Ares saying he hates his own kids and the worst day of the year is when they visit him makes my heart break for Clarisse more. Clarisse fights so hard for scraps of her father’s attention and Ares sees her as just another nuisance. He doesn’t care about her unless she’s able to serve him. But Clarisse (like Annabeth) thinks she just has to work harder for him to love her. In her mind, it’s all her fault. Which is why she is so angry when little punk Percy strolls in at twelve years old, no training and unclaimed, and immediately defeats the minotaur. In three days hes already got the gods attention and his father claimed him. Of course she’s angry.
