I love the references in this episode!
Chloe to Clark: "Well, put a cloak on me and call me Horatio."
Not to mention the fact that Jonathan's "Ghost" telling Clark to kill Lionel parallels the Ghost of Hamlet's father telling Hamlet to kill Claudius. Lionel was inadvertently responsible for Jonathan's death and he did try to form a relationship with Martha.
