"Elementary" Season 3 release date / air date will be October 30, here is what we know about the new season of the show.

Joan will have a new boyfriend, Andrew, but one of her exes will come back into her life in the seventh episode, according to a new report from TVLine. "Camargo's character, Chris, is Joan's former medical colleague as well as her ex-boyfriend. He reaches out to her for help with a problem - but during the course of their association, old feelings get stirred up. (Rumor has it the two were thisclose to getting married back in the day.)"

According to a new report from TVLine, there is going to be "at least 20″ episodes in the upcoming season, and the number may end up ballooning to a little more than that depending on what happens in the schedule.

There is a new trailer showing Joan (Lucy Liu) and Kitty (Ophelia Lovibond) getting off on the wrong foot in Season 3 of "Elementary," the two nearly come to blows. You can watch the trailer below.

Lucy Liu's character will face a nemesis while still coming to terms with Sherlock Holmes' new protégé, Kitty Winter.

According to Fashion & Style, Joan Watson (Lucy Liu) will not be getting along with Sherlock Holmes' (Jonny Lee Miller) new protégé, Kitty Winter, (Ophelia Lovibond). The two are seen in a preview "preparing for a battle of the batons," the article noted.

Ace Showbiz clarifies that Watson and Winter's first meeting happens before the new character is introduced as Holmes' new protégé. It remains unclear what Winter's motivations are, but it has allegedly been revealed by CBS that her "reasons for undertaking Holmes' partnership are nebulous."

 Fashion & Style reports Phil Simms will be appearing on season 3 as himself. The article says Simms will be in the November 13 episode as Holmes' old friend. CBS considers Simms a "surprising, little known talent" that will join Meryl Streep's daughter, Mamie Gummer from "The Good Wife," in making an appearance. Gummer will be a New York heiress named Margaret Bray.

While Watson is trying to figure out how to deal with Winter, she will also be facing a new nemesis, a socialite that Watson suspects of running a drug cartel, named Elana March. March will be played by Gina Gershon.

"I was counting on you dying," she says to Joan in what appears to be an otherwise civil lunch date.

According to TV Guide's full character description, Elana is "a socialite whom Joan suspects of running a notorious drug cartel," and "Joan's pursuit of Elana quickly becomes personal, with Elana demonstrating the lengths to which she's willing to go in order to avoid prison."
