Major plot hole (spoilers)
Maybe someone can explain to me, otherwise i can only see it as a huge plot hole... maybe i just got the end of the film completely wrong. But if all 3 of them died in that car crash, simon as well, then what is this whole story with Anna? I assume the car crash took place in 2000... like it was said, and then what happened? we dont actually learn anything about the time between that first car crash and his 2nd accident in 2002... all we know is that anna blackmailed him and married him. Then of course theres the whole fact that in 2002 he was seeing Kate, i think her name is... who also died in the crash... so what the hell was going on? was that just his imagination. I DONT KNOW.
WHY if he knew he was going to push (accidently) his brother off that balcony, why did he go up there and follow him? wouldnt it have been easier to have just let his brother be all pissed with him, then trying to explain things, when you know it will just lead to that accident.
To many things that make no sense.
