JMO is IMO the one they have to get cause she’s the star of the show
Unless S7 is a complete different thing altogether. Like how Charmed introduced Billy and intended her to be the star of the show from then on. For all we know by the end of season 6, we could have a whole new cast of characters, following them on a whole new adventure, with only occasional appearences by the ones we originally saw. But I don’t think that is the case UNLESS they are doing a flashforward where we see Henry all grown up going on adventures with grown up Baby Snowflake and grownup Gideon. I think that could be a show. I’d probably watch.
We know how well that works out for the show…see Scrubs S9.
But A&E don’t care about that, they don’t care about what makes sense for the story or the characters. If they can continue the show even without Jennifer, they will. They get more money by doing season 7 instead of just ending it with 6. Moreover, reealistically, and I hope that A&E realize that, that season 7 will probably be the final season with or without Jennifer, so ratings or fans or shippers don’t factor into decision about how to handle the show. In the end, A&E will do what is most beneficial for A&E.
JMO indicated that she has no interest in abandoning the character and I fully believe she will do S7 for sure. And yes absolutely ratings cannot justify anything more than S7 and TBH a short S7 of 13 episodes.
