So, watch this whole trailer, but pay special attention to what happens around :28.
That is Beth, Hershel’s angelic blonde daughter, giving Rick Grimes a tender peck on the cheek. Now, this might just be in the midst of a group farewell, but am I crazy to see something more? Beth seems to be giving Rick a look, and Rick is giving Beth a look. Maybe I’m just crazy. Although Beth has been expressing some vague interest in Rick’s son, Carl. Those Grimes boys, they’re magnetic!
