What challenges did percy jackson face in chapter 6 the lightning theif

In this chapter, we learn that Chiron is showing Percy around the camp. However, in this chapter, Percy encounters several challenges. He realizes that everywhere he goes, campers stop and stare at him. Moreover, as Percy arrives to the cabin where he will be staying, he realizes that the cabin is old and run-down, with chipping paint. Moreover, this is the cabin of "undetermined" people. This means that no god has yet claimed to be related to Percy. Finally, Percy is taken by Clarisse to his "initiation," which involves a humiliating dunk of his head in the toilet water, although this never actually takes place as the water pipes explode.
