I thought Kasha was wonderful in this episode. I didn't really care for her character and it's sad that it took her final episode to see what a really great actress she is. I was quite moved by her performance.
As for the rest of the show, I wish it was cancelled at the end of this season. What is the point of dragging out fourteen more episodes over two years? This show started going downhill for me after Lily was killed. It seemed the new showrunners, writers, producers or whoever have done nothing but alienate the original viewers. The original premise of building the railroad has been all but forgotten. The theme of the week now seems to be who can we kill that can cause the most pain to Cullen. Really?? Someone needs to put him and this show out of its' misery now.
