Renly’s death occurred in the fifth episode of season two of GOT just moments after he’d negotiated with Robb’s mother Caitlyn (Michelle Fairley) the terms of their agreement.
However, during their negotiations, the youngest Baratheon sibling committed a rather obvious blunder.
As pointed out by one eagle-eyed fan on online forum moviemistakes, they explain: “When Renly and Catelyn are negotiating the terms of Renly’s alliance with Robb, Renly calls Moat Cailin ‘Moat Caitlin.’
“As someone who served as Master of Laws on King Robert’s Small Council, he should know the correct name of the territory he is referring to.”
