You might think Fringe has the strangest love triangle of all time — after all, it just gets more unusual the more we learn about it. But actually, science fiction and fantasy have given us plenty of other freaky love triangles — here are 10 other contenders.

10) Beta by Rachel Cohn
In this new young-adult science fiction novel, coming out in 2012, a teenaged girl and her clone are both in love with the same guy. And they're stuck in a bioengineered tropical paradise. The inevitable movie version will no doubt be lovely to look at.

9) Barnabas, Angelique and Josette — Dark Shadows
The vampire, the witch and the dead woman. Barnabas is torn between the innocent Josette and the Creole witch Angelique — and when he chooses Josette once and for all, Angelique curses Barnabas to be a vampire forever. He's left questing to regain his humanity and find a way to be reunited with Josette, who's now dead.

8) Emma, Jean and Scott — The X-Men.
Scott was still married to Jean Grey when he started having psychic adultery with Emma Frost — who frequently dressed up in a Phoenix outfit in their telepathic interludes.

7) Dead Ringers
In this typically weird David Cronenberg movie, Jeremy Irons plays twin gynecologists, who specialize in creating horrific implements to use on mutant women. And they're both having an affair with the same mutant woman — who doesn't realize they're two different people at first.

Nite Owl, Silk Spectre II and Dr. Manhattan — Watchmen.
Dr. Manhattan's love for Laurie saves the universe. And Nite Owl's love for Laurie sets him back on the path of being a superhero. And of course we get the bizarre image of multiple versions of Dr. Manhattan making love to Laurie.

5) Damon, Stefan and Elena — The Vampire Diaries.
They're both vampires — which is probably no weirder than a werewolf and a vampire being in love with the same woman in Twilight. But add to that the fact that Elena's the identical duplicate of Katherine, the vampire woman they were both in love with back in the nineteenth century, and she's part of a long line of "Petrova doppelgangers," and it gets considerably odder.

4) Wanda, Melanie and Jared — The Host by Stephenie Meyer.
Wanda is a mind-controlling parasite that's taken over Melanie's body, and Jared is the man Melanie loves. But after spending some time in Melanie's body, Wanda has the hots for Jared too — and now he has to choose between his girlfriend, and the creature that (kinda sorta) controls her mind.

3) Mellie, Paul and Echo — Dollhouse.
Poor FBI agent Paul Ballard — he just wanted to be a knight in shining armor, but his damsels were never the people he thought they were. For a long stretch of this show's run, Paul was torn between Mellie — who was a personality constructed by the Dollhouse to spy on him — and Echo, who was also a "doll" but at least had a real personality. Sort of.

2) Troi, Riker and Riker — Star Trek: The Next Generation.
Just when Deanna Troi thinks she and Will Riker are just friends, she meets his duplicate, created by a transporter accident. The second Will Riker still has a thing for Deanna, and won't take no for an answer — which probably leads to the "original" Riker rekindling his interest. But honestly, we still think Deanna should have ended up with Worf.

1) Saul Tigh, Ellen Tigh and Caprica Six — Battlestar Galactica
Okay, where should we begin? Saul discovers he's a Cylon and starts having sex with Caprica Six — but he sort of hallucinates that she's Ellen, whom he thinks he murdered. And then Ellen comes back from the dead, and for a while Saul is torn between the two Cylon women. (Until Caprica Six has a miscarriage, and then he never even notices she exists after that.) Add to that the fact that Saul is sort of Caprica Six's dad, and it gets extra creepy points. Plus consider all the other love triangles on the show, including Athena-Boomer-Helo. Basically, if you were on Battlestar Galactica you were apparently either a Cylon or you were in a weird love triangle with one. Sometimes you were in a love triangle with the same model of Cylon.
