I am writing a story about homeless children in new york city and I need to introduce a really important character but I'm having a lot of writers block. All the kids are hanging out in there hideout with the main character who they are letting stay with them. This character is there "leader" or the person in charge because he is the oldest. I don't really know the best way to bring him in to the story....should he just walk in lol? I know this is a really confusing question but the pointis any good ways to introduce a character to a story???
