I have to agree with kwargalla on this point. Bailey is an awesome character that the writers have brought out more this season than in the others.
As for Mer and Der and Rose I am glad that is over. Mer did have a good point at the end though with the fact that she could not trust Der and that is why she would not totally commit to him.
As for the rest of the cast I can see then starting to develop a bit more patient skills with Christina. IT was soo nice to see her give up a chance to do surgery to hold the babies hand.
As for Izzy and Geroge I can see then starting to develop more of a relationship based on love rather than sex.
