Isabel Coates

Isabel Coates is Blair Waldorf's loyal sidekick. She remains Blair's friend despite her losing rank as Queen Bee. She was best friends with Kati Farkas and tends to match outfits with her. During the first season, she and Kati often appeared in Blair's Audrey Hepburn dreamscapes and at one point she and Kati also appear in Dan Humphrey's dreams. She is also an accomplished concert pianist. Isabel and Penelope Shafai contribute to the new rift between Blair and Serena van der Woodsen when the position of Queen shifts from Blair to Serena. The see through dress that she intended to wear to the Snowflake Ball is used to humiliate Vanessa Abrams. Isabel, Penelope and Hazel Williams are all present when they plan on declaring Emma Boardman as the new Queen, which went to Jenny Humphrey. Both Isabel and Penelope refuse to have a girl from Brooklyn carry out their legacy but Blair convinces them otherwise.
