This was definitely an amazing episode, and I absolutely loved watching it. The storyline behind it waxs amazing, and I can't wait to see what happens in the next season's premiere.
I quite enjoyed the fact that J.J. is pregnant. Great news for her, and I hope it all goes well for her!
The case was intense, and it was gripping and enthralling for every single minute and second. They did a superb job with ti, and it really was a memorable one.
I would highly recommend this one. It was brilliant and had all the characteristics of a great episode, and a sublime cliffhanger! Keep it up, Criminal Minds, as this is absolutely amazing television!
