Again, very emotional storyline and Abby - oh, she really made this work. The way she has ability to see trough people and understand if there is a change to help them and she has the passion - it was beautiful.
But it was not only Abby. Neela is doing also very well and she likes working in science and saves a life of his fellow scientists. And somehow, it looks, she is still good ER doctor and she could be very valuable help for them.
So, in overall, concentrating on Abby and Neela and showing how those two are doing.. and Abby in the end, taking a boards again.. Hope she will pass them this time.
