Aang lies on the couch in Suyin's office while he slowly wakes up. Aiwei's hand slides under his head and a green bottle is placed at his lips. Aiwei tilts the bottle so some of the liquid flows into Aang's mouth.

Aang's hand as it slowly twitches and he lifts a finger while the Beifong sisters look down on the Avatar. Suyin rests her right hand on her chest in relief, though Lin angrily turns to her half-sister, her fists clenched to her sides.

"How could you let this happen?!" Lin says, "You assured me this was one of the most secure places in the world."

"It is. I don't know how this happened. Obviously this was a well-planned operation, so," She frowns at Lin, "don't blame me."

"We searched the entire estate. There's no sign of them." Kuvira says

"Well, keep looking!" Lin demands.

Kuvira gives a bow and departs as Aang slowly sits up, "Is- is everyone okay?"

Lin's angry expression softened, "We're all fine. What about you?"

"I've been through worse." Aang replied.

Aiwei stands up, "It would seem they had some inside knowledge of Zaofu. They must've been working with someone."

"Maybe one of the guards?" Aang suggested, "It had to be one of them. No one else would know the city right?"

"I agree."

"Question them all!" Suyin ordered, "Whoever betrayed my city will suffer the consequences!"

----

Aiwei sits at one end of a small table in the interrogation room with a guard at the next. He went through guard after guard, asking them questions to catch the one who betrayed the city. Aiwei would look back at Lin and shake his head to signal that the guard was not the culprit.

Korra looks at Lin defeatedly after the latest guard. Lin nods to Aiwei to question the next suspect.

"What was I doing last night?" Varrick repeated, "Same thing I always do. From nine to ten, I checked my body for ticks. Lyme disease is a serious killer." Everyone else in the room looked at him with disbelief, "Then I did my nightly," Varrick stands up with a leg on a chair and exercising while demonstrating the workout, "Varrick calisthenics, followed by," He stops exercising, "thirty minutes of breath holding. I filmed the whole thing if you want to watch it."

Aiwei had a hand on his head while Korra has a hand on her mouth to hold in her laugh. Mako pinches his nose bridge from annoyance. Suyin has two hands clasped in front of her mouth.

"That won't be necessary." Aiwei replies.

Varrick and his assistant leave the interrogation room and close the door behind them.

"Maybe it wasn't a guard after all." Lin says, "Maybe it was someone a little higher up the food chain. Aiwei, why don't you question Su?"

"Lin, stop! Your sister was not involved!" Korra said.

"No," Suyin walks over to the chair, "I'll gladly be questioned. I have nothing to hide." She sits down.

Aiwei looks to the side, a little reluctantly, "What is your full name?"

"Suyin Beifong. I'm the daughter of Toph and the only sister to Lin, and I had nothing to do with the attack last night."

Aiwei turns to Lin, "She is telling the truth."

Korra sighs in frustration, "This is a waste of time! Just bring in the next guard!"

The next guard walks in and sits down.

"Give me your name and tell me where you are from."

"I'm Hong Li. I was born and raised here in Zaofu."

"Do you have any knowledge of the people who tried to kidnap Avatar Aang?"

"No."

Aiwei stiffens and leans forward, "Did you help the attackers enter Zaofu last night?"

"No, of course not."

"You're lying."

"What?! No, I'm not!"

Suyin walks and storms up to him, "How did they get in and out?" She grabs him by the armor and pulls him out of the chair and slams him against the wall, "Where are they now?"

"I don't know! I'm telling you, I didn't help them!"

"You're a traitor to the entire clan!"

"I suggest we search his place." Aiwei said.

Hong Li's eyes widen and quiver with fright.

Both Team Avatar's go to an apartment complex, which is Hong Li's house, to search for evidence. Bolin walks to the kitchen and opens the oven before closing it in disappointment. He stands up and opens a small cupboard above.

"Something feels off." Zuko whispers to Aang as the search through drawers.

"I agree." Aang replied, "Hong Li seems a little young, and it looks like he lives a good life. He has no reason to betray Suyin like that."

Mako picks up a small written note, "I got something!"

"What?" Bolin said with a mouth full of cookies.

Bolin and Sokka quickly puts away the cookie jar and starts to eat as everyone walks over to Mako.

"It looks like it's from them. 'Team assembled. Ready to rendezvous.'"

Asami hands Aiwei a book, "And look at this."

Aiwei takes the book and opens it as Mako leans over to look, "These are the guards' logbooks. All their schedules and routes are in here."

