Anyone else disappointed by the ending? (Uncharted 2)

I see that and raise you:

Nate (as Chloe climbs ladder): "It's a shame you have to sit on something so pretty".

--
Chloe (while hugging Nate): "Is that an ancient Tibetan ritual dagger in your pocket?"

--
Nate (while in swimming pool): :"Marco"
Chloe: "Really?"
Nate: "Come on"
Chloe (reluctantly): "Polo"
*Nate jumps out of pool*
Nate: "Fish out of water!"

Don't get me wrong, I loved the sexual innuendo between the two - but that's really where it began and ended for me.
Nate's relationsip with Elena was much deeper, especially having played the first game.

Also, that second example has nothing to do with Chloe, but with an awesome, awesome quirk by the developers .
