BEST: "Castle" — Someone shot Kate, and Castle finally professed his love for her. Yeah, talk about your cliffhangers. Last we saw, she was seemingly dying on the ground with Castle hanging over her. And that was after she had come face to face with one of the men who had killed her mother. And we were still reeling from the earlier revelation that the Chief, who had always seemed on the straight and narrow, was actually involved with the guys who murdered her mom. It was shocking and definitely left us eager for next season.
