost losing his concentration and almost falling from the ceiling due to shock.
"I'm not blind!" Korra whispers back.
Danny scrutinizes the scene. There is so much chaos - something Zaheer should be enjoying, but they know that he is not. The master's plan has been foiled. The Avatar has somehow been rescued.
Danny spots Zaheer and zooms to him with Korra in tow. He places her behind Zaheer. She taps Zaheer's shoulder and he turns around, receiving a huge blow across his mouth. The sound of the punch echoes in the cave. Danny smirks. He is acquainted with being on the receiving end of one of Korra's punches. They sting; she has a good arm.
He leaves her to fight Zaheer while he takes on the other members of the Red Lotus, quickly picking them off one by one. Occasionally, he flies to Zaheer just to zap him with his ghostly powers, distracting and hurting the airbender. It is not necessary for him to do this; Zaheer is being creamed by Korra, but Danny decides he should at least make this fight entertaining for himself.
Chaos is everywhere. Everyone is fighting. Rocks, water, fire, and air whizz around. People are ducking and retaliating. Tonraq joins the fight, but Korra does not notice her resurrected father. She is busy beating Zaheer to a pulp.
Danny redirects his attention to the rest of the goons that have yet to be zapped by him. Some have run outside. He finishes off the ones in the cave with Tonraq's help. Mako and Bolin have disappeared, probably still fighting Ming-Hua and Ghazan. Danny hears a distant scream. It sounded like a woman's. He hears a rumble in the distance. Something it seems is crumbling down. Minutes later, Mako and Bolin emerge, walking to Tonraq. They decide to unite with Korra in her struggle with Zaheer. They rush forward toward the duel.
Before they get there, they hear a huge crash. They see Korra and Zaheer writhing on the ground in pain. Korra's leg is covered in a grayish metallic liquid: the poison. Zaheer is not so lucky; his whole body is coated in it. Zaheer screams and the sounds reverberate on the walls.
Danny flies to Korra and picks her up. He hears shouts from below. He is still invisible; he wonders how weird it looks for a writhing Korra to just be swooped into the air and carried away. He does not care though. His mission is to get out of the cave and to a metalbender. Tonraq, Mako, and Bolin are tailing them.
He speeds out and finds Suyin, who has been reunited with her daughter. The airbenders have captured the fleeing members of the Red Lotus and are celebrating their victory. Danny becomes visible and places Korra in front of Suyin.
"Suyin, Korra needs your help," he pleads. "She has been poisoned and you can remove the poison because it's metallic."
The three men join them and Danny reverts back to his human self. Tonraq, Mako, and Bolin gasp - Bolin's gasp being the most dramatic because he is Bolin.
Danny's secret is revealed. 'Oh well, it was bound to come out anyway.' Suyin focuses her attention on Korra and removes the poison from her leg. Korra stops whimpering and tries to stand up, but her left leg gives way. Danny catches her.
"Thanks, Danny. Thanks for everything," she hugs him.
"I've got good news and bad news," Mako starts. "Zaheer's no more and neither are the lavabender and the waterbender. Bolin and I took care of that." He is proud of himself, while Bolin flexes his muscles. "Also, the temple is destroyed thanks to Ghazan."
Everyone rejoices. Everyone who they have been trying to save is alive. That is the most important thing and they are very grateful. A huge threat has been stopped. This news eases their nerves better than any calming tea could ever do.
"Okay, I'm confused," Bolin begins. "What is the good news and what is the bad news?"
Danny laughs. "What do you think?"
"Well, the destroyed is bad. Zaheer and his guys being stopped is good, but they died and death is...bad."
Mako rolls his eyes. They all exchange looks: 'Let Bolin figure this out himself.' Jinora gathers air bison and they can fly back to Republic City.
Danny decides to go ghost for a while and fly alongside them. It feels nice to not have to hide anything anymore. He feels the wind ruffle his hair. He smiles. The terror is over.
'It's time to get back into vacation mode. After all, that's what the Ghost Zone sent me here for.'
