8 - 20: The Letter

A letter from Dr. Greene arrives via fax, and Carter reads it to the staff. Everybody is stunned when he reaches the last page, a note from Dr. Corday, stating that Mark died that morning. Frank posts the letter and various staff members who weren't in attendance take time to read it. Sandy gets Weaver to admit that she's lost a friend. Luka, Abby, Haleh, Susan and Gallant are joined by Weaver and Sandy at a bar. Carter comes looking for Abby and they end up talking all night at Doc Magoo's. Abby goes to an AA meeting later that day, and tells Carter that she went for him. Carter takes his place as the rock of the ER. Meanwhile, Susan learns that Chloe is in rehab and Suzie is staying with Joe, Pratt matches County, and Romano operates on a girl with a genetic deficiency.
