How we cite our quotes: (Chapter.Paragraph)
Quote #4
I hear a shout and look over my shoulder. A short Erudite boy with red hair pumps his arms as he tries to catch up to the train. An Erudite girl by the door reaches out to grab the boy's hand, straining, but he is too far behind. He falls to his knees next to the tracks as we sail away, and puts his head in his hands.
I feel uneasy. He just failed Dauntless initiation. He is factionless now. It could happen at any moment. (6.15-6)
Tris narrates just about every step of this event, which is very quick (boy fails to get on moving train) but also very serious (boy is now factionless forever and ever). It's a nice reminder of the dangers of Dauntless initiation to Tris (who really doesn't want to be factionless), like when a movie/TV show kills off a minor character so you know that the major ones are never safe. Well, at least this scary moment answers the question of where factionless come from. They're people who failed the initiations.
Quote #5
I wander around the room, looking at the artwork on the walls. These days, the only artists are in Amity. Abnegation sees art as impractical, and its appreciation as time that could be spent serving others, so though I have seen works of art in textbooks, I have never been in a decorated room before. It makes the air feel close and warm, and I could get lost here for hours without noticing. (8.103)
The factions really define everything about a person's life experience, from job choice to recreation to even food choice, like when Tris is surprised by hamburgers (7.37). And here's a great example of that: the Amity are the only faction that does art, while Dauntless art consists of tattoos (and probably sewing eagles onto their jackets).
Quote #6
"When can I go again?" I say. My smile stretches wide enough to show teeth, and when they laugh, I laugh. I think of climbing the stairs with the Abnegation, our feet finding the same rhythm, all of us the same. This isn't like that. We are not the same. But we are, somehow, one. (17.104)
Of course, Abnegation doesn't go zip lining around the city, even if it is a fast way to travel. But what's interesting to us about this event isn't the difference in factions' ideas of fun activities. (Candor probably plays truth or dare but always picks truth.) What interests us is that Tris can a sense of community and togetherness in both actions. So some values are shared from faction to faction.
