"Dexter exec Sara Colleton has promised that the next season will be &amp;quot;a game-changer&amp;quot;. It was recently confirmed that the Showtime drama&amp;#039;s latest run will pick up where season six left off, with Deb (Jennifer Carpenter) having discovered Dexter (Michael C Hall) committing a murder. Colleton told TV Guide that season seven will indeed see Deb discover the entire truth about her adopted brother, adding that the discovery &amp;quot;rocks her world&amp;quot;. &amp;quot;If the series-long quest for Dexter was to finally have someone who really knows him... well, be careful what you wish for because Deb now knows everything and that&amp;#039;s a game-changer,&amp;quot; she said. Colleton explained that the theme for the new episodes is &amp;quot;regret, responsibility, shame, betrayal, all of those things&amp;quot;.   &amp;quot;It&amp;#039;s the flip side of wanting to be known, and then once you are known, there&amp;#039;s a loss of freedom,&amp;quot; she hinted. &amp;quot;It comes with heavy responsibility, so [Dexter is] dealing with a lot of emotions that he&amp;#039;s never had before, and never been allowed to feel before or allowed himself to feel before.&amp;quot; The impact of Deb&amp;#039;s discovery on her new-found romantic feelings for Dexter will also &amp;quot;be explored&amp;quot;. &amp;quot;One doesn&amp;#039;t come to a realization like that and then completely change, but obviously what she learns is going to affect it,&amp;quot; Colleton said. &amp;quot;All of the things that have been the bedrock of Deb&amp;#039;s life get moved around.&amp;quot; Dexter returns to Showtime on Sunday, September 30 at 9/8c. In the UK, Dexter airs on FX. &amp;gt; Dexter casts Katia Winter in seventh season Watch a trailer for the new season of Dexter below:      "^^<http://www.w3.org/2001/XMLSchema#string>
