I didn't realize they stopped playing the theme song. I haven't watched it in several years, though. Maybe I did realize it back then and don't remember.
I know when Weaver was on years ago, they never discussed her leg handicap and the writers were all praised for focusing on her, the doctor, not her physical impairment, as it didn't really effect her doctoring. I notice tonight that she was walking without her brace. Did they ever acknowledge that when she came back? Or was it "just one of those things" and since it never needed reference before, they didn't reference it this time?
