Kate Mara

Our top moments of the week:

11. Worst Surprise Party: On Switched at Birth, Kathryn's new BFF Renzo surprises everyone when he turns her impromptu book party into a murder-mystery game. However, the biggest surprise comes later in the evening, when Kathryn overhears her husband, John, talking to their son's mother-in-law, Jennice, about the kiss they shared while Kathryn was out of town. Kathryn reveals herself as the (fictional) murderer, cuts the party short and then kicks John out of the house. That's one way to kill the mood.

10. Best (Non) Reveal: House of Cards star Kate Mara stops by the Late Show with David Letterman to talk about the second season of the hit Netflix drama. However, the actress knows better than to outright spoil viewers about the events of the Season 2 premiere (see below) and only drops a few subtle hints. "I am so happy to be alive and sitting here right now. I'm glad I took a car and not the subway to your show," she says with the smallest hint of a smile. Master manipulator Frank Underwood taught her well.

9. Best Game: It's not quite the Miracle on Ice Part II, but the United States-Russia Olympic group play game is thrilling from beginning to end — emphasis on "end." The game goes to a nail-biting eight-round shootout, with the U.S. prevailing after T.J. Oshie scores four clutch goals out of six tries to secure the win. Looks like he listened to Herb Brooks.

8. Worst Twist: Another big bomb is dropped on Pretty Little Liars when Aria learns that Ezra knew (and hooked up with) Alison before he ever met Aria. But Ezra explains that he was actually writing a true-crime novel about Alison and her subsequent disappearance, and in the final minutes we see a faceless A, with his or her signature gloves, picking up the pieces of the manuscript Aria threw in the woods. So if Ezra is not A, who is?

7. Best Change of Pace: Though they seemed like early frontrunners heading into the live shows of American Idol, contestants Spencer Lloyd and Marrialle Sellars don't even get enough viewer votes necessary to land among the Top 13 on Thursday's results show. Heartthrob Spencer is chosen as one of the five who get to sing for the judges' wild cards, but Marrialle is unceremoniously sent home. And Spencer's run also comes to an end minutes after Marrialle, as he gets passed over for one of the wild cards. Critics who say the show preordains its winners officially don't have a leg to stand on this season.

6. Best Explanation: After weeks of going back and forth, The Bachelor's Sharleen decides to leave. After her one-on-one date with Juan Pablo, she goes to his room to explain her decision. But she sums it up perfectly in her accompanying talking-head interview: "I wish I was a little dumber," she tells the camera. So does ABC! 

5. Best Tribute: Amy Adams breaks down into tears on Inside the Actors Studio, which was taped days after Philip Seymour Hoffman's death, when talk turns to Doubt, the first of two films she made with the late actor. "I wish you all could get a chance to work with him," she tells the audience of film students after a lengthy pause. "He's a beautiful spirit. He had this unique ability to see people, to really see them — not look through them — he just really saw people. And he will be missed. I just really loved him and I know so many people did. And I just don't know how much I can talk about it right now." "You've said everything that needs to be said," James Lipton replies.

4. Best Welcome Wagon: On his first night as host of The Tonight Show, Jimmy Fallon explains that he made a bet with a friend not so long ago. "To my buddy who said that I'd never be the host of The Tonight Show, and you know who you are, you owe me 100 bucks, buddy," he explains. At first, Fallon's comments seem like a legitimate shout-out to an old pal -- that is, until Robert De Niro emerges from the curtain and slams a $100 bill on Jimmy's desk. But we're not done yet. He's followed by a cavalcade of bold-faced names, including Tina Fey, Joe Namath, Rudy Giuliani, Mariah Carey, Tracy Morgan, Joan Rivers, Kim Kardashian, Seth Rogen, Lindsay Lohan, Sarah Jessica Parker, Mike Tyson and Lady Gaga, who each pay off the bet. Last but not least is Stephen Colbert, who pours a bucket of pennies all over Fallon and his desk. "Welcome to 11:30, b----," Colbert yells, right after he takes a smiley selfie with a seemingly annoyed Fallon. Your move, Jimmy!

3. Most Convenient Death: On Downton Abbey, Lady Mary finally learns that it was Gillingham's valet Green who raped her lady's maid Anna. Not satisfied to let the matter drop, Mary decides to tell Gillingham -- without a full explanation why -- to fire Green. He agrees, but before he can can him, we learn that Green has suddenly died under suspicious circumstances, stumbling in front of a bus in Piccadilly. Hmm, it just so happens that Anna's husband Bates had the day off that day... Moral of the story: If you come between Anna and Bates, it's not going to be so easy being Green.

2. Worst Interview: Bode Miller's interview after tying for the bronze in the Olympic super G takes a turn for the awkward when Christin Cooper presses him about his brother Chilly, a snowboarder who died last year from a seizure. "When you're looking up in the sky at the start, we see you there, and it just looks like you're talking to somebody. What's going on there?" she asks. Miller doesn't answer, but instead leans down on the fence and sobs. Was Cooper out of line? Maybe. (Miller defends her.) But NBC did choose to air it unedited hours after it happened.

1. Best Kill: House of Cards doesn't waste any time reminding viewers just how ruthless Frank Underwood can be. After pretending to agree to a fresh start with the dogged reporter Zoe Barnes, Frank pushes her into a freaking oncoming subway train in the Season 2 premiere. Like Zoe, we did not see that coming.
