– Damien to Chiara in The Hidden Oracle.
The next day in Woodrow's music lessons, he breaks the D-String of a guitar. After Apollo starts to play, he and Chiara sob in each other's arms, hitting each other and cursing. When Apollo drops the guitar, he completely destroys it.
While the camp is under attack, he appears with Chiara, Billie, and Paolo setting up ballistae. At the aftermath of the battle, Chiara was a victim to the hay fever outbreak. After Damien learned that Chiara is ill, he got sick as well so that he could have a cot right next to her in the infirmary, and they would be sniping at each other whenever they knew they were being watched.
Damien appears to be sometimes violent. He breaks a guitar's D-String and later smashes it. When Leo, Festus, and Calypso return to camp, he punches Leo (even though he probably doesn't know him) and then gets back into the line.
He is also described to be cunning by Ellis Wakefield in Camp Half-Blood Confidential. However, he displays moments of sheer stupidity such as thinking that the symbol of Demeter during Meg McCaffrey's claiming is the communist symbol.
When Woodrow the satyr was teaching music class, Damien broke the D-String of the guitar that Chiara wanted to use, causing her to become angry at him. When Apollo played the guitar, he and Chiara were sobbing in each other's arms while hitting and cursing at each other. After this, Damien also "reduces the guitar to kindling and wires," causing Chiara to call him an idiot in Italian, for she will never get to use the guitar.
During Harley's Three-Legged Death Race, Chiara was partnered with Damien.
When the plague affected the camp, though, Apollo noticed that right after Chiara became ill, Damien fell ill as well, which Apollo found slightly suspicious.
