Subject: Me and My Shadow - S1.E8

Through her counseling, Chloe meets a boy who is afraid of his own shadow. Literally. He is convinced that there is some evil presence that lurks in his shadow and that it is coming after him. Though she treats this as a psychological problem at first, once Chloe sees some things that even she can't explain away, she brings in Derek and the Freakylinks gang.
