This Week's TV: Fringe returns, Katee Sackhoff joins Clone Wars, and 2 shows debut!

In this week's television, Fringe is back — and kicking its universe-spanning storylines into high gear. This week also sees the return of a few of our other favorite shows. Plus the premiere of two brand new shows (to Americans, anyway), including a brand new look at a classic Marvel character.

Meanwhile, Fringe's Kirk Acevedo is trying to save the world from a collision with Mercury. Robot Chicken celebrates its 100th episode in style. Portlandia deals with the perils of Battlestar Galactica addiction. The Simpsons does a Social Network parody. And watch a totally beautiful clip from the next Clone Wars — featuring Katee Sackhoff as a female Mandalorian!

Although Caroline (Candice Accola) is in no mood to celebrate her 18th birthday, Elena (Nina Dobrev), Bonnie (Kat Graham) and Matt (Zach Roerig) surprise her with a small party in an unusual location. Damon (Ian Somerhalder) and Stefan (Paul Wesley) disagree on the best way to handle Klaus (Joseph Morgan), and a reckless Stefan decides to test his theory by taking things to dangerous extremes. Bonnie is concerned when Elena tells her about Jeremy's (Steven R. McQueen) new plans. At a Founder's meeting, Alaric once again runs into Dr. Fell (guest star Torrey Devitto), who is in the middle of an argument with her ex-boyfriend, the medical examiner (guest star David Colin Smith).

In an effort to be a better father, Ethan (Adam Harrington) offers to chaperone the dance, much to Adam's dismay.
