06.04.02 - Tuesday: Superstition

Frank tries to piece together a puzzle from his childhood. Kate shows Lucy the latest photo from the barn. Later, the two begin to examine closely the strange parallel lives Alison and Rebecca seem to be sharing. Rebecca explains to Kevin how she's been stuck in limbo for centuries. Following a call to Joe, Frank shakily starts to have flashes of memory about a violent struggle he witnessed when he was small. Certain her husband is with Rebecca, Lucy suggests to a surprised Kate that she may hold the key to bringing Kevin safely home. Meanwhile, Rebecca demonstrates for Kevin how heavenly her private domain can be with a little bit of faith. Frank tells his startled mother he saw her with her lover years ago. Refusing to say die, Kevin informs Rebecca he will find a way to escape their ""paradise"" and return to his wife. Speculating that the only way to save the future is to go back in time and correct the mistakes of the past, Lucy tells Kate she must somehow acquit Rebecca.
