Because the flight windows are so far apart, I interpreted it to mean that Vincent, once there, was set. They couldn't really send him back even if they wanted to. And I read Jeromes suicide as the last act to "cover up" for Vincent (and Jeromes name). What would people say when someone found Jemore, alive or his corpse, in the home on Earth? The last step was to disappear completely. If I recall correctly we were sh…
Why would they need to send him back? Just imprison him in Titan. Also, society is based on genetics - where you work, where you live, who you date, etc. How did Vincent expect to live on Titan without Jerome's samples? I think the answer is he never intended to live on Titan because he knew he'd die on the way to Titan. We know that his heart can't handle the journey ( treadmill scene ).
> What would people say when someone found Jemore, alive or his corpse, in the home on Earth?
The same thing the cop said after questioning the wheelchair bound Jerome. Apologize after Jerome berated him and demanded his badge number. Besides, given your point about the flight window, what would it matter? Why would Jerome need to cover for him when Vincent's set on Titan?
I think that Jerome always intended to kill himself from the very beginning ( we know he's suicidal because he's in a wheelchair because of a failed suicide attempt ). Not to "cover up" for whoever he was helping, but because "Jerome wasn't meant to be 2nd place". In the incinerator, "2nd place Jerome" and his silver medal are no more. I also don't think he help vincent for the money or for vincent's sake though they developed a friendship towards the end. We know he was bitter at society ( and himself ) and I think he wanted to screw society once before offing himself.
In the end, it's two people dying to escape their "identity". One trying to erase his "invalid" identity and the other trying to erase his "2nd place" identity. And both perishing in the process.
