TONIGHT'S MUST-SEE

"Grey's Anatomy," 7 and 8 p.m., ABC. For the second straight Thursday, ABC reruns a pair of pivotal "Anatomy" episodes. Last week was the two-parter that originally followed the Super Bowl. This week, these two hours help get viewers in the mood for the Emmy awards Sunday, with the show nominated for best drama. The first episode begins with Meredith at the bar, waiting to see if Derek will meet her. He won't; soon, bigger problems prevail. A train wreck fills the emergency room with patients. Meredith can't help until her alcohol level goes down; mostly, she watches helplessly. Especially moving is the relationship between two strangers who have been impaled together. The second hour gets back to the soap-opera side. We meet Derek's former friend, whose affair with Addison broke up their marriage.
