Deadly Silence

Katie McMillan relied on silence and sign language the same way she would rely on air and water. She wasn't mute, she wasn't deaf. She was just so riddled with anxiety and fear 24/7 that she could never bring herself to speak. To hear her speak would be like seeing a quadruple rainbow after finding a six leaf clover. She only ever spoke in dire situations, which was not often.
She was with the group since the very beginning in Atlanta. When the group got together and set up camp at the quarry, she never left Amy's side. She was her only friend there, the only one she would ever whisper to when she needed something.
When everything started going downhill with the new addition of Rick Grimes and the death of Amy, she became more silent and closed off than usual. She no longer had someone to sit with in silence, she no longer had someone to talk to when her anxiety got bad.
She felt alone in the large group.
But maybe someone would be able to bring her out of her shell and make her stronger?
