So I was sad on the movie on how it portrays memories as fixed events. We know that memories have lots of holes we can just fill with imagination and that memories can be induced. I got early that he being pushed by the police was the source of his memory killing her. In the situation he was, drugged and whatnot, it'd be impossible for him to extract any reliable info.

He was a very bad subject for the experiment. And police should just examine his and her hands to find who shot.

But then, after all the mess Anthony did, he just decides to cooperate and sacrifice his life to save Tom? And then Tom just remembers a memory that Anthony himself didn't have of her suiciding?

This was a very messed and badly written ending.
