I am so glad they didn't leave Amita's fate last week as the season finale until fall. I loved the return of Ian Edgerton as the team scrambles to find Amita and the cult that took her. One of the aspects of this episode that I actually really liked was Charlie initially taking a step back and Larry stepping forward in the math department. I thought Amita communicating with Charlie through charges on his credit card was pretty creative. I loved seeing the team come together in efforts to save their colleague as well as recognizing somewhere along the line, she became a friend. Seeing Don's amazing insight as to how Mason thinks and utilizing his 'flock" to get to him was great. Charlie getting down on one knee was perfect.
