Considering that the show only intended to last through its first five years, 'Supernatural' fans often don't know what they're in for when a season begins.  The same can be said for 'Supernatural' season 8, which marks the first effort under former writer Jeremy Carver, and a possible setup for the eventual end of the series.   So what is Carver saying about the last, and upcoming season of 'Supernatural' that has people curious?

New 'Supernatural' show-runner Jeremy Carver has plenty on his plate when it comes to picking up where Sera Gamble left the series, Dean trapped in Purgatory with Castiel while Sam once more attempts to carry on with a normal life.  Still, with the impressive mythology set up over seven seasons, Carver hopes to re-imagine things more simply to add new viewers, he tells TVLine.

The one thing that struck me [while] watching Season 7 was I felt like the show got a little bit buried under its mythology. It became a little hard to tell exactly what was going on at times. The longtime fans all deserve intricate plot, but it felt a little burdensome....Resetting our mythology was one idea that I tried to bring into [the show]

But if the show manages to make things more accessible by showing the Winchester brothers reunite, what does that mean for the bro-mance that is Sam and Dean?  “Part of this season is realizing they didn’t just spend several years together; they really matured in different ways,” explains Carver. “It’s one thing to get in a car with your brother in year one, but eight years later, you’ve both matured and grown. You’re both changing and trying to find out who you are. There’s a lot of that type of exploration for these guys this year.”

To date, we've learned that 'Supernatural' season 8 will see the return of DJ Qualls' eccentric  hunter Garth, as well as "Futurama' voice Lauren Tom.  Elsewhere, ‘Battlestar Galactica’ veteran Ty Olsson will appear in an important recurring role, that of a vampire named “Benny,” whom Dean meets during his stay in purgatory and ultimately helps him escape from said predicament.  Liane Balaban (‘Alphas,’ ‘Covert Affairs’) will appear as Sam’s new love interest Amelia, developed in the time the brothers spent separated, but ended by the season premiere.
