What the Hell Happened on that "Nashville" Series Finale -- We NEED to Talk About Juliette!

While most of the other storylines on "Nashville" came to an end on last night's series finale, fans of the show were left with one MAJOR cliffhanger in the show's final moment ... and man, was it a doozy.

All episode long, Juliette Barnes (Hayden Panettiere) had been making penance for playing a role in Jeff Fordham's (Oliver Hudson) death. While it had previously been assumed by the general public on the show that he killed himself, in reality, Juliette was about to commit suicide in a booze-induced rage, when he intervened and fell off a building.

After Layla Grant (Aubrey Peeples) leaked that intel to the press, Juliette was forced to come clean -- explaining everything that happened in an emotional ABC interview ahead of the Oscars. When her ex and baby daddy, Avery (Jonathan Jackson), found out his new GF, Layla, was involved in leaking the story to tabloids, he immediately dumped her ... and it seemed like a reconciliation between him and Juliette was on the horizon.

She ditched the Academy Awards and hopped on a private plane back to Nashville, to be with her man and daughter. But, in the very last scene of the show, someone came out to the tarmac and told Avery his ex-wife's plane had gone missing.

... and bam, that's how the show ended!

It was a baffling move, as the series could have ended with almost every storyline tied up without that final moment. With ABC knowing that the show wouldn't return on its network, that scene could have simply been cut, and fans would have the happy ending they so deserved.

Instead, we all sit in limbo, waiting to see if anyone else picks up the series for another season. If they don't, we'll never know Juliette's fate.

According to Deadline, the actors actually filmed an alternate, happy ending, in the case the show wasn't picked up ... but instead, Lionsgate TV wanted to end of on a cliffhanger, to make it more attractive to other networks or streaming services to continue the show's run.

With Hayden entering rehab again for postpartum depression earlier this month, don't expect to hear anything from her defending the finale anytime soon. Jackson tweeted a couple times during last night's episode, but didn't say a word about the divisive ending.

His last tweet about the show:

As for Lionsgate TV, they seem confident someone will pick it up:

• Rayna's family drama with both Deacon and Maddie finally came to an end. After Maddie shared an Instagram photo of herself working with a producer from Rayna's past in NYC, the country superstar wrote guest column for The Huffington Post, explaining how he had tried to force himself on her back in the day. She saw this as the only way to reach out to her estranged daughter, who was texted a link to the post just as the guy was starting to perv out on her. Deacon arrived to the studio just in time to save their daughter from being assaulted and the family reconnected back in Nashville. No word on how Maddie will get out of her record contract, but at least there's no more bad blood between them all.

• Scarlett finally professes her love to Gunnar, who spends the episode entangled with the toxic Autumn before realizing his ex is really "the one." He grabs Scarlett for a passionate kiss during their opening set for Autumn's show. It's a very happy moment ... but one that also means they're fired from the country star's tour. Whoops!

• Will Lexington embraced being an LGBT spokesperson, taking his battle against conservative TV talk show host Cynthia Davis to her front door. Though she initially refused to have him on her show, she relented when he and Luke Wheeler set up a pop-up concert protest in front of her studio. He belittled her bigotry on live TV, then stepped outside and reconnected with his newly-single ex, Kevin. Their storyline ended with a sweet kiss.

• Luke Wheeler suddenly realized his ex-wife was actually the woman for him, even though we barely heard about her during the entire show. After helping Will take on his haters, is last seen calling his daughter, asking her to get his ex on the phone.

• Layla Grant gets dumped by Avery after he finds out all the scheming she's been up to all season long. Basically, everyone hates her ... except for America. She's last seen crying in bed, before getting a phone call saying her new album is a total hit.
