I think my favorite scene was from 'Lane Miserables' where she thinks she's gotten over him and then he makes the comment about how it was too bad she wasn't older. The one where for one brief shining moment she gets her vision of the perfect future, and then she's like... 'Damn'.
But after he had his 'almost growing up' moment in IICY, there's a lingering hope that he may yet become a productive member of society.
