Nashville 10 p.m., Channel 5

No, sorry, the Wednesday episode is yet another repeat. Nice way to lose momentum, ABC. It’s too bad the networks are so locked into the 22-or-so episode season from September to May; it leaves a lot of gaps along the way. Just when “Nashville” seems to be building up steam, it disappears for a few weeks. In this repeat, Juliette (Hayden Panettiere, above) throws a surprise party for Deacon. I don’t quite understand why show creator Callie Khouri brought in Gunnar’s brother, by the way, then killed him off so quickly — before he could fall in love with Scarlett. Subplotus interruptus.
