Kat ND

 Katherine "Kat" Corrigan Has the gift of the Sight, but lately, after Derek's return, has been having... instinctive knowledge more along the lines of a Seer, like Christina (a Seer that had visited her as a young child and had protected her when the Cantwells tried to come back to life and kill Kat and her mother, Rachel)

She spends part of her time in California, and has a room at Derek's home, and goes to stay with her mother during holidays when Rachel is working in New York.
