It was a very emotional episode. I liked how Abby went through her first shift as an Attending and last in County.

Since Carol left the show, she has been the female lead character in the show, no doubt about it.
Weaver was an interesting character as well, but Abby always had more charisma. Her thing with Carter, then Luka. It made the character rich and soon after one of the most important in the series.

The best part was when she went to the board who was going to judge Sam's actions related to another case. That's exactly why I like Abby Lockhart.

And I'm glad they didn't kill her. She had her happy ending.. Bye Abby and Luka. Be happy :D
