Streams of Silence (UA fanfic)

Number 8, or Khiona, was always considered as an outcast, even more than Vanya Hargreeves. She only joined the academy when she was 11. She randomly went silent when she turned 12. Everybody saw her as a freak, or outcast. Except for 3 people. Well, one of them is her adoptive robot mother, one of them is a homicidal octopus, and the other was, well, Five Hargreeves.

Her reclusive nature only grows worse with the absence of Five, who disappeared on the 11th of Novermber, 2002. She dives into an unrecoverable state with the death of Ben, who died in 2006.

However, with the return of Five, she seems to evolve into something... entirely different.
