According to EW, Connie is called a “seasoned survivor” who is an expert at utilizing her senses beyond hearing in order to grasp situations, other people and potentially problems.
In its current state, the first character description for The Walking Dead’s TV Connie doesn’t go very far beyond what is already made clear by the casting choice.
Lauren Ridloff doesn’t sound like she’ll be a permanent fixture on the show, as it’s reported she will be involved for a multi-episode arc.
It’s specifically noted that, as a deaf woman, Connie uses American Sign Language to communicate, which is something that almost definitely comes in handy during intense circumstances where silence is key to remaining undetected.
