Use your words Andrea
The Walking Dead is clearly a world where folks don't talk about nuthin'. It makes sense that the devious or emotionally crippled characters would keep thoughts to themselves. Andrea is one of those characters that famously irritates a fair portion of the audience. I think the key issue is that Andrea rarely asks the questions that are pertinent to her situation. Her continued ignorance feels like a plot contrivance and so it grates on the nerves. That said, I feel like the actress is leaving her expression open to all of the thoughts Andrea would logically be considering. Sadly she isn't allowed to articulate those thoughts and ends up looking vaguely dazzled as a result.
