It seems the foreshadowing is obvious on what the season finale cliffhanger will be.
Consider the first encounter with the Negan bunch when the group was informed that Negan's people usually beat someone to death right off the bat.
Then Glenn sees the pictures on the wall of people who were beaten so badly their faces were obliterated, just hair and clothes left to identify them.
Negan's bunch has Maggie. They have good reason to want to destroy all of Rick's group now after the attack and slaughter at their compound.
In the comics, Glenn is beaten to death in front of Maggie.
However, Glenn has an uncanny knack for surviving the most incredible circumstances.
Then, there is Abraham making a choice between the women.
The season finale cliffhanger is going to be a body with black or dark hair, face obliterated, wearing almost recognizable clothing, displayed face up for the viewing audience to see and speculate all intermission long on who the body belonged to.
Is it Glenn? Or, is it Daryl? Or, is it the chick Abraham forsook? Or, is it Maggie? Or, is it Carl? Or, is it the doctor's girlfriend? Or, is it the quack scientist who didn't really have a cure that just learned how to fight?
