Another thought I had: Once Daryl and Richard have had their Mexican stand-off and parted ways, Daryl will be in full Hunter Mode. Target #1: Carol Peletier. I just picture him shouldering his crossbow and going loose on the forest until he spies the cemetery house. I see him standing by the mailbox, marked by Morgan, and looking towards the house, knowing he’ll find Carol inside.
I was also thinking that another reason TPTB are making Carol leave the house to hunt in 7x09 could be to provide fresh tracks for Daryl to find her.
