Quote 1
"[…] I want you all to do something. Since we have a few days before the paper has to come out. Try to find out everything you can about what kids think of The Wave." (9.48)
Laurie suspects The Wave is bad, but she's trying to be a responsible journalist. She knows that they need to investigate before they can give the public the truth about what's going on.
Quote 2
Laurie squeezed his hand. "You weren't dumb, David, just idealistic. I mean, there were good things about The Wave. It couldn't be all bad, or no one would have joined in the first place. It's just that they don't see what's bad about it. They think it makes you equal, but they don't understand that it robs you of your right to be independent." (16.39)
Laurie's right: The Wave did have some positive aspects. And hey, if the group had had a clear-cut, positive goal, it might not have turned so ugly. Why does she communicate this to David at this moment? Is she trying to make him feel better, or does she truly believe this?
Quote 3
"[…] I want you all to do something. Since we have a few days before the paper has to come out. Try to find out everything you can about what kids think of The Wave." (9.48)
Laurie stays true to her identity as a journalist: she remains unbiased and just tries to find out the <em>truth</em>.
Quote 4
"Amy, I'm serious. The Wave is hurting people. And everyone is going along with it like a flock of sheep. I can't believe that after reading this you'd still be part of it. Don't you see what The Wave is? It's everybody forgetting who they are." (14.7)
Evidence that The Wave might be causing physical violence convinces Laurie that she has a responsibility to warn people about it. She's also concerned about what could be considered psychological violence: she thinks The Wave is forcing people to give up their personal identities in order to be part of the group.
