Charles Esten, Christina Chang

Nashville fans knew it was only a matter of time before the tension between Teddy (Eric Close) and Deacon (Charles Esten) came to a head this season — but judging from a sneak peek of Wednesday's episode, exclusive to TVGuide.com, a confrontation may be imminent.

Fall TV Scorecard: What's renewed? What's canceled?

In the clip below, Megan (Christina Chang) tells Teddy that their recent tryst was a mistake, but doesn't realize that Deacon's within earshot. Whoops! What is it with Teddy swooping in on Deacon's sloppy seconds — first Rayna (Connie Britton), now Megan? And given all the clashes the two men have had over Maddie (Lennon Stella) this season, it appears that this may be the final straw for Deacon.
