Showtime serial killer drama 'Dexter' delivered an elegant and intriguing opening to the final season with last night's "A Beautiful Day," one which Showtime was kind enough to place online for fans, but the fun doesn't stop there. The network has also released two new previews of next Sunday's follow-up, "Every Silver Lining," as well as a new trailer for the season going forward! Hannah McKay's back, y'all!

The first clip from next week's episode sees Deb interacting with her new boss, Jacob Elway ('The Boondock Saints' star Sean Patrick Flannery), a far cry from the treatment Deb used to receive at Miami Metro. Meanwhile, Dexter continues to unravel the mystery of Dr. Evelyn Vogel (Charlotte Rampling), who continues to reveal surprising secrets shared with Dexter, and Dexter alone.

Finally, Showtime's overall trailer from the season hints that Vogel may have a larger part to play yet, while we glimpse the return of Yvonne Strahovski's Hannah McKay! And might Deb finally confess her and her brother's sins to Miami Metro, or are we being led down the wrong path?

We've included both the new trailer and clips from next week's "Every Silver Lining," so check out the latest from 'Dexter''s final season, and give us your predictions in the comments!
