It was a good episode but...I didn't really understand exactly what was going on until about 20 minutes into it. I usually can decipher who the killer may be by the first 40 min. and then watch to see if I'm right, but I was lost.
I was also confused on the ending. First of all, if the girl was only 16, then shouldn't she've be in foster care since there was no other family? And second, what was the deal with the freaky devil man? Did he seduce her into Hell or something?
I did enjoy the story line though, and I loved how all of my favorite little agents (except Prentiss) were as clueless as I felt. They had the profile way off until my Reid figured it all out. ;D
All in all a fairly good episode.
