999 PointsHow do you know which characterName this.characterName refers to????
I had assumed it would always refer to the characterName we'd just typed in the brackets at 2.06 he says it refers to the characterName in line 2. Does it always refer to the first one declared or something?

Putting a "this." prefix on a name refers to something in the class rather than a local variable of parameter of the method.
