Showrunner Wendy Mericle: We made a choice at the top of this season not to … not to get them back together right away, for sure. And to leave that question up in the air. Which I think is a really real thing to happen. [..] In season four, we saw them work together while trying to maintain a relationship. Now, they’re working together in the context of not knowing what their future is, romantically.
I think both sides provide — having them together and apart — certain types of storytelling opportunities. This season has certainly given us different ones. But I think ultimate the key thing, and i think is true for so many series, especially ones where you’ve been fortunate enough to go to 100 episodes and beyond, that you have that central core relationship and as writers you have that opportunity to explore it. And you can take it many different directions. We definitely have some ideas about where we’re headed in Season 6. We’ll see where that goes.
