In Criminal Minds Season 10 Episode 6 a young woman is killing men who show interest in her.

It takes a while for the BAU to figure out that she's living out a fantasy in which she meets the perfect man. She sees herself as a Cinderella - but continually gets disappointed with the men she meets, who most assuredly are anything but Prince Charmings.

So what do you do when the man of your dreams turns out to be just another frog? Do you let them go or do you teach them a lesson? You can probably guess how that goes.

Meanwhile, JJ has a confrontation with her mother Sandy about keeping secrets from her son. JJ and her husband Will have agreed not to tell Henry about her dead sister Rosaline. Unfortunately, when going through old pictures, Henry saw one of Rosaline and began asking questions. While Sandy didn't say much, other than she's in another place, it did raise more questions with Henry.

You can see how the case works out, and how JJ resolves her differences with her mother when you tune in and watch NCIS online.
