The story of Sherlock Holmes has been adapted countless times, but he’s has never had a sidekick quite like Dr. Joan Watson, played by Lucy Liu, on CBS’s Elementary. When the show returns on Oct. 30 for its third season, relations between the detective (Johnny Lee Miller) and his sober coach-turned-apprentice Watson are a little strained since she moved out of the house and he took off and joined MI6. TIME caught up with Liu to talk about what’s in store this season — as well as her famous Destiny’s Child shout-out. TIME: You’re in the middle of shooting the third season.
