Answer:
Luke helped Percy settle in the camp as a new arrival. He stole "a sleeping bag" and "some toiletries" for him to use to get settled, and walked him through the camp, be it dinner-time, the burning of food to the gods before one eats them.
Explanation:
Rick Riordan's "The Lightning Thief" revolves around the story of demi-god Percy Jackson and his 'journey' to know his father and live life as a half-human, half-god. The Greek mythological story is a part of the series "Percy Jackson and the Olympians".
In chapter 7 of "The Lightning Thief", Percy has just arrived at Camp Half-Blood, a secure camp for demi-gods like Percy. This camp helps the young children of the gods and also keep them safe and teach them how to live life as a 'demi-god'. Luke is the son of Hermes, and in this chapter, he helped Percy get settled in the new camp. He 'stole' a "sleeping bag [. . .] and some toiletries" for Percy and helped him get through the dinner ritual of "burn[ing] offerings to the gods" before they can eat their food. He also answered some questions about whatever Percy asked him, as much as he can.
