It was good to learn a little bit about Morgan's background. Her resentment towards her father for not fighting for her is clear, but well, it was nice to see that there is a little heart in Ecklie's tough personality.
I always complain about the writers making the new member so smart and bright. In this case, Morgan makes a huge mistake and she pays the consequences. She did a good job trying to make the criminal believe she was on his side (and at some point she really was), too bad she didn't have enough support and the whole thing failed.
I loved Greg's worriness for her. Knowing immediately what the others couldn't see and demanding the suspect for answers. Very passionate. I'm sure he and Morgan will make a great couple, when it comes to partners of course.
Morgan breaking in the end was very emotional. She just couldn't help it. God, she's only human. Nice scene.
