A/N- Written in an effort to sate my Katara/Aang and Toph/Aang shipper at the same time.
Seeing the world through vibrations and sounds is not as wonderful as others thought and she believed before Freedom. There are things not meant to be heard by anyone.
She can feel the tiny whimpers and choked back sobs Sokka hides in the night while whispering some half-forgotten name. She can resoundingly hear the Katara's constant silent worrying.
She feels the quiet opening of eyes and the fear of one bearing the weight of the world.
And she hears his heart beat a little faster when Katara's vibration comes close.
Toph wishes she could see what Aang looked like, sometimes.
