Here's a look at tonight's sci-fi TV:
Fringe, 'Peter' – It's been a tough few months for Fringe fans. Sure, there was much rejoicing when Fox announced the third season renewal in March, but the show has been on break since early February, leaving us teetering on the brink after the cliffhanger ending of the mid-season finale, "Jacksonville." Now it's time for more rejoicing, because the wait for new eps is finally over. Fringe returns tonight with Walter coming clean to Olivia about Peter's possibly otherworldly origins. Walter's story takes us back to the 1980s to introduce Peter's mother (Orla Brady) and illustrate how our favorite flatulent scientist took his first steps into the parallel universe. (9 p.m. ET on Fox)
FlashForward, 'Better Angels' – Characters are on the hunt for answers tonight on FlashForward. Vogel searches for clues to the Blackout in Somalia, Olivia tries to coax Charlie to reveal what she saw in her possibly world-changing vision, and Bryce tells Nicole about his cancer. (8 p.m. ET on ABC)
Also new tonight:
- The Vampire Diaries (8 p.m. ET on The CW)
- Supernatural (9 p.m. ET on The CW)
