Question: David Greenwalt is off Moonlight. Rob Thomas is off Miss/Guided. Surrender the poop, Scoop.
Answer: Greenwalt's Moonlight exit was medically induced (i.e., exhaustion). Thomas, meanwhile, left Miss/Guided for creative reasons, and I hear he's thisclose to lining up a new gig. Here's hoping it includes the words "Veronica," "Mars" and "movie."
