The unsub was completely crazy and I must admit it kinda freaked me out that some people could have no quarms about doing what he did. The laugh he did was nightmare worthy and kuddos to the actor as he did a great job.
The main elements of this was the interractions between the team members and it made you feel so sorry for Spencer and then to say he went to JJ for help and she never said anything breaks your heart for him. Hopefully they will work it out and like Morgan said, he cant be mad because Emily is there.
The end ing was brilliant and so light hearted it made up for the freakiness of their work. Another great episode from CM, its looking like it will shape up to be another great season.
