A part of Hal's curse was also to bring in demigods to be eaten by three leucrotae who feed at sunset.Luke was angered that the gods would do this to Hal and wanted to find a way to rescue him and Thalia.They were running out of time and ways of defeating the leucrotae until Luke discovered they could make Greek Fire, after hours of searching the Internet with no solution.Within the hour, they had created the Greek Fire from different ingredients and some lightning. The 24-year-old actor, who plays Ian in the upcoming book-to-big screen adaption, chatted with EW about his role.
“Ian’s one of the last remaining humans, part of the human resistance that’s trying to survive this alien invasion,” he explained about his character.
One morning, they had reached Richmond, Virginia, where once again, Thalia was in pursuit of Amaltheia.
Luke seemed to have a crush on Thalia and just couldn't tell her no, even though he knew it was against his better judgement.
Luke didn't know what he meant, but was disturbed from what he said.
Hal also gave Luke his personal diary and a dagger and made Luke promise that he would learn from his mistakes and not be pushed around by the gods.
Hal told them that every demigod thought that at first, that they could escape, but soon realized it wasn't possible.
