for season 2 and 3. But she did have a lot of time and a couple of important story arcs for season 4 and the first half of season 5. Beth actually had a lot of fans believe it or not; her death had a pretty big impact on TWD community. There were fans petitioning to bring her back on the show (as stupid as it sounds) and other fans really wanted her and Darryl to have a romantic relationship. Hell, she had about 3 episodes or so that solely focused on her story arc.

Tyrese had a smaller role when he first appeared on the show in Season 3 but they really fleshed out his character in season 4 and the first half of Season 5. He also had a couple of episodes solely focused on his story arc.

With background characters like Bob, Deanna, Denise, Jessie, they played an important role for a handful of episodes, but they would never dedicate a full episode for them and nobody really gave a shit if they lived or died.

We'll see what happens in the season finale but I do agree with everyone that it has to be a core member of the survivors to mirror the comic death and to have that gut crushing impact on the fans.
