All eyes will be on 'Dexter' season 7 this coming September 30, given how the show's sixth season finale "This is the Way the World Ends" blew the lid of the show's established rules.  We already caught a bit of the fallout in a special two-minute sneak peek back at Comic-Con 2012, but does the shocking reveal go even further than what we've seen?  What clues in the latest behind-the-scenes featurette suggest that Dexter and Deb will have an even more complicated relationship than we thought this year?

If you're here, we'll assume you know and drop the spoilers pretense.  So now that 'Dexter' season 7 will open on the immediate consequences of Deb finally learning her brother's big secret, how will the dynamic between the adopted siblings change?  And perhaps more importantly, exactly how much of the truth will Dexter tell his sister, given that she now heads the very Miami Metro that could put him away for life?

According to the latest juicy behind-the-scenes sneak peek of 'Dexter' season 7, it may not be all that long before Deb finds herself fully up to speed on her brother's murderous lifestyle!  Not only do we know she discovered him plunging a knife into Travis Marshall, but shots from the four-minute preview below suggest that she find's Dexter's full array of tools and keepsakes as well!  Will any explanation of Dex's be able to sidestep that, as in years past?

Of course, both Dexter and Deb will have plenty more on their plates this year, as season 7 will see the arrival of  of ‘Chuck‘ star Yvonne Strahovski as “Hannah McKay,” a woman with a dangerous past who finds herself embroiled with Miami Metro.  The new episodes will also introduce ‘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.”
