Rayna (Connie Britton) and Deacon's (Charles Esten) relationship will take center stage in the upcoming episode of the hit ABC series "Nashville."

In "Can't Get Used to Losing You," Cartermatt reports that trouble is brewing between the lovebirds as Rayna becomes worried about her fiancĂ©'s latest business venture. Apparently, Deacon is in communication once again with a friend from AA. Frankie (Mark Collie) is managing a bar and Deacon wants a portion of it. He wants to forge a partnership and rename the place after his sister. Rayna is concerned that being in close proximity to alcohol will tempt her man to go back to his old habits. Deacon is a recovering alcoholic, which makes managing a bar potentially problematic. Will they be able to overcome this hurdle together?

Meanwhile, Luke (Will Chase) is facing some tough times ahead with his son Colt (Keean Johnson). When Juliette (Hayden Panettiere) attempted to jump off the roof last episode, her manager Jeff (Oliver Hudson) accidentally fell instead. Colt saw the whole thing, and he could tell if the country star would be lying about the incident. When Luke told her someone saw her on the roof with Jeff before he died, Juliette denied the accusation, saying she was alone in her room that night.

Will Luke try to convince Colt to forget what he saw? If he does, their personal relationship may indeed be in danger of taking a hit. His son has proven that he has a stubborn streak. Last week, he stole a bottle of alcohol from Luke's party. The superstar is more likely grounding the kid because of it. If he still insists on shielding Juliette at his son's expense, there is no telling what kind of misbehavior Colt will exhibit.

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