Percy Jackson is a hot tempered young man. “I am going to kill her, I mumbled.”  First of all,(on page3) he stands up for his friend, Grover, when he was boiled by Nancy. He was really angry, he does not want his friend to get boiled, he was trying really hard to keep cool and calm. “I turned so he couldn’t read my expression, and started getting ready for bed.” Secondly, (on page21) he was really angry, because he heard he’s leaving Yancy Academy. “Fine, I said, and threw the money on the table, I hope you lose.” He was very angry, because his stepfather didn’t even say anything like Nice to see you again. Instead, he asked Percy for cash. Overall, this is quit clear that Percy is a hot temper young man.
