Quinn knew what was up and Batista just didn't want it to be true. Dexter didn't give a shit if it held up to scrutiny or not, he only needed to bullshit enough to not get arrested right then and there.
That said, the actual execution of the scene sucked. Pretty much how I feel about the whole thing - the ideas weren't terrible, but the writing was ugh. Couldn't they have found a windy day to film the boat scene?
/tinfoilhat or they just wanted an ending that would create an outcry for more Dexter so they can revisit the character a few years down the road with a bigger budget and give fans a real ending, be it a happy ride off into the sunset or accidentally sawing off his own leg with a chainsaw.
The way they left it could almost be a reboot - Dexter back to an emotionless killer, only now he doesn't give a shit about pretending to be normal and he's the first guy on everyone's list when bodies turn up. Dexter as a real monster again, at least for a time. Maybe have him questioning why he even bothers to stick to the code. Until at some point whatever happens and he's hit rock bottom and decides he's punished himself enough. Harry's code protected him but not the people around him and was that really his fault? He should have been locked away not fucking trained to kill people.
You have to laugh though. I mean, his wife gets carved up and its his fault and he hardly gives a shit. But his sister takes a bullet and he turns into a goddamn basket case deadbeat dad?
