Daria
This was very different from most episodes of Daria. It wasn't really a wry look at reality, or illuminating a problem with the typical twist. It was a straight out study of the events that shaped Jake and Helen's daughter into the girl she is today. There was a lot about her sister Daria, also.
Quinn taking the box back to the curb the second time was the first time I can remember with Quinn in a prolonged moment by herself and not putting on her front for possible observers. Mouth like a longshoreman on that girl (assuming that the cartoon euphemism equals the comic book euphemism).
The scene in the car, when they're coming back from the psychologist. 'look at me!, please, look at me!, I'm being everything you wanted out of Daria, please notice me!' Daria hasn't really thought through how much her bahavior growing up, and the concomitant focus by her parents on her, shaped Quinn.
And, of course, the box and the note at the end.
