Like one of ABC's other popular shows, Lost, there are a lot of mysteries yet to be solved on FlashForward. There is still plenty of time to explore some of these, but it looks like one of the smaller mysteries will be cleared up this Thursday night when the person who sent Olivia (Sonya Walger) the text message about Mark's (Joseph Fiennes) drinking is identified.
Meanwhile, Demetri's (John Cho) life is at risk. When things look bleak, the FBI talks with terror suspect Alda Herzog (Rachel Roberts). She's willing to tell them where Demetri is, but it's going to cost them dearly.
You can catch FlashForward's "The Garden of Forking Paths" this Thursday, April 22nd at 8:00pm ET on ABC.
