In this week’s ‘Fringe,’ the team investigates rips in time. Is Peter’s return to blame for these fringe events?

Three shows in, Nick’s heritage comes into question, the mythology of the series is plugging along nicely, and we get our danders tapped about what might be coming down the line. These are the very things making ‘Grimm’ a kick to watch right now.

Michael Westen does a very bad thing. Chuck Finley wants you to save a nest of baby penguins. And Ben Watkins gets to do what many writers wish we could do. Typical ‘Burn Notice.’
