Michael and Lindsay - Arrested Development
Lindsay may have been adopted at the age of three, but for most of her life, she believed that Michael was her fraternal twin so they've earned a spot in this slideshow. Michael places family above everything else works strives to keep them together while Lindsay is rebellious with a jaded personality and a flair for the superficial. Out of all the Bluth's she's closest with Michael.
Nicky and Alex - Full House
When I say Full House twins, everyone automatically assumes I'm referring to Mary-Kate and Ashley Olsen. But while the twins took turns playing the adorable Michelle Tanner, the character herself wasn't a twin ('Michelle Rides Again' doesn't count). However, the show did have twin boys, Uncle Jesse and Aunt Becky's bowl-haired boys, Nicky and Alex. In the Netflix reboot, Fuller House, the dudes make an appearance before embarking to follow their dreams of opening a food truck.
Phoebe and Ursula - Friends
Unlike the zany and creative Phoebe, her twin Ursula, who first appeared on Mad About You, was an evil pornstar. While Phoebe loved everyone, Ursula only loved herself. They couldn't be more different, and that's why they never really had a relationship. It probably didn't help that she dated Joey whom Phoebe considered part of her "real family."
Sarah and Helena - Orphan Black
Sarah and her daughter, Kira, are sought after by the Dyad institute because she and her twin sis, Helena, are the only clones capable of reproducing with Kira being the first offspring of one of the clones. Sarah wants a better life for them, and when she sees Beth's suicide, she steals Beth’s identity, along with her money and boyfriend. But she soon learns Beth was embroiled in a deadly police conspiracy making her the newest target.
Josie and Lizzie - Legacies
Josie and Lizzie are twin daughters of Alaric Saltzman and Josette Laughlin. When Josette was killed by her evil brother Kai, Lizzie and Josie were magically transferred into Caroline Forbes via the Gemini Coven and she became their mother. Josie is very much like her real mother — level-headed, brilliant and caring. Lizzie, on the other hand, is a typical high school mean girl with rage burning inside of her that causes moods swings and powers that are harmful to others. Josie protects her sister and keeps her grounded, but Lizzie abuses that kindness forcing Josie to always be “second best."
Emma and Sutton - The Lying Game
Emma Becker and Sutton Mercer are the modern-day Tia and Tamera. Separated at birth, unaware of each other, and leading completely different lives. Emma grew up in as a foster kid while Sutton was taken in by a wealthy family who allowed her to live out a normal teenage life. All of that changes when they find out about each other. Emma turns to Sutton after an encounter with her family and Emma assumes Sutton’s life while she searches for their birth mother.
