Coming Up on Fringe: More William Bell, More Astrid

A couple Fringe scoops to tide viewers over until tonight's new episode:

• Leonard Nimoy will resurface as William Bell on the season’s 10th episode.
• Astrid will actually leave the lab soon. We'll let producer Jeff Pinkner explain how that will work:

“Astrid gets out of the lab a lot more this season,” he told Entertainment Weekly. “And we just wrote a Astrid/Walter arc.”

Fellow producer J.H. Wyman added that Fringe is "looking actively for ways to expand the character.”

Got any suggestions for the show?
