You're Brody after the end of the movie...
You're back on dry land.
Movie Ellen hasn't cheated on you.
What do you do about your future?
Me personally I'd wanna get my family out of dodge city as quickly as a transfer would allow me.
I understand that the shark attacks weren't the norm, but I'd also never want anyone i loved to get in the water ever again, because of experiences and what I'd witnessed.
As I said in another thread, even after Bruce was dead, I know I'd still be absolutely terrified and I wouldn't feel safe until I'd gotten out of the water.
I suppose a big counter argument for my stance would be that Brody had already moved his family once for safety reasons and he couldn't "run away" every time.....
I don't think I'd call that running away. As I believe I'd be traumatised by the whole thing, from seeing what happened to Quint, to the boat virtually sinking around you, to being a lucky shot away from being Bruce's dessert course.
I wouldn't want to stay somewhere that could trigger flashbacks at any given moment.
Edit. The question really is "what do you do, if you're Brody?"
