It was weird seeing both Abby and Carol from good old ER together - but I think it'll add an interesting dynamis to the storyline, though it did come a bit out of nowhere? Has Maddie ever been mentioned before? Plus the whole possible "romance" between them was a bit of a shocker, I'd never pictured that as a storyline, what with Will and everything.
I agree with Dec1964 - I'm very interested in seeing where Kalinda's story with her husband is going. Why are "English" people deemed interesting on American tv? (I'm English - just interests me that a lot of tv series have a token actor with an English accent). I'm sure that Kalinda could just as easily have been married to an American?
I'll keep watching, that's for sure!
