What three roles does the dialogue play in this passage? "lloyd, i’m warning you. if you read a single word from my diary, i will tell the whole school about your misadventure in the pool last summer," dana bellowed. she tried unsuccessfully to wrestle out the journal from her brother's strong grip. "no you won't,” said lloyd. “i already gave you half of my allowance to forget that. you promised to never bring it up." "ha! you really thought fifty bucks would buy my silence. give me back my diary or else." dana’s face was turning as red as the color of her curly hair. "now i’m gonna definitely read this diary,” said her brother. “that way, we’ll be even." lloyd tried to hold the journal in one hand, while his other hand struggled to keep dana away. his height gave him an advantage, but dana was quite pretty strong for her size. "knock it off, both of you," roared their older sister, amy, from the hallway. "if you don't, i’ll share the video of you two dancing at uncle gary's wedding last year." dana and lloyd froze with looks of horror. they knew their sister was perfectly capable of carrying out her threat. they decided not to risk it. it resolves a conflict. it develops the theme of friendship. it advances the plot to the story’s rising action. it develops the siblings' personalities. it introduces a conflict.
