Okay, since the show is cancelled, part of me thinks this is what someone wanted all along. (There is soap opera and then there are total cl*sterf*cks where none of the characters are redeemable. Man alive.) How will they wrap this up? S/G will be together but continue like Rayna and Deacon, the early years, without the drinking. Will will finally get to perform and get several grammy's. (That man needs a summer party song to launch his career. No more of the ambiguous relationship songs. Give him something happy and fun.). Layla will continue to have a modicum of success but will end up hosting a song writers night at the Holiday Inn. Avery will recognize that Layla is just a little crazy, but she will still call him to check the monitors at her songwriters night. And he will be successful as a producer. Juliette and Avery will get back together of course and they will have two more kids. And Juliette will be a better mother than she ever thought she could be.
Teddy will get out of prison and take Daphne because Rayna is off the rails. In some ways an ex-con looks like a better parenting choice than Rayna and her self centered/Maddie centered life. Maddie will hit the skids and will run into the Homeless Musician Girl. And at this point, Maddie will be over 21 so she can bar back at Layla's songwriters night. And of course, Rayna and Deacon will weather thru all of this drama. Because of love, soul mate, blah, blah, blah.
All in fun.
