Hostage crisis on Ste. Marina.In the Navy, the term "eight bells and all's well" refers to the completion of a watch with no incidents to report. But all is far from well on "Last Resort," as Captain Marcus negotiates a hostage situation while coping with his grief and a possibly mutinous crew.

That storyline is straightforward — the U.S. government has ordered a blockade of the island. Ste. Marina "mayor" and drug-runner Julian Serrat has a shipment coming in, and he's kidnapped three Colorado crewfolk, whom he won't free until Marcus agrees to retrieve Julian's loot. Marcus has until sunrise. Nobody's happy about, as Prosser grumbles, playing "bagman to a drug lord," but the mission goes forward, with some excitement when the Perseus cloaking system overloads the sub's circuits, making the Colorado visible to destroyers on the surface. (The sequence in which an anonymous seamen comes down a ladder and drops his flashlight on the metal floor, tipping the destroyers to the Colorado on sonar, is well done.)

Marysol at home in Miami.Marysol Patton isn't your stereotypical housewife -- she runs the Patton Group, one of the premiere PR firms in Miami — and yet, she's a Housewife. Patton is one of a handful of "Real Housewives of Miami" cast members, along with Adriana De Moura Sidi and Lea Black, who continued on the show for a second season -- and it's a decision she could have regretted. The first season spotlighted, among other things, Patton's relationship with Philippe Pautesta-Herder, whom she married in a romantic snowy outdoor ceremony.

As the second season got underway, though, Patton revealed that she'd separated from her husband. Going through relationship negotiations on-camera, integrating new Housewives like Karent Sierra and Ana Quincoces, and still trying to get some work done could have turned into a nightmare — even with Patton's mother, Mama Elsa, standing by with second-sight wisdom.

But when Yahoo! TV spoke to Patton last week, she seemed upbeat about all the changes. For more about Patton's

Hayden Panettiere as Juliette BarnesRayna James is "the reigning queen of country" — for now. But next big thing Juliette Barnes has her eye on Rayna's throne (and a couple of other things that belong to Rayna), and in the series premiere of "Nashville," it looks like she's going to get it.

"Nashville" is a rhinestone variation on "All About Eve": a fading star who's quietly at war with an insufficiently deferential ingénue, and with the handlers who insist she accept a new reality. Moving the story from the Great White Way to the Grand Ol' Opry makes it even more compelling.

When we meet Rayna (Connie Britton, beloved from "Friday Night Lights" and still rocking some of the prettiest hair in primetime), everything's changing for her. Her newest record isn't charting well and her tour isn't selling out venues, so her record label asks — insists, really — that she "co-headline" with, i.e., open for, new superstar Juliette (Hayden Panettiere, "Heroes"). The demotion's bad enough; Juliette's personality makes it worse.

Robert Patrick understands why he often gets typecast as the bad guy. After all, the 53-year-old actor shot to worldwide fame by tangling with Arnold Schwarzenegger as the liquid-metal killing machine T-1000 in "Terminator 2." And with dozens of film and TV roles to his credit (including stints on "The X-Files" and "The Sopranos"), Patrick is now co-starring on ABC's new submarine thriller "Last Resort" as iron-willed Chief of Boat Joseph Prosser, who clashes with Andre Braugher's Captain Marcus Chaplin when the captain defies orders and goes rogue. But don't be too quick to label Prosser the bad guy.

"Early on, people have coined me as the villain," Patrick told us on the "Last Resort" set. "And you know, that's just baggage because I played one of the greatest villains of all time. It kind of follows you around. Obviously, that's not how I see this guy. I don't think he's a villain. What the f--- did he do?" Patrick went on to tell us (in colorful language) about his personal history

"Arrow" (The CW)Two weapons you can always count on in fairy tales and post-apocalyptic worlds: the slingshot and the bow and arrow.

The slingshot, though, hasn't been sexy since David took down Goliath. The bow, on the other hand, has made a ballyhooed cultural comeback, brandished by the likes of Princess Merida in "Brave," Katniss Everdeen in "The Hunger Games," Hawkeye in "The Avengers," and real-life heroes from the Summer Olympics. And no less than three television shows come this fall slinging arrows, among them "Arrow" (The CW), which debuts Oct. 10, as well as "Revolution" and the returning "Grimm" (both on NBC).

A darker, sexier Arrow

The CW's latest offering in its superhero lineup stars Stephen Amell as Green Arrow, whose pulp antecedents go as far back as Batman in the DC Comic universe. His TV debut, though, drops the "Green" from the title because "Arrow" felt "sexier, a little more dangerous," explains writer and co-executive producer Andrew Kreisberg. "We didn't want people to come

Another viral video success story (kind of)! The talented, adorable and innovative singing sisters Lennon, 13, and Maisy Stella, 6 (awesome names, by the way), known for their cover of Robyn's "Call Your Girlfriend," are guest-starring in this season's most anticipated new show, ABC's "Nashville."

The Stella sisters will be playing Maddie and Maisy James, the daughters of country music falling star Rayna James (Connie Britton). The girls will be performing in a school talent show on what is scheduled to be the third episode.

Lennon and Maisy were cast after the pilot was shot and way before the sisters even went viral on YouTube, so they're technically not a YouTube discovery. But the  "Nashville" casting directors certainly had a sharp ear for raw talent. Harmonizing perfectly while playing empty butter tubs as a unique percussion accompaniment (only kids can find music in everyday things so easily!), the Stellas' Robyn cover video has so far received over 8.5 million views.

Ramona Singer is not having itEvery "Real Housewives" cast is, to an extent, a very tiny and very sparkly high school. Nothing showcases that comparison better than the reunions, which often go on for two or three episodes themselves and force the hardest-working host in show business, Andy Cohen, to preside over fractious, wealthy homerooms all around the country.

Last night's "Real Housewives of New York" reunion featured the usual incomprehensible yelling, "I'm sorry you feel that way" non-apologies, and Cohen shooting the camera "I…can't even" looks. But it hid a few nuggets of gold amid all the finger-pointing. In case you missed the show, here's 7 bits of info you can discuss in the breakroom:

On basic cable at 10 PM, you can say a word that starts with "c" and rhymes with "jock."

WHM and Victoria face offVictoria is officially alive — and Conrad is shocked! Unless he isn't. Or maybe he is. And Amanda really is carrying Jack's baby — but she thinks she isn't, except she really is. Probably? "Revenge" may have lost the plot in "Resurrection," literally.

Last night's episode had so many switchbacks and double-crosses that you may have lost track of who's where, so let's start with the seemingly minor plots. Declan's classmate, Trey, wants him to hold a bracelet Trey (probably) stole from his stepmom, in exchange for $500. Meanwhile, over at NolCorp, a young accounting analyst at the company, Padma, insists Nolan choose a CFO. Nolan likes Padma's moxie, and chooses her, and the whole thing takes far too long.

Numbers games

And the audience could have used Nolan's help with some audience-surrogate narration, because the Grayson scheming got crazy complicated. Emily sucks up to Daniel by tattling on Dr. T, which drives a wedge between Daniel and Conrad, but comes too late to save Charlotte's
