As previous spoilers have revealed, Dominic Monaghan is now a series regular on FlashForward. He joins the ABC drama in its third episode, coming on board as the character of Simon.

In the FlashForward clips below, viewers (and Mark Benford) get introduced to Simon, who seems both mysterious and shady from the start.

We also get an in depth look at Olivia's vision of the future. This character is also played by a Lost alum, Sonya Walger. It's a bit disconcerting to see her in bed with someone other than Demond...
