Mmm.  The closest I can think on the spot of is the FvJ commentary; they talk about Jason's loyalty to his mother and, how when he figures out that Freddy's using him, all bets are off becasue you "don't mess with Jason's mama."  There's probably something else, FvJ definitely has the most character depth for Jason.  I don't have the F13 DVDs, I'm afraid, so I can't use them as references.  Having looked at your sandbox though, all the "moral crusader" stuff has also been said of Michael Myers (my personal favourite of the big three).  Would it be OR to draw a brief comparison between the two, provided you didn't explicitly say that Jason was influenced by Michael?
