Not yet. It is clear from The Talking Dead that he will have a major role with “unfinished business” in the next episode before he dies.
If Coral really dies, this makes no sense.
The whole story revolves around him and he is the one who is telling it, as an old man.
Stupid plot change.
I wonder if they’re not giving him a couple years off, so to speak, for the college gig.
The series has already been renewed for several more seasons so it’s possible he might ‘shockingly return’, in the future.
[who in Hell leaves TWD for a college stint??]
