Twisted twins and doppelgangers. Some engage in incest, others just have horrible, even life-threatening relationships.
For some reason, the shows with twins played by the same actor or actress, in this case Alexandra Chando of The Lying Game, or Sarah Michelle Gellar of Ringer, don't seem to last very long.
But these relationships are always so juicy and dark because even compared to siblings, there's just a certain bond between twins that is undeniable and leads to much deeper rifts in their family fabric.
Seems like daytime soaps have an uncanny habit of revealing a shocking doppelganger.
Below, here are some of our favorite dark, deep, twisty, and puzzling twin relationships.
Elena Gilbert and Katherine Pierce - The Vampire Diaries
Well, they weren't really twins, but doppelgangers are close enough, right? Dobrev did a marvelous job of separating these two, and an eventual third, Amara, but working as two different emotional characters took its toll and Katherine eventually was sent off to hell. Not without torturing Elena one last time though, her favorite pasttime.
Cersei and Jaime Lannister - Game of Thrones
Do we really need an explanation of this twisted twincest relationship? Cersei and Jaime, twins, have three children together due to their abnormally close bond that has led them to carry on a sexual relationship for oh-so-many years.
Emma Becker and Sutton Mercer - The Lying Game
Thankfully, The Lying Game TV show didn't follow the same path and have Sutton Mercer, dead, watching over her sister's search for her murderer. Alexandra Chando effortlessly identified the two girls, not just by their hair, and portrayed such a torn relationship between two girls that never stood a chance. Emma wanted a family, Sutton took hers for granted, that's how it always would be, and that's how it was when the show was cancelled.
Jessica DiLaurentis and Mary Drake - Pretty Little Liars
While we're still getting to know Mary Drake, Andrea Parker has done magnificently well masking the fact that she plays both of these secret-ridden, devious mothers. Which is the evil twin? Are they both evil? All we know is that their relationship was less than ideal.
Jack Abbott and Fake Jack - The Young and the Restless
Ever thought about the fact that you're supposed to have an exact doppelganger walking around somewhere on Earth? Well, Jack Abbott discovered his in the most unusual way - sleeping with his wife! In another attempt to take him down, Victor found Fake Jack (real name, Marco Anniselli) in a Peruvian prison, stiffed him up, and brought this shiny fake home to stir up trouble, while Jack was kidnapped and switched out on his wedding night. Ugh.
Jesus and Mariana Adams-Foster - The Fosters
Ignoring the recasting of Jake T. Austin's Jesus, these two twins had a lucky life. When their mother was unfit to care for them, they hadn't been separated, but instead were placed in a loving, safe home with Stef and Lena. But, as with any teenagers, they bicker like siblings, fight dirty, and they love each other more than anything, no matter what's thrown at them.
