The parts about Steban's mother working as an apartment cleaner and how her struggles as a prole push him to want to live in a better world, the idea that Communism has become a secular religion based around faith that humanity has a future, and of course the bit about the communist who wrote that poem on the last night of his life all hit me pretty hard. Plus, if you make the right choices, you can convince the two to ditch their secret passwords and actually try recruiting a broader range of people - they end up plastering the statue of that dipshit royal with recruitment posters, throwing a middle finger at the cruel old world to start taking steps to build a better one. There's a glimmer of hope that the two become more serious organizers and move on from just having a myopic book club.
