It doesn't make sense, because if Kenneth supposedly had sex with the twin while Jessica was pregnant, he would obviously have noticed the difference. And if she went to Radley, then who took care of Cece? Oh and also, by the time Jessica was pregnant with Jason, the affair between her and Peter was already done, so the twin couldn't have "switched" places.

You guys really try to complicate things while the obvious answer is that Ali has a twin, not Jessica, Cece, Kenneth or Jason (yeah I've heard those too). They're going by the books, as they did with Mona and Ali being alive. They only replace some stuff so we won't predict everything that's going on in the show but remember that PLL is based on Sara's novels, so the overall action can't change.
