We've already seen one way to deal with fear, with Tori's explanation of her tattoo (spoiler alert: it's a symbol); and here's Four offering us another way to deal with a fear, which is to act like it doesn't bother you (and bring a change of pants). It's an important aspect of Four's character: he's not fearless, he's just fear-resistant.

Competition doesn't mix so well with friendship in this book, even when the friends are on the same side. Here, Tris and Christina are on the same team in a paintball game. But when Christina grabs the flag, Tris—who came up with the plan—feels left out. Yes, Tris joins in the shouting and running, but at the end of the paragraph, she's still "off to the side."

As Tris notes, the Dauntless are very interested in pride (13.9). So they don't reward winning a competition with a stuffed animal or kewpie doll. The real prize of competition is bragging rights and proving that you're better than other people. That sure sounds like a nice community to live in said no one ever.
