“She’s more… mature,” Susan said quietly. “She thinks about things instead of simply reacting. Gina’s impulsive. And with the pressure she’s under—the same pressure you’re all under—she might not make the best decisions.”
--- uhhh. everyone thinks. it's physically impossible to "simply react". ur brain processes inputs, figures out answer. sometimes it's fast, but you always think, and part of that thought process is: you decide how long to take for a given choice. so not only does gina think about what to do, she chooses to choose quickly. this is not being "immature" it's being immoral (she does it recklessly, making many mistakes). and she doesn't do this b/c she's under pressure. sure, that doesn't help, but she is responsible.
