She attacks him, and tells him to forget what he saw, that this is only a dream. Kali moves over to a picture on Dereks table, a picture of Rachel and Kat, Kali looks at Kat and smiles. (A sinister smile). The next morning at Clairemont School, Kat is beginning school. She gets teased by older girls and runs away.
