This week on a new "Nashville," season 4 of the country music drama continued with an episode titled, "When There's A Fire In Your Heart." Scarlett and Gunnar, portrayed by actors Clare Bowen and Sam Palladio, find themselves in an awkward position when Autumn Chase, actress Alicia Witt, isn't all that she adds up to be. Maddie, portrayed by Lennon Stella, grows up a lot this episode and so does Juliette Barnes, portrayed by Hayden Panettiere.

The Exes discuss their relationship with Autumn Chase

With Scarlett and Gunnar so close to reuniting, will this be the event that pushes them back together or will it be something that drives them further apart?

Ever since Jeff died Layla has been lost, with music being her only guiding light. She has a new album coming out, and it's promising material, but Rayna is struggling to find her a slot on a major tour as an opening act.

Meanwhile, Layla still has her eyes on Avery, but it's hard to say if it's simply for revenge on Juliette for being involved with Jeff's death or if she's really interested in Avery.
