Some of the following quotes highlight Percy Jackson’s decisions to risk his life for his friends; others indicate a propensity to put others ahead of himself.
Page 9 — Percy lashes out at Nancy because of her actions against his friend Grover.

I don’t remember touching her, but the next thing I knew, Nancy was sitting on her butt in the fountain, screaming, “Percy pushed me!”

Page 36 — Percy is talking to his mother, trying to prevent her from feeling bad about his expulsion. He’s not risking his life, but he is putting another first.

For her sake, I tried to sound upbeat about my last days at Yancy Academy.

Page 53 — Percy refuses to leave Grover and his mom and run to safety, even though she clearly tells him to.

”No!” I shouted. “You are coming with me. Help me carry Grover.”

Page 57-58 — Percy attracts the beast’s attention and risks his life to save Grover.

The monster hunched over, snuffling my best friend, as if he were about to lift Grover up and make him dissolve too.
I couldn’t allow that.
I stripped off my red jacket.
“Hey!” I screamed, waving the jacket, running to one side of the monster. “Hey, stupid! Ground beef!”

Page 169-170 — Percy escapes the Furies coming to the back of the bus, but that leaves Grover and Annabeth trapped. Instead of keeping quiet and escaping, he helps his friends.

What I did next was so impulsive and dangerous I should’ve been named ADHD poster child of the year. . . .
I looked at the open doorway. I was free to go, but I couldn’t leave my friends. I took off the invisible cap.

Page 216 — Percy battles Echidna and her Chimera to protect the humans who happen to be trapped in the room with him.

I ended up next to the family and the park ranger, who were all screaming now, trying to pry open the emergency exit doors.
I couldn’t let them get hurt. I uncapped my sword, ran to the other side of the deck, and yelled, “Hey Chihuahua!” The Chimera turned faster than I would’ve thought possible.

Page 264 — Percy decides to free the animals trapped by smugglers, in spite of the fact that it will both slow them down and put them at risk of discovery.

“We’ve got to free them!” Grover said. He and Annabeth both looked at me, waiting for my lead.

Page 317 — Percy and Annabeth catch Grover and work together to prevent him from falling into the pit.

He was ten feet from the edge of the pit when we caught him and hauled him back up the slope. The other winged shoe tugged itself off, circled around us angrily and kicked our heads in protest before flying off in the chasm to join its twin.

Page 329 — Percy gives the passes out of the Underworld to his two friends, when his greatest desire is to save his mom.

“I know what to do,” I said. “Take these.”
I handed them each a pearl.

Page 361 — Percy steps in to fight his stepfather for hurting his mother.

For the first time, I realized something. Gabe had hit my mother. I didn’t know when, or how much. But I was sure he’d done it. Maybe it had been going on for years, when I wasn’t around.
A balloon of anger started expanding in my chest. I came toward Gabe, instinctively taking my pen out of my pocket.
