Tonight's must-see: "House"

A pain-free House opens his third season on the run. Literally. After eight weeks of rehab from the shooting, he's running to the hospital, where two patients await him. One is a mute quadriplegic (the result of brain cancer) who drove his wheelchair into a pool. The other is a paralyzed young woman who injured herself in a yoga accident. But there's no evidence of spinal damage. House wants both cases because, he says, he wants to help the patients.

Debut: Ron Livingston and Rosemarie DeWitt star as ace FBI crisis negotiators Matt Flannery and Emily Lehman. They're also clandestine lovers---until Matt outs them as a couple as a negotiating ploy with a hostage taker in the opener. It works since the crisis ends peacefully, but it also strains their relationship. Plus, their boss (Gina Torres) wants to break them up. But before that can happen, a young man in Islamic garb with bombs strapped to his chest takes over an L.A. coffee shop.

A follow-up to the 2003 episode "Time for School," which followed first-graders in places around the world where free and compulsory education is not available to all children. Included are interviews with education professionals from various countries.

Cheryl and Jim join other parents to preview a sex-education video for Ruby's class. But it has one big flaw: child actor Jim.
