10 Spoilers: An 'Arrow' game-changer, a 'Supernatural' angel dilemma, plus 'Bunheads' goes all the way

nina-dobrev-jared-padalecki-sutton-foster.jpgSince Mondays are just the worst, we here at Zap2it have decided to give your week a much-needed wake-up call with 10 TV teasers -- just to remind you that when the work day is over, your DVR waits to welcome you home.

This week, our Monday Kickstart includes some scoop from our latest "Vampire Diaries" set visit, dish on a major "Bunheads" rite of passage, and some thoughts from Jared Padalecki on whether the "Supernatural" guys would ever betray Castiel to get rid of all the angels. Plus -- don't miss this week's "Arrow." Seriously.

"The Vampire Diaries": We visited the set last week and -- in addition to getting some scoop on Tyler's return -- we also got to watch Nina Dobrev pull double-duty as she filmed a scene for episode 418, "American Gothic." In the past, we've seen Katherine pretend to be Elena plenty of times, but now, we'll get to see Elena's best impression of Katherine. Katherine didn't seem too impressed by the likeness, though... she thinks Elena's innocence will be a dead giveaway. (Not to mention her haircut.)

"Arrow": Stephen Amell has been referring to this episode with the term "Holy s***balls," on Twitter, and after getting a sneak-peak viewing of it, we can confirm that he wasn't being hyperbolic. The episode is really that crazy. This week's "Dead to Rights" features a pivotal moment that will change Oliver's life -- as himself, and as the Arrow -- forever. We'll also hear Laurel reference a canary for the very first time.

"Bunheads": In tonight's winter finale, Sasha demands that Boo, Ginny and Melanie all participate in a group research project. The subject? Sex. The goal? To keep their boyfriends interested. But only one of the girls actually goes all the way with her guy, and you'll have to wait until the end of the episode to find out who loses her virginity.

"Psych": Shawn has always been known for going his own way when solving a case, but when his father is put in danger in the Season 7 premiere, he goes even further off the book than we've come to expect of him. After all, it is his dad we're talking about. Oddly enough, he has an unlikely source encouraging his rogue excursion into crime fighting.

"Supernatural": Right now, the Winchesters' No. 1 priority is closing the gates of hell to keep all the demons out. What they don't know yet, though, is that in addition to the demon tablet, there's an angel tablet, which could lock all the angels away for good. The question is, would they be willing to banish Castiel in order to rid the world of all the other angels? "I absolutely think the boys would sacrifice Castiel to get rid of the angels," Jared Padalecki tells us. "I think they are, not one-track minded, but goal-oriented enough to where you've seen them sacrifice themselves or others to try and accomplish a bigger objective ... I feel like they would do it. I could be wrong, but I feel like they would do it."

"Archer": Anthony Bourdain guest-voices "Bastard Chef" Lance Casteau at ritzy restaurant "Seize" (pronounced "Says"). The ISIS agents are there undercover to protect the Albanian ambassador -- complete with Archer as Sous Chef Randy Randerson -- but Chef Casteau may turn out to be the real person everybody needs protecting from.

"The Following": How anxiety-inducing was last week's cliffhanger episode? Things are only about to get more harrowing. The longer that Claire goes without seeing her son, the more she begins to unravel. "She just hits her breaking point," Natalie Zea tells us. "There comes a point where she realizes that crazy people do the same thing over and over again, expecting a different response. There comes a point where she's like, I could either be crazy, or I could change." In fact, expect a pretty big confrontation between Claire and Ryan in an upcoming episode. "I definitely bruised Kevin Bacon," Zea teased. "I don't know my own strength."

"Hart of Dixie": Despite being let down big-time by Wade, Zoe isn't going to give up on finding love. In fact, when she goes on a date with a much older guy -- thanks to a little nudge from Rose -- she begins to think that someone more mature might be just what she's looking for. Of course, because this is Zoe Hart, somehow her venture into responsible-adult-dating lands her at the high school prom.

"The Americans"
: Lots of things can destroy a carefully planned spy operation. Misplaced loyalties, infiltration and even dumb luck are expected. But what happens when an asset's emotions are compromised. In "Comint," the KGB stands to lose all missile-defense information because one man can't move past the death of his beloved wife. And the spies can't offer needed emotional support with the FBI watching. (Also, if you want to get valuable and classified information out of the FBI, buy your source a pair of fancy pumps.)

"Southland": In an upcoming episode, Ben and Sammy get invited to a retirement party for Maureen... a toothless prostitute known as the "tooth fairy." Classy -- but hey, it's an open bar. Surprisingly enough, though, the event isn't all fun and games. Ben learns a little something about Sammy's past at the party.
