Bloodletting is the second episode The Walking Dead season 2. The episode begins with a flash back scene when Rick was shot. It shows how Lori having some issues with Rick and their marriage somehow on the rocks. Shane arrives telling her that Rick is in surgery after being shot. Lori then tells Shane what happened to her father.
Back to present time, Rick and Shane is shown running with another man, later identified as Otis, the man who accidentally shot Carl. (Too bad they did not get the deer). Otis leads them to the Hershel Greene's farm who turns out to be a doctor. Carl was immediately attended to and fortunate enough that his father shares the same blood type.
The other group who is heading back to the highway even though hearing the gun shot decided to continue looking for Sophia. Dale noticed that T-Dog may be having blood infection from the cut he had from the previous episode. They tried searching the vehicles for some antibiotics.
