Here's the thing about Hazel: Almost everyone is obsessed with leaving a mark upon the world. Bequeathing a legacy. Outlasting death. We all want to be remembered. I do, too. That's what bothers me most, is being another unremembered casualty in the ancient and inglorious war against disease.I want to leave a mark.But Van Houten: The marks humans leave are too often scars. You build a hideous minimall or start a coup or try to become a rock star and you think, "They'll remember me now," but (a) they don't remember you, and (b) all you leave behind are more scars. Your coup becomes a dictatorship. Your minimall becomes a lesion....We are like a bunch of dogs squirting on fire hydrants. We poison the groundwater with our toxic piss, marking everything MINE in a ridiculous attempt to survive our deaths. I can't stop pissing on fire hydrants. I know it's silly and useless--epically useless in my current state--but I am an animal like any other.Hazel is different. She walks lightly, old man. She walks lightly upon the earth. Hazel knows the truth: We're as likely to hurt the universe as we are to help it, and we're not likely to do either.People will say it's sad that she leaves a lesser scar, that fewer remember her, that she was loved deeply but not widely. But it's not sad, Van Houten. It's triumphant. It's heroic. Isn't that the real heroism? Like the doctors say: First, do no harm.The real heroes anyway aren't the people doing things; the real heroes are the people NOTICING things, paying attention. The guy who invented the smallpox vaccine didn't actually invent anything. He just noticed that people with cowpox didn't get smallpox....But then I wanted more time so we could fall in love. I got my wish, I suppose. I left my scar....What else? She is so beautiful. You don't get tired of looking at her. You never worry if she is smarter than you: You know she is. She is funny without ever being mean. I love her. I am so lucky to love her, Van Houten. You don't get to choose if you get hurt in this world, old man, but you do have some say in who hurts you. I like my choices. I hope she likes hers.

Pudge/Colonel: "I am sorry that I have not talked to you before. I am not staying for graduation. I leave for Japan tomorrow morning. For a long time, I was mad at you. The way you cut me out of everything hurt me, and so I kept what I knew to myself. But then even after I wasn't mad anymore, I still didn't say anything, and I don't even really know why. Pudge had that kiss, I guess. And I had this secret. You've mostly figured this out, but the truth is that I saw her that night, I'd stayed up late with Lara and some people, and then I was falling asleep and I heard her crying outside my back window. It was like 3:15 that morning, maybe, amd I walked out there and saw her walking through the soccer field. I tried to talk to her, but she was in a hurry. She told me that her mother was dead eight years that day, and that she always put flowers on her mother's grave on the anniversary but she forgot that year. She was out there looking for flowers, but it was too early-too wintry. That's how I knew about January 10. I still have no idea whether it was suicide. She was so sad, and I didn't know what to say or do. I think she counted on me to be the one person who would always say and do the right things to help her, but I couldn"t. I just thought she was looking for flowers. I didn't know she was going to go. She was drunk just trashed drunk, and I really didn't think she would drive or anything. I thought she would just cry herself to sleep and then drive to visit her mom the next day or something. She walked away, and then I heard a car start. I don't know what I was thinking. So I let her go too. And I'm sorry. I know you loved her. It was hard not to." Takumi
