(Inspired by the book)

You are Joffrey’s sibling. He’d always wanted to make his father acknowledge him, to praise him

Robert had a thing for hunting, so an idea came to the boy’s mind. He would go for a hunt himself

So Joffrey went out and caught himself a kitten, and brought it back to the castle

Robert was furious and slapped the poor boy so hard, you thought your father had killed him

Later you visited his chambers to find him sitting on his bed with a unreadable expression
