Do you think Lee died????
Personally I think Lee lives. Yea he was bit ,but he cut it off and after that he was fine. Until he was shot trying to save Clem. , but lets think here if your in that type of world you have no medical equipment , so of course he will pass out at the end. He lost a lot of blood , and Molly is still out there and she was a scavenger so maybe she found some medical supples so maybe she found him and saved him.
