This was a beautiful episode of CriminLal Minds, in terms of Derek and Garcia and at the very end, it was really sweet how she had created an office for him - especially the photograph in the drawer!
Furthermore, regarding the actual case, it was a really creepty one - watching the UnSub hunt was quite spooky, but the suspense factor is definitely worthy of a 10/10. I love how what led them to discover the occupation of the killer, with regards to the damaged eye! That was truly brilliant writing!
I also loved the ending, with Hotch chasing him down! Very well don! So far, it has been really interesting seeking Derek Morgan in charge! I hope he does well, but obviously Hotch should get back there sooner or later! I still don't like Strauss though.
All up, I totally loved this episode! Please keep up Criminal Minds!
