Comic Book Spoilers. What might happen is Hershel will get hit in the back of the head and will 'black out' by Martinez's baseball bat. They will bring Hershel back to Woodbury and keep him as prisoner. Rick and Daryl will escape. Andrea goes back to woodbury with the govener. Tyreese and Sasha will find Hershel and try to escape with him. I think Andrea, Tyreese, Sasha, Milton, Dr.Stevens, Hershel, Karen, and Noah will all TRY to escape. Allen will be caught in between Ben/Woodbury and the prison. Also I think Hershel can have a good chance of dieing. 

I think Pale Horse was supposed to be Hershel.

Can this happen?

Will Hershel die in this episode?
