Answer :
Sally Jackson. Percy's mom loves him more than anything. She sees right through to his heart and can detect his mood better than any mood ring. When he first sees her after being away at boarding school for sixth grade, he tells us, "when she looks at me, it's like she's seeing all of the good things about me, none of the bad"
Percy feels relieved that his mother is alive and ok but angered at the person who did this.
