A bit sad, I know, sorry. But I do like Tahnorra so I couldn't resist! Hope you enjoy! This can also be found on my tumblr, which there is a link for on my info page

She ran. She ran faster than she ever had before. Korra hadn't even given a second thought to it. She dropped everything, and ran. She had gotten alone by claiming she was sick, and as Tenzin and his family, and Mako, Bolin and Asami ate dinner, she fled. Getting across the water had been the first step, and had been easy. But now that she was on dry land, only her feet carrying her, her mind was blank. She ran through the streets of Republic City, past the faces of the citizens on the streets, whose voices followed her. "Is that the Avatar?", "What is she doing here?", "Good for nothing!", "You're supposed to protect us! Why aren't you doing your job!?". The questions haunted her, causing her to run faster.
She ran till her chest was heavy, and her throat was tight. She ran as the shining buildings of Republic City gave way into the not-so-glamorous suburbs, as the streetlights became farther and farther apart, until there were none at all. It was only then, did she slow down. In an ally, where no people were. She could be alone with her thoughts, and the voices as they rang through her head. Korra slid down against the brick wall, collapsing and resting her head between her knees. Her chest rose up and down quickly, struggling to get enough air.
Soon enough, her panting gave way to heaving, and heaving gave way to sobs, sobs that shook her whole body. She hugged herself, the only comfort available to her. And as tears streamed down her face, and as she struggled to breathe, she realized something. She wasn't strong enough. She wasn't. To save those innocent people of Republic City, of the world. She just didn't have that strength. Spirits, she couldn't even face Amon without knowing she would sooner or later fail. She wasn't the Avatar that the public deserved. She couldn't live up to what Aang had been.
"Korra? Is that you?". She knew that voice, the voice that had lost its spark. She couldn't deal with him right now, couldn't face him. She hadn't been able to save him. He was a prime example of why she wasn't cut out to be the Avatar. The sobs came harder, and her throat tightened up. "Korra, Korra, hey! Snap out of it!" Korra ignored Tahno as he placed his hands on her shoulders, and continued to cry. "Korra, what's wrong? C'mon talk to me." His voice was softer, but she still couldn't face him. Instead, she just cried. Korra didn't resist like she normally would have, as he pulled her closer, into his arms.
"Shh, Shh. It's okay." Tahno murmured, and Korra continued to cry.
