Well I wouldn’t be that cheesy and let Glenn die that way. I would let him survive under Nicholas and it be Nicholas guts they are eating but let nicholas thanking him for the second chance be what breaks Glenn and causes his death in some other way. More interesting that way. In my opinion anyway. Nicholas taking his own life not wanting to survive after he left so many others to die then Glenn going overboard saving him then him taking an easy headshot would end Glenn emotionally. That’s what I would write.
I like the way you think and agree 100%.
