"Vampire Diaries" season 5 spoilers reveal that a new doppelganger is coming to Mystic Falls, and that the highly-anticipated introduction of the first gay character on "The Vampire Diaries," Luke, will coming in episode 16!

"Vampire Diaries" season 5, episode 16 won't air until March 20, after a week's hiatus for the CW series. When it does air, we will get to meet Luke, the first gay character on "TVD."

According to CarterMatt.com, Episode 16's synopsis reads: "When Stefan (Paul Wesley) tries to explain recent events to a very sick Elena (Nina Dobrev), her first instinct is to call Damon (Ian Somerhalder). At the same time, Damon is trying to figure out how to make a disturbing confession to Elena. While going through Dr. Wes' files, Caroline (Candice Accola) discovers a frightening secret, and is surprised when Enzo (guest star Michael Malarkey) appears, claiming to have the solution everyone is searching for. At Enzo's insistence, Caroline asks Stefan to meet her at a mysterious location where they are joined by a group of Travelers, including Sloan (guest star Caitlin McHugh), who reveals new information on the importance of doppelgangers. During spring break on a mostly deserted Whitmore campus, Elena runs into Luke (guest star Chris Brochu), a student who seems to know her, though she has no memory of meeting him. Recently dumped by his boyfriend, Luke proposes that he and Elena spend the break getting drunk together, but she sends him off on an urgent mission to find Bonnie (Kat Graham) and the "newbie" witch, Liv (guest star Penelope Mitchell). Damon finally tells Elena the truth about his recent activities, and they come to a new agreement about their relationship."

Sounds like it's going to be a pretty dramatic episode!

Meanwhile, in episode 17 (which will air March 27), spoilers reveal that another doppelganger will meet the "Vampire Diaries" gang! This leads us to wonder: how many doppelgangers are there? Will the new doppelganger look like Stefan or Elena - in other words, will it be a doppelganger of Silas, Amara, or someone else completely unexpected?

Wetpaint.com reports that the synopsis for season 5, episode 17 ("Rescue Me") reads: "In order to keep Stefan from being harmed by Sloan and the Travelers,Caroline and Enzo agree to make a trip to Atlanta to find a newly discovered doppelganger."
