After The Red Lotus tried to kill Korra and end the avatar cycle by poisoning her with mercury she’s been very quiet. She’s been living with her parents Tonraq and Senna in the northern water tribe since she’s still paralyzed from the waist down and in physical therapy. She hasn’t been sending letters to Asami,Bolin,Mako, Tenzin or even his kids, only you. She sat at her desk in a dimly lit room trying to think of what to write to you. “think.. think think..!” She was getting more agitated at her inability to think of what to write, normally she couldn’t shut up but now she just couldn’t think of what to say or in this case write.
