The first time Thalia is described in TSOM, her eyes are "sea green" (Percy's dream). When Percy actually meets her, they are "stormy blue". And then the rest of the books she has electric blue. Several other mistakes are how Silena Bureaugard's appearence keeps changing from being blonde to black-haired, having brown or blue eyes. In TSOM, Blackjack is a mare. Chris Rodriguez is mentioned to be unclaimed, therefore in the Hermes cabin. In The Ultimate Guide, he is listed as a son of Hermes.