"That guard knows everything." She closes the book, "We have to get him to talk."

"Let's go confront him with this evidence right now." Mako said.

"No." Aiwei says, "Let's give him a little time to sweat it out. He will talk eventually."

Aiwei walks away.

Mako who forms a slightly suspicious look on his face as he watches the truth seer leave. Then he notices Aang whisper something into Toph's ear. The earthbender nods determinedly before leaving the group.

The rest of Team Avatar leaves and spends their time checking out the cooled down moat from last night. Naga walks around, sniffing the rocks. A few Zaofu guards watch over the crime scene.

"I don't understand why we're not talking to that guard right now." Mako says, "Every minute we waste here, those guys get further away. I mean, how does a random guard get involved with a group of super criminals anyway?"

"What do you mean?" Asami asked.

"That guard is only eighteen years old and has lived in Zaofu his entire life. Zaheer and his gang have been in prison for more than thirteen years."

"I don't know, but we all saw the evidence. It's pretty overwhelming." Korra says.

Varrick pops up from inside a hole, surprising the gang, "Maybe a little too overwhelming?"

"Hey, Varrick. What are you doing here?" Bolin asks.

"Collecting pumice stones with Zhu Li. That lavabender did a lot of damage, but he makes a nice exfoliating rock, and when you got callouses like mine, you take all the pumice stones you can get your hands on. Or in my case, feet."

Varrick laughs, as Zhu Li rubs a stone against his foot, to Team Avatar's disgust.

"What were you saying about the evidence?" Mako asked.

"I was saying that I can smell a conspiracy when I see one. Look, if I was trying to set someone up, I would tell everyone he's guilty and then plant the evidence in his apartment as proof."

"Oh, you mean exactly like what you did to me?"

"Yes, just like that! Remember how great that worked? Well, not for you."

"You're right. All the evidence points to this guard, but maybe he's just the fallback."

"But for who?" Bolin asked.

Mako looked at Aang, "What did you tell Toph back at the apartment?"

"Zuko and I were a little suspicious of everything, so I had Toph go question Hong Li and Aiwei." Aang replied, "If anyone can catch a lier, she can."

"You think Aiwei did it?" Asami asked.

"He was unusually adament that he do the interrogation and not Toph." Sokka said.

"While Toph is questioning Aiwei, we should go check out his house." Zuko suggested.

The others agreed and made their way to Aiwei's house. When there, Bolin peeks into the window.

"He's not home. Or he's hiding in there." Bolin gasps, "Or he's invisible." Mako looks at him very skeptically, "Probably just not home."

"Toph must be questioning him now then." Aang said.

"We have to get in there and find some evidence that links Aiwei to Zaheer, otherwise Su won't believe us." Mako said.

Team Avatar walks in and begins to search. Asami flips through a book on a table, "It's just an empty book."

Bolin gains interest in a jar on Aiwei's bookshelf, "Hmm, it's like a desert on a jar."

"Bolin, put that back!" Mako says, "We don't want Aiwei to know we were in here if we can't find anything." Bolin moves to put the jar back, but has forgotten where it was, "You forgot where it goes, didn't you?"

Mako puts the jar back on its shelf a few inches from where it originally was. He moves onto the end of the bookshelf, as he sees some marks on the floor, "These look like scuff marks. I think this bookshelf slides open." He slides the shelf aside to reveal a cellar.

"What do you think is down there?" Korra asked.

"Could be a storage cellar." Bolin said.

"Or it could be how Zaheer got in and out."

"Aiwei's coming back!" Asami said, "Quick."

The group run off of the stairs and slide the bookshelf back where it was, as Aiwei enters.

"What are doing in my house?" Aiwei asked, "You are trespassing on the property of one of the highest-ranked officials in the city. You'd better have a good explanation."

"We do. We do." Bolin said, "We actually knocked on your front door and we thought we heard you say, 'Come in, I'm in the bathroom!'" The room fell silent as Bolin changes back to his normal voice, "I don't even know why I'm saying that. You know I'm lying, and you don't even sound like that."

"We came here because things weren't adding up, and we thought you might have some answers." Korra says.

"So I assume that's why you sent Toph to interrogate me?" Aiwei said, looking at Aang.

Aang gives him a small glare, "Excuse me if I'm a little skeptical. I was almost captured last night."

Aiwei gestures to his couch, "Sit. If you want to talk, let's talk over some tea." He pours green tea into a cup, "Now, what is not adding up exactly? Hong Li was clearly lying and we found evidence in his apartment."

