'Nashville' 'Don't Open That Door' Sneak Peek: What If Rayna Can't Ever Sing Again? (VIDEO)

"Nashville" has been a roller coaster ride of emotions week after week, but this week's episode, titled "Don't Open That Door," might just be the most dramatic yet.

We've got an exclusive sneak peek at the next episode of "Nashville" (Wed., Oct. 23 at 10 p.m. ET on ABC), an episode that looks pretty close to entering "very special episode" territory. As country music living legend Rayna James (Connie Britton) wonders if she'll ever be able to sing ever again, her on-again, off-again lover/partner/baby daddy Deacon (Charles Esten) isn't thrilled that she's been keeping this from him.

Might we see Deacon help rehabilitate Rayna the way she's helped him through his issues so many times before? (And can we say for the record: These two are made for each other.)

Watch our sneak peek, above, and tell us: Do you think Rayna and Deacon could ever live happily ever after?

"Nashville" airs Wednesdays at 10 p.m. ET on ABC.

Here's ABC's official description of “Don’t Open That Door”:
In advance of a benefit concert starring all of Edgehill’s best acts, label head Jeff Fordham (Oliver Hudson) demands that his new artists sell themselves as hot, sexy personas—which is a major struggle for Scarlett, and Layla knows it. Since Rayna is unsure about her future as a singer, she plots to buy out Edgehill’s rights to her music, and Gunnar and Avery decide to record new songs with Zoey, Scarlett’s best friend. However, by the end of the concert night, nothing will be the same.
