While last night's all-new 'Dexter' episode "Argentina" felt mostly like a relaxed, contemplative episode, next Sunday's "Helter Skelter" will definitely live up to its name.  Unable to be talked out of his murderous vendetta against Dexter, Isaak (Ray Stevenson) next sets his sights on hurting Hannah McKay (Yvonne Strahovski)!  Will Deb be willing to help her brother out, following last night's tense confession?  Watch the clips inside to find out!

A new day has finally dawned for 'Dexter,' as the series seems ot have found a renewed energy and purpose not seen for years.  Last night's "Argentina" certainly proved that point, weaving together multiple stories from the current and season's past, but with four episodes remaining in the season, is the spatter about to hit the fan?  It certainly looks that way given the below clips from upcoming episode "Helter Skelter."

In the first sneak peek, we see that Isaak has taken it on himself to set up in Dexter's own apartment, threatening to put Hannah's life in jeopardy if not for his help!  In the second clip, Dexter petitions his sister for aid with the situation, but given her hatred for Hannah and confession of feelings for her brother, it isn't likely Deb will jump at the chance to offer her help.

What do you think the final episodes of 'Dexter' season 7 will bring?  Will Hannah McKay survive the season?  What about Deb?  Watch the clips from "Helter Skelter" below, and give us your predictions in the comments!
