Like blood spurting from an open wound, there's just no end to the awesomeness of the full-length 'Dexter' season 7 trailer! If you thought you'd seen it all before in either the brief teasers or the full scene released  at Comic-Con 2012, think again. The killer's out of the bag for Dexter and Deb, and the full look at season 7 makes it quite clear we're in for a bloodbath.

No more lightning-speed teasers, Showtime has released the full two-minute trailer for 'Dexter' season 7, overflowing with new footage! The seventh season, premiering Sunday September 30 along with the season 2 premiere of 'Homeland,' will deal with the fallout of Debra stumbling upon Dexter's big serial-killing secret in the final moments of season 6 finale "This is the Way the World Ends," as well as a host of new complications for the brother-sister pair.

In addition to the major casting of ‘Chuck‘ star Yvonne Strahovski as “Hannah McKay,” a woman with a dangerous past who finds herself embroiled with Miami Metro, ‘Dexter’ season 7 boasts some impressive talent. We’re referring, of course, to ‘Heroes’ star Santiago Cabrera as an investigative writer and ‘Luck‘ star Jason Gedrick as an owner of a gentleman’s club, which frequently plays host to fellow castmate (and likely major villain) Ray Stevenson, a “high-ranking member of an Eastern European crime ring who arrives in Miami determined to learn who killed one of his associates.”

There's a lot to take in with the full 'Dexter' season 7 below, as we're still pouring over every frame, but it certainly raises some tough questions. Will Dexter have to focus his murderous tendencies on his own sister to keep himself above the law? Will others stumble onto the secret as well? What new threats will emerge to challenge Miami Metro, and who's going to bite the big one?
