Well in the twin theory one of them WAS alive so I don't see what the problem would be for a twin to exist. That's pretty much the main storyline and drive of the entire PLL book series. And the show no matter how much they try to make it less similar is still based on the books. It's not a minor love side storyline or a red herring that they can just toss aside.
