Sam Grey

Season 1
Ep01: Pilot

Sam Grey is first seen attending his father, Thomas Grey's funeral. There, he meets his psychiatrist, Karen Kim. When he shows up at Karen's office, he tells her that he knows that his father had a mistress from a note he found from her. He explained that he needed to find the woman because he wants to know if his father was truly alone when he died or if she was with him so he could know what his last moments were like. He asks Karen if she was his mistress and she said no, even though she was.
