The death of Glenn was in a general one expected - in the original comics of Robert Kirkman, this character was also killed by Nigan, and the producers of the "walking dead" shortly before the release of the 7 seasons have already warned that from now on, they will try to stick to the storynger from the comic instead of radically .
Jeffrey Dean Morgan, who played Nigan in the "walking dead men", in the death of Glenna Vinit Daryl (Norman Ridus), who did not cope with the emotions after the murder of Abraham and hit Nigan - for which he decided to take revenge, having deprived the group of Rica another participant. "If it were not for Daryl, Glenn would stay alive," said Morgan on Talking Dead talk show.
Abraham in the "walking dead" lasted long enough for a character included in the group not from the start - for three years. Presumably, his death will be a special motivation for Rick and Eugene, as well as Sasha and Rositis. In the original comics, Abraham leaves the Rositis for the sake of the girl named Holly - and Sasha in comics do not at all. After Abraham kills Dwight in comics, Holly helps Rica to take revenge, participating in the mission to eliminate Nigan and his people - and in the end sacrifices himself. Now, when Abraham in the "walking dead" is no longer, the role of Holly on self-sacrifice will have to repeat either Sasha or Rake (and most likely the first, since Rosita found love with Eugene).
