How come Bond went back to the ship in FYEO?
Basically after Bond and Melina go underwater to get the ATAC, they are attacked for the ATAC, not just by one guy, but a second guy in a sub as well. After defeating both of Kristatos's men, Bond and Melina, decide to go back to their ship that they came on, before going underwater to find the ATAC.
But why do they do this? Surely they must suspect that Kristatos and his men have taken over the ship, and have spotted it, before going underwater. So why would Bond and Melina go back to the ship, when it's likely been seized?
Also, the movie tries to reveal that the men are on board the ship in a Gotcha surprise sort of way, but did anyone not see this coming?
