Justin:
Made some quick modifications and markups on the .pdf.
Pink--Typo. Fix it. Or a tense issue.
Green-- Great addition--helps bring out a previously under-developed plot.
Blue--Try reading through without this line--a tentative 'cut' mark.
Improvements! The story really profits from the changes you've made to the structure--from introducing FrancisFordMustang's name on the first page (sets up that he will be pivotal) to the newly added scene with Denny/Russell's abbreviated face-to-face conflict. This helps create a sense of urgency for Russell--you imply that his adrenaline is going and this influences his decision to go and see FFM--or it is slightly more of a factor in his decision making.
You also did some serious work in fleshing out the mother character--she's written as an optimist against all evidence, contrasting nicely with Russell's father's extreme version of utilitarianism, to the point of joylessness. These extremes, coupled with the shiny moral paragon that is Denny, gives more incentive for Russell to leave in a hurry.
Even better--there's a line here that sums up how bleak Russell views his home life:
When Denny is the only one who will first notice your absence, it's not hard for the reader to conclude that perhaps young Russell doesn't feel valued. Good work, man.
See my line notes for more--great second draft, man!
