I may be thick but I have question about the ending.
I take it that Edgar dies from his gun shot wound and Julia ends up with Walter and her child. Thus in some way rights the wrong of Julia and Edgar killing Walters wife and child.
I'm pretty good with understanding complex storylines (which this wasn't, it just had a ton of twists) but what I didn't understand was what Walters involvement was in the whole thing. Why was he helping Edgar kill Maicon?
He went to the college only to tell Walter about the final plan. Walter even made a speech about life and death to his students because of the plan and Edgar being there.
