Benny and Tom's confrontation in the Ruin after seeing a gang of bounty hunters torturing zoms almost brings them to blows. They make up almost immediately after.
"I'm sorry," they both said.
They stared at each other.
Benny smiled.
Tom's smile was slower in coming.
"You're a total pain in my butt, little brother."
"You're a world class jerk."
Tom tells Benny that he's always made sure that Jessie and Nix, who are always struggling for money, never go hungry, and makes Benny promise not to tell Nix this. Jessie tries to make it up to him in her own way by constantly sending him baked goods.
George Goldman's story. Despite not being related to them, he devotes years of his life to raising Lilah and Annie, getting them clothes and books, teaching them how to read and write and defend themselves, and becoming the only parental figure the two girls will ever know. Small wonder he completely loses his mind when they're stolen from him by bounty hunters.
After years of resenting his brother and spending most of the book calling his brother a coward, this is Benny's reaction when Charlie calls Tom "nothing but a fool and a coward": punching the much bigger bounty hunter in the face and shouting: "My brother is not a coward!"
Dust and Decay
Tom's comment on loneliness, which, while doubling as a Funny moment, really gives an insight into how much even the tough, lone wolf bounty hunter loves his only living family member.
Tom: I can handle loneliness, but I don't like it. Every time I was out on a long job I even looked forward to coming home to you. An ugly, smelly, bratty little brother.
Chong's absolute guilt and distress that Nix is going to wind up with a massive facial scar because of him. He argues that she's beautiful and she should always be beautiful, to which Benny and Tom quickly respond that Nix is always going to be beautiful, scar or no scar.
Flesh and Bone
Lilah, whose only understanding of love and romance comes from novels, convinces herself she's in love with Tom. She tells him so, and Tom turns her down, without any trace of awkwardness, in the gentlest, sweetest way possible.
Tom: Lilah, you are my friend. You're a very pretty girl, no doubt about that. You are strong, and intelligent, and lovely, and you care about people. All of those are amazing qualities. If I was Benny's age, I have no doubt that I would be one of a hundred boys who would fall head over heels for you.
It takes, and Lilah gets over Tom, and they stay friends.
She let go of her desire for Tom, though in a different way she loved him more than ever. She always would.
