Showtime appear to be unveiling an endless supply of teasing promo videos lately, so why stop now!? Another 2-minute promo to help push the anticipated seventh season of their hit serial killer show 'Dexter' has arrived. The new sneak peek, which is arguably a tad spoilerish (so turn away now), picks up instantly after last season's mouth-opening finale. Dexter attempts to sweet talk his way out of the situation but Deborah isn't exactly going to let this one slide under the carpet. The usual cast suspects are joined by season 7 newbies Ray Stevenson, Jason Gedrick, Matt Gerald, Yvonne Strahovski ('Chuck'), Katia Winter and Calista Flockhart. Check out the new promo below, and make sure you tune in to Showtime on the 30th September when the new season of 'Dexter' kicks off.
