What is next for the walking dead?

Glenn is alive. Ron has a loaded gun. The walls have fallen. Everything is in place for a dramatic midseason finale next week. 

Having read the comics, it's not too difficult to have a handful of predictions for 608, titled "Start to Finish," based on how things went down on paper.

First of all, that herd of walkers is getting into Alexandria. This story arc in the comics is called No Way Out and it is one of The Walking Dead's deadliest. The walls falling unleashes a series of events which cost us many of our beloved characters. in the comicbook When the walls fall, Tobin is devoured. Morgan is bit and has his arm cut off shortly afterwards. He eventually succumbs to the wound and is put down by Michonne but not before Michonne opens up and shows some real emotion. 

Rick and Jessie try to make it out of the Safe-Zone but Ron's panic causes him to get bit and Jessie tries to rescue him. You guessed, she gets eaten as well, but holds onto Carl's hand as she tries to pull herself from the herd. Rick, not willing to let Carl get pulled into the zombie chow, cuts off Jessie's hand and leaves her behind. 

Shortly after Jessie's death, the Safe-Zone leader and comic book equivalent to Deanna, Douglas Monroe, starts firing his gun, trying to take down walkers. He is swarmed and devoured and as he falls, fires his gun in every direction. One bullet strikes Carl in the eye and blows a chunk of his face off. 

Rick's band of survivors end up fighting off the rest of the herd and Carl is rushed to Denise's infirmary. As he lays on the infirmary bed, Rick pleads with him, saying he sees a hope for a new world with organization and society and begs for Carl to wake up and see it with him.
