Fans will continue to push the 'Caryl' train until either of the two potential participants is inevitably given a cruel send-off. Daryl is the pièce de résistance of the series, with an enormous fanbase dedicated to his TV-unique character. He is the creators' individual stamp on the story and one of the main men, despite not featuring in the comic book source material.
He's here taking to Carl (has anyone actually seen that happen before?) when Carol approaches. She confronts Daryl, stands firm, and puts him in his place. This is a time when both characters are growing: Carol from a vulnerable mother into the strong, hardened schemer we see today, and Daryl is going through the journey from outcast to a true member of the group.
