Relationships
Horatio Caine (David Caruso):
Kyle Harmon met his father when he was sixteen. He is distrustful of him at first, thinking that Caine will abandon him "just like all the others." However, as his mother's condition deteriorates, Harmon seems to grow closer to his father, especially after his father gets him a job as the ME's assistant. By the seventh season, Harmon seems to gravitate more towards Caine, as evidenced by his confessions of the problems with his mother to him. During the eighth season, Caine and Harmon seem to have a close relationship, and Harmon shows great trust in Caine. When Harmon leaves for Afghanistan the second time, Caine tells him that he loves him. It is only the third time that Caine expresses the sentiment on the show, the first time being to the body of his younger brother during "Ray." The second was to his wife Marisol in the season 4 episode Rampage.
Julia Eberly - Winston (Elizabeth Berkley):
Harmon is very happy to see his mother when she first appears in "Raising Caine," as he has been looking for her for some time. When Julia and Horatio file separate custody suits for him, he ultimately chooses his mother. For a while Harmon is quite protective of his mother. However, as time goes on and Winston's mental condition worsens, Harmon appears to grow somewhat weary of Winston's unpredictable temperament. The breaking point comes after she goes on a rampage in the second-last episode of season 7 ("Dissolved") and demands Harmon at gunpoint to return with her. He is obviously disappointed as he watches his father have her arrested and later sent to rehab. During the eighth season, Winston is not mentioned by Harmon or Caine, and it is implied that Harmon no longer has much of a relationship, if any at all, with his mother.
