I don't particularly know why this section is titled Eden but it takes place once Titus and his crew have become hospitalized for getting the transmission to the feed about the demise of society. They do not have connection to the feed at this point because that man messed it up. While stuck in the hospital for that period of time they do things to pass the time like mess with the medical supplies and make games out of them. Even though the whole group of people did not enjoy their time on the moon they seemed to have a better time in the hospital. The difference between this section and the rest of them is that they were much shorter. It was probably due to the fact that they were not exposed to the feed and could only be exposed to what they were surrounded by and not the feed. The fad-following girls really missed the feed. They pretty much depended on it for every decision they made. A prime example is on page 52 when Loga went to visit them and she went into the bathroom to change her hairstyle because popular hairdo was different and then the girls did the same thing because they saw that it was the current style. They relied so much on the way that the feed told them to dress and cut their hair that their disconnection from the feed was much worse.
The part that stood out to me the most was the attachment to electrical devices that many people have. They feel as if they are not connected to the world if they do not get on the internet or have their phone right beside them. It may be that we are so dependent on these things to keep up with people instead of having an actual conversation or encounter with them. I have personally seen how our minds grow accustomed so quickly to the things we do and then there is a greater need for them that it is almost impossible to not have it. Sadly, many people are like Calista and Quendy who do not try to be their own person but follow whatever the feed tells them is the popular thing to do. Supposedly this society is even more focused on the concept of individualism and being yourself, independent but this quality of following the trending topics is displaying quite the opposite in the practice.