"But don't you think it's weird how young he is? How did he ever get mixed up with this group?" Mako asked.

Aiwei walks toward the bookshelf, "Perhaps through a relative, or maybe he was bribed. We will find out those answers in time. But if wasn't him, who do you think it was?"

"We don't know." Asami replied.

Aiwei moves the jar back to its original spot, "You don't think I had something to do with this, do you?"

"We're just looking for answers." Korra said.

"And you think you've found something, don't you?" He notices the bookshelf has been moved. Pauses as Team Avatar looks at each other nervously, "You have no idea what is coming for you, Avatar."

Aiwei metalbends his stairs upward. Mako firebends at the new wall, but it has no effect. Korra metalbends into the wall, but only makes a small rupture.

"Come on, he's getting away!" Mako says.

"I'm still a little new at this, so back off!" Korra replies. She manages to break through the wall, and the gang run to the cellar and open the door, only to find a bomb, which promptly goes off, but Korra airbends to protect herself and her allies from the impact.

"He's gone." Mako says.

Korra sees a small opening nearly covered by debris, "Look, he must've escaped through there! Help me clear it out."

Bolin, Korra and Aang do so with earthbending to reveal a tunnel entrance.

"A secret tunnel." Sokka said as Lin, Suyin and Toph run into the room.

"What happened?" Lin asked, "We heard an explosion."

"Where's Aiwei?" Suyin asked.

"Your trusted adviser is the one who betrayed us. He was lying about the guard." Korra replied.

"What? No!"

"I tried telling you." Toph said.

"We confronted him and he escaped through here." Aang points to the tunnel.

Lin uses seismic sense on the tunnel, "He must have collapsed the tunnel behind him."

"And he rigged an explosion to destroy any evidence that might have been here." Mako said.

"This is where Zaheer got in and out. Aiwei was the traitor." Korra added.

"I... trusted him." Suyin said sadly.

Kuvira runs in, "Is everyone okay?"

"Aiwei is a fugitive." Lin replies, "Get all available guards to search the mountainside, and find out where this tunnel exits immediately!"

Kuvira obeys, and Lin walks over to comfort her sister.

----

The Beifong sisters and Team Avatar were sitting in Suyin's office when Kuvira runs to the door

"What did you find?" Lin asks.

"We located the end of the tunnel, but there's no sign of him. Just some fresh tire tracks."

"He had an escape plan all ready to go." Mako said as Kuvira left.

"I trusted him with my life. I thought we were family, but it was all a lie." Suyin said.

"Whoever these guys are, they're more powerful than we thought, and more dangerous." Mako said.

"That's why we have to find them." Aang said determinedly, "We're holding off our search for airbenders to look for Aiwei."

"Aang, are you sure?" Korra asked, "You guys can continue looking for airbenders while we hunt down Aiwei."

"No, as long as these guys are out there, no one is safe. Especially the people I care about. I'm done running from people trying to capture me, it's time I face them head on."

Korra nodded, "Then Naga can track his scent."

"And I bet if we find Aiwei, we'll find Zaheer." Asami said.

"No! We're not hunting this group." Lin said, "There could be other secret agents in other parts of the world looking for you right now! I'm taking you both back to Republic City, where I can protect you."

"If I wasn't safe here, then I'm not safe anywhere." Aang replied.

"Aang is right. We have to stop them!" Korra added.

"It's too dangerous! You are not going!"

"Stop trying to protect me! I'm the Avatar. This is my job!"

"Don't lecture me about jobs!"

"Enough! Korra, Aang, listen to Lin." Suyin said.

"But... they..."

"Please. Lin's only looking out for you. I promise you, Aiwei and everyone he's working with will be brought to justice."

"Fine, if you really think it's best."

"I do."

"Thank you, Su."

"Everyone should get some rest tonight. I'll have my people prep your airship and you can leave first thing in the morning."

-----

At Team Avatar's apartment, the teens sulk around, disappointed that they have to leave. Suddenly, there's a knock at the door. Korra opens it to find Suyin.

"Su."

"You really think Naga could track Aiwei?" Suyin asked.

"Definitely."

"Then, here." She hands Korra keys, "There's a jeep packed with supplies on the east gate. It's all gassed up and ready to go. Appa is also waiting."

"What? Why?"

"Because I want you to hunt down Aiwei and bring him back to me."

"But you said-" Bolin started

"I said what Lin wanted to hear and I bought you guys some time. Go. I'll deal with Lin in the morning."

"Let's get this guy!" Korra hugs Suyin, "Thanks."
