"Is this the place where they took him?" Korra asked looking around. 

"Yes, this was the alley way witness' reported." Lin said. 

Cops were circling the area. People were taking lots of pictures. Naga sniffed around. 

"I hope we will be able to find him." Asami said. 

She looked all sad, and she looked like she was going to cry. Korra put her hand on her shoulder. 

"We'll find him. I promise." Korra smiled. 

"We have to." Bolin said.

Asami smiled. 

"I saw what happened and I know who did this." An old man said walking forward. 

"Tell us what you know." Lin said. 

"They are three men. Three men who've I've come across a couple years back. They are monsters. They are called the Dread Doctors." The man said. 

"Dread Doctors?" Bolin asked shivering. 

"Yes. They experiment on people. But recently they've been pushing for the Beast of Fue." He said. 

"Do you know what the word means?" Lin asked. 

"No, but I know someone who does. Go east there is a Guru who knows that word. Guru Patik." He said. 

"Guru Patik?" Tenzin asked. 

"Yes." He said. 

"Do you know him?" Korra asked. 

"He was a teacher to my father." Tenzin said. 

"Aang." Korra said. 

"Yes." Tenzin said. 

"Do you know where they're keeping my brother?" Bolin asked.

"No, but I do know you have to find him fast. The Dread Doctors will do terrible things to him, if not already." The old man said.
