SPOILERS!!!
ending and plot twist were amazing BUT the thing with the Coroner made no sense. After Isaac died, the coroner told them that he'd "seen this before" and then he proceeded to tell them that killing someone else will save them by giving them more time.
1. If this all happened before flight 180, how could he have seen this before
and 2. WHERE did he come up with that idea??
anyway great movie just a plot hole
