A couple of weeks ago, Dominic Monaghan first showed up in FlashForward as the mysterious Simon, who announced that he and Lloyd Simcoe were the cause of the blackout. Or so we were led to believe...

This week's episode, titled 'Scary Monsters And Super Creeps', sees Dom in all his glory (literally) and sets in motion a series of events leading to episode seven, mysteriously described by David S. Goyer as "game-changing".

The latest instalment also sees Demetri and co investigate the attack on Janis, leading them to make a discovery which further proves that Mark's vision may well have been the future after all. Hit 'play' below to watch some previews:
