Summary[]
Angela Bishop visits Miriam and says she's looking for Johnny Bullhorn, who is on a list of people that she needs to speak with about Matt Caldwell. Miriam insists that Johnny couldn't have hurt the Caldwell kid because he's been sick with the flu and she’s been taking care of him all week.
Dexter debates with Deb in his head about Kurt Caldwell’s true intentions behind saying his son is alive. Deb theorizes it’s because he wants Angela to close the case so that he can kill Johnny Bullhorn later on, believing that Johnny murdered Matt for shooting the deer. Or she thinks Kurt might find his way to the real killer - Dexter.
