Network executives must like the direction that the series is going in the upcoming Sixth season. It’s been about six month since Season 6 was announced.
Season 7 is a long way off so we can’t really speculate at this point where it might be headed. Hell, we don’t even really know what to expect from Season 6 yet! It’s not supposed to even air until summer of 2019. It will also only consist of 13 episodes. I imagine Season 7 will have the same amount of episodes.
I’m not a huge fan of this show but there are aspects of it that I enjoy and I’m curious to see how the story for these characters end up playing out.
