Psychiatrists rarely, if ever, request their patients with Dissociative Identity Disorder (formerly known as Multiple Personality Disorder) enter an inpatient program at a psychiatric hospital. An outpatient program is more common. (edit) Crime lord Rupert Thorne makes his first appearance in this episode along with his henchwoman for the two-parter, Candace, and Harvey Dent's fiancée Grace. (edit) Richard Moll, who plays the dual part of Harvey Dent and Two-Face, was somewhat of a Two Face in the voice cast for this entire series. He showed up numerous other times as the voice of the Bat-Computer and other smaller parts. (edit) This episode reveals the origin of Two-Face. (edit)

Rupert Throne: (Reading Harvey's file) Listen to this boys. Says here that when Harvey was a little boy, he was bothered by a bully. Everyday the bully would bug him after school, until one day little Harvey got so mad, he sluged him one.
Thugs: Oooh.
Rupert Throne: Of course, the bully ran away, which made little Harvey very proud. Until he heard that the bully was in the hospital.
Candace: That was some punch.
Rupert Throne: That's what Harvey thought. Except the guy was in the hospital for appendecitis. But poor Havrvey felt so guilty, he never showed his anger again. And that was the start of Big Bad Harv. (edit) Big Bad Harv: There's just one problem...
Thorne: What's that?
Big Bad Harv: You're talking to the wrong Harvey. (edit)

(Dent is leaving his election-night party early, after receiving a call from Rupert Thorne with the threat of blackmail)

Bruce Wayne: You’re in trouble.

Dent: My friend, you don’t know the half of it.
(edit)

Dent Supporter: Oh, Mister Dent, I want you to know that I voted for you two times!

Dent: Well, ma’am, I trust that it was in two separate elections.
(edit)

(Dent has just roughed up a thug who was being brought into police custody)

Gordon: What in the name of heaven did you think you were doing?

Dent: I… don’t know… I guess he just pressed the right button.

(beat)

Gordon: That’s one heckuva button.
(edit)

The part where the thug kicks mud onto Harvey's suit, is the same side that becomes "dirty" or in other words, where he is hidesouly deformed. After that incident Harvey shows his two-face side by attacking the thug. (edit) When Harvey is initially taken to hospital following the accident, you can clearly see his neck (and presumably all lower) is unaffected, as is his hair. When Two-Face emerges, the skin on the left side of his neck is blue, and his hair is half white. In the second part of the episode, it becomes clear that even his left hand has been turned blue. (edit)

In the therapy session, one can see an outline of what will become the scarred left side of Two-Face during a flash of lightning. (edit) The scene where Harvey asks for a mirror resembles the scene from Batman when a surgeon had just finished operating on the Joker and he asks for a mirror upon seeing the doctor's expression of horror.
