I am a little confused maybe you can help.
I don't know if i missed something or it will become clear later. When they go to drop Randall off they find those two policemen walkers but they didn't have any bites but they did have scratches ok i get that.
Then Shane broke Randall's neck and within a couple of hours he comes back as a walker and attacks Darrel and Glen. Then Ric kills Shane and he comes back almost instantly but neither of them where bitten?
Whats going on?
