# Sid — The Adventures of Tom Sawyer character guide > Sid in The Adventures of Tom Sawyer by Mark Twain. **Role:** supporting **Also known as:** Sidney, Siddy **First appearance:** 0001-the-adventures-of-tom-sawyer ## Snapshot Tom's smug half-brother, whose quiet tattling gets Tom whipped and whose reward is a hail of clods the moment Aunt Polly turns her back. ## Who they are Sid is the obedient, well-behaved counterweight to Tom in Aunt Polly's household, and he knows exactly how to profit from his brother's failures. He calls attention to Tom's black thread and lands him in trouble, then takes the punishment for it in a volley of dirt clods that Tom launches before fleeing over the fence. He matters because he keeps Tom's home life a low-grade war, sharpening the itch to escape that drives Tom toward Jackson's Island and every scheme beyond it. ## Relationships ### [Tom Sawyer](https://www.betterreads.dev/discover/tom_sawyer_se/characters/tom_sawyer) _family_ Sid is Tom's half-brother, a tattletale and model boy who frequently gets Tom into trouble. ### [Aunt Polly](https://www.betterreads.dev/discover/tom_sawyer_se/characters/aunt_polly) _family_ Aunt Polly is Sid's aunt and guardian, often favoring him over Tom due to his obedient nature. ### [Tom Sawyer](https://www.betterreads.dev/discover/tom_sawyer_se/characters/tom_sawyer) _family_ Sid is Tom's half-brother, a tattletale and model boy who frequently gets Tom into trouble. ### [Tom Sawyer](https://www.betterreads.dev/discover/tom_sawyer_se/characters/tom_sawyer) _family_ Sid is Tom's half-brother, a tattletale and model boy who frequently gets Tom into trouble. ### [Aunt Polly](https://www.betterreads.dev/discover/tom_sawyer_se/characters/aunt_polly) _family_ Aunt Polly is Sid's aunt and guardian, often favoring him over Tom due to his obedient nature. ### [Aunt Polly](https://www.betterreads.dev/discover/tom_sawyer_se/characters/aunt_polly) _family_ Aunt Polly is Sid's aunt and guardian, often favoring him over Tom due to his obedient nature. ## In the story ### [The Adventures of Tom Sawyer](https://www.betterreads.dev/discover/tom_sawyer_se/chapters/the-adventures-of-tom-sawyer) Tom's half-brother who is observant and reports Tom's misdeeds to Aunt Polly. ### [Tom Plays, Fights, and Hides](https://www.betterreads.dev/discover/tom_sawyer_se/chapters/i-tom-plays-fights-and-hides) Sid reveals Tom's trick about the sewn collar, prompting Tom to threaten him. ### [The Glorious Whitewasher](https://www.betterreads.dev/discover/tom_sawyer_se/chapters/ii-the-glorious-whitewasher) Sid is mentioned as someone Aunt Polly would not allow to whitewash the fence, reinforcing Tom's claim of the task's exclusivity. ### [Busy at War and Love](https://www.betterreads.dev/discover/tom_sawyer_se/chapters/iii-busy-at-war-and-love) Is pelted with clods by Tom, breaks the sugar bowl, and silently notes Tom's omission of prayers. ### [Showing Off in Sunday School](https://www.betterreads.dev/discover/tom_sawyer_se/chapters/iv-showing-off-in-sunday-school) Already learned his lesson, contrasting with Tom's struggle. ### [The Pinch-Bug and His Prey](https://www.betterreads.dev/discover/tom_sawyer_se/chapters/v-the-pinch-bug-and-his-prey) Sits with Aunt Polly and Tom in church. ### [Tom Meets Becky](https://www.betterreads.dev/discover/tom_sawyer_se/chapters/vi-tom-meets-becky) Tom's half-brother who is fooled by Tom's groaning and fetches Aunt Polly. ### [IX: Tragedy in the Graveyard](https://www.betterreads.dev/discover/tom_sawyer_se/chapters/ix-tragedy-in-the-graveyard) Sid is sent to bed with Tom and falls asleep quickly, unaware of Tom's plans. ### [Dire Prophecy of the Howling Dog](https://www.betterreads.dev/discover/tom_sawyer_se/chapters/x-dire-prophecy-of-the-howling-dog) Awake and aware of Tom's late return, but does not reveal it. ### [Conscience Racks Tom](https://www.betterreads.dev/discover/tom_sawyer_se/chapters/xi-conscience-racks-tom) Sid notices Tom's strange behavior, including his restless sleep and avoidance of inquests.
