After episode 3, it's unwise to have emotional attachment to characters. I wanted to see how Telltale would address this in episode 4, and I'd like to know how other people viewed and responded to the emotional impacts in this episode.
I didn't care about the dog or the zombie kid. Both scenes went on too long, especially the burial. I cared about helping Kenny face the kid and shoot him, but otherwise the kid is just another victim in a long list, and the dog is just a way into the house. I felt bad that the kid starved to death, because that is unusually horrible. However, that didn't make it any harder to put the zombie kid down.
I didn't care about Chuck dying. When he said he would take care of himself, I expected him to die. I was glad he got to use a bullet on himself so that he wouldn't come back as a walker.
I didn't care about Brie dying. Her death was graphically disturbing, but otherwise nothing out of the ordinary. I agreed with Vernon that I didn't feel much. I liked that bit of writing, as it shows that Telltale realizes that some people aren't broken up bad about these deaths anymore.
I didn't care about Omid (not) dying. I still expect him to die. Even with meds, he probably just got a temporary reprieve. It's nice that he lived, but not a big deal, since he's still on borrowed time.
I didn't care about the pregnant woman in the video, but I liked that it gave insight into Christa's character. After the description of what Crawford was like, that choice given in the video seemed about what someone would expect.
I expect Lee to die in episode 5, so having him bit isn't that big of a deal.
So, Telltale wrote episode 4 as though people should care about things that don't matter anymore, but it wasn't too bad. Instead, the episode dealt with other things, like finding a boat, getting supplies, meeting new characters, investigating Crawford, and having a few small interactions with the stalker.
As for things that I still care about, episode 4 further developed the relationships in the group, and Lee got to be more of a leader. Probably the best emotional impact came from Lee's protectiveness of Clem, especially Lee's response to Clem's abduction.
