Piggy's first concern is to learn everyone's name and to have a meeting. He tells Ralph he doesn't care what they call him as long as it is not Piggy. Unfortunately, this is exactly what he becomes known as. He is also worried about his asthma and this is why he won't swim in the lagoon. We begin to see that he is physically weak but mentally strong. Piggy is also concerned that they won't be rescued. They have seen no sign of adults on the island and Piggy recalls the pilot talking about an atomic bomb and that everyone is dead. Ralph, on the other hand, is just taking time to enjoy how pleasant and beautiful the island is. Piggy keeps repeating that they have to do something. He thinks they need to organize; he needs some type of order to feel safe.
He is already establishing himself as a responsible, wise, and thoughtful person. His main concern is getting the boys together and establishing some kind of order. When he and Ralph find the conch, he explains that they can use it to summon the boys to a meeting. And from this point on, the conch becomes a means to create and sustain order on the island. The conch becomes a symbol of order. Piggy believes in what the conch can do.
