Pretty much my point, that that was the closest thing to it, which isn't really anything.
And true about Nick. Those little guys witnessed Splinter murdered even.
If PD wants to ever venture into a third and add some darkness, then, I dunno... do something big, like kill of Fox's April. And Vern maybe. That would be okay. Distraught Casey then can have a break down and snap, becoming a Casey we recognize.
Prob why those films won't go dark though. They'd end up having to be rated R and lose all that kid money.
Yup, HBO or something needs a TMNT project.
