Lin was indeed less than happy to see Mako walk into the station helping Taimu carry the now awake and bound Red Lotus spy.

"What is he doing here? And why isn't he in handcuffs?"

Mako helped Taimu seat their prisoner before answering. "Sorry chief, but we weren't having any luck finding Korra on our own, and I thought that he might have some idea what had happened to her."

"So you compromised our ongoing efforts to bring this guy in, and involved him in an ongoing investigation?"

Before Mako could answer, Taimu spoke up. "Recognize this?"

Lin caught the necklace Taimu tossed her, glanced at it, and then took a second, longer look as Taimu continued speaking. "Our new friend here was wearing while he watched us find a pool of what seems to be Korra's blood. You don't like me, fine. I've given you no reason to like me. But if you want to save Korra, you need to get focused."

"Regardless of the situation with Korra, you're still a criminal who's shown no remorse for his actions."

Taimu shrugged. "Fine. Then you can arrest me. After we find Korra."

Lin leaned in. "You are in no position to bargain."

The Red Lotus prisoner suddenly surged to his feet, knocking Mako down in his rush for the door.

Abruptly Taimu was in front of the fleeing spy, slamming into him and knocking him to the floor.

A moment later Lin's cables reached the spy and snaked around him.

Lin was about to pull the fugitive back when someone stepped onto her cables.

Lin looked up to meet Taimu's steely gaze. "It seems I am in an excellent position to bargain."

Lin glared for a moment, then her gaze softened slightly. "You're actually worried."

Taimu stepped off the cable and helped Mako up. "Raava is in the hands of a group that has made a determined effort to kill her before. Shijan is very concerned. I don't mess around when he's concerned."

"Alright. I'll let you help us find her. But once we find Korra, I expect you to follow through on your promise."

Taimu nodded. "Agreed. Now, please, get some answers out of this guy."

"I know how do do my job." Lin snapped, using the cables to haul the spy to his feet before sending the cables back to their holsters and grabbing the spy's arm. "Let's go."

As Lin escorted the prisoner towards one of the interrogation rooms, Asami turned to Taimu. "I'm a little surprised you didn't insist on going with her."

Taimu shook his head. "Chief Beifong would never have allowed it. Besides, I need the time to prepare."

"Prepare for what?" Mako asked.

Taimu met and held Mako's gaze. "For getting the information we need from the spy if the chief fails."

"She won't like that."

"She can take it out on my prison time. I have one job; ensure Raava continues. I intend to do my job."

Mako opened, his mouth, then hesitated. "You know, this is the first time I've seen you be serious."

Taimu smiled a smile that contained neither humor nor warmth. "You've only seen me when I'm off duty. Now, please, I need some quite to prepare myself."
