Chapter 1 : Season 2: "Rose"

The Mute Salvatore.

The youngest Salvatore has never spoken a word. She had never cried as a baby, never screamed when she was scared nor did she ever laugh.

Damon and Stefan had learnt sign language at a young age to communicate with their little sister who still communicate much with sign but more her looks and actions.

So how does the mute Salvatore help her brothers and Elena against the originals?

How does the youngest Salvatore already know the originals?

Will she remain The Mute Salvatore?
