What to Watch Sunday: Finales for The Killing, Girls and Four Others, Racy Cupcakes and More

On TV this Sunday: Father’s Day = Finales Day, as many series draw to their seasonal close. What’s better than a tie or some golf clubs? How about The Killing catching a killer and Nurse Jackie celebrating a special birthday, not to mention Girls’ boy trouble and a Borgias betrothal?

Here are 10 shows, in addition to Falling Skies‘ return (linked below), to keep on your radar.

8 pm Cupcake Wars (Food Network) | Bakers compete for the privilege of cupcake-catering a VIP party for this year’s Los Angeles Marathon – because only people who’ve run 26.2 miles can afford to indulge in a 500-calorie sugarbomb.

PREVIEW | Falling Skies Season 2: Expository ETs! Tom’s Chilly Welcome Home! And a Ray of Hope?

9 pm The Killing (AMC) | In part two of the Season 2 finale, Sarah and Holder close the case, Richmond’s got a new thing going and the Larsens finally get closure — but not from where you’d expect.

9 pm Drop Dead Diva (Lifetime) | While Jane thinks her client is holding out on her, Kim and Parker become Owen’s sister’s divorce lawyers and Grayson helps Stacy and Nikki get one step closer to bringing pake (pie + cake) to the masses. (God bless them.)  TV vet Patty Duke guest-stars, while Valerie Harper returns as Judge Singer.

9 pm True Blood (HBO) | Bill and Eric go to New Orleans to meet Salome and get some firsthand knowledge about the Authority’s interrogation techniques – that’s also where we first meet SVU alum Christopher Meloni’s Roman. Elsewhere, Tara shows up in Bon Temps and Alcide doesn’t want to be the werewolves’ new packmaster.

9 pm 2012 MuchMusic Video Awards (Fuse) | LMFAO hosts the pop music awards show, which features appearances by Glee’s Darren Criss and Chord Overstreet, Dallas’ Jesse Metcalfe, Pretty Little Liars’ Lucy Hale, 90210’s Shenae Grimes and Modern Family’s Rico Rodriguez.

9 pm Nurse Jackie (Showtime) | Season finale: Dr. Cruz pushes Jackie to the breaking point, and O’Hara’s baby decides it’s time to be born.

9:30 pm The Big C (Showtime) | From the network: “Cathy finds herself spending time with a stranger.” That doesn’t sound very eventful, but this is the Season 3 ender, so there’s probably more in store, no?

10 pm The Client List (Lifetime) | Season finale: It may be Father’s Day, but Kyle’s return is anything but welcome. Meanwhile, Riley finds herself running The Rub of Sugar Land. Betty White, Law & Order’s Elisabeth Rohm, Heroes’ Greg Grunberg and One Life to Live’s Trevor St. John guest-star.

10 pm Girls (HBO) | In the buzzy series’ Season 1 finale, Hannah questions her relationship with Adam (that’s funny, I’ve been questioning it from the get-go), Jessa throws a mystery party, Marnie loosens up and Shoshanna’s quirks turn into assets.

10 pm The Borgias (Showtime) | Season finale: Lucrezia’s finally remarrying! Yay! But Cesare’s confession nearly does the Pope in, and then Antonello steps up to finish the job. Boo!
