1. Vamp probably just didn't have anywhere to go after his squad died, and he probably has no problem working for the highest bidder. He doesn't seem to care much about his own life anyways. His involvement with Naomi may have contributed something to this, but all in all it just isn't clear.
2. It really isn't totally clear what Naomi's motives are. She may or may not have had some kind of romantic liason with Vamp. She may have just been doing it in order to get closer to Liquid's plan, but that would mean they probably were romantic. Once again it really isn't clear, and in this case I think Kojima kind of intended it to be that way as a lesson on moral ambiguity slightly similar to what he did with The Boss in MSG3.
3. I don't think Eva knew that it was Solidus, or else she wouldn't have felt such a personal attachment to the body. She probably wouldn't have been keeping it alive for any other purpose. She may or may not have known that his DNA allows you to connect up with the Patriot system as a passkey. Her going into the flames leads me to believe she thought it was Big Boss. But did they say in the end that it was her who helped reassemble Big Boss?
4. No, it wasn't explained (at least where I saw) where Sunny was or how Raiden rescued her. It wasn't totally clear who did all the work on his body either. What I want to know is how they put his arms back on! How the hell did he go back to being a normal, biological person after all that. I thought he replaced his blood with artificial blood. Once again, it isn't totally clear.
5. Raiden just seemed to not be able to handle going back to his regular life after all of the revelations about himself and the world which he came to during the MGS2 mission. Did he blank out his past about being a child soldier? If so, those memories resurfacing may have had a lot to do with it. He just couldn't accept a normal life after the events in MGS2, especially after he learned about The Patriots.
6. This honestly may have been a decision Kojima made later and just accomodated the story to account for, but he has been setting up Ocelot to be a strange double or triple agent since MGS1 (remember conversation after credits). Ocelot obviously was involved with the U.S. government, even as early as in MGS3, and it is definitely plausible that he was a member of The Patriots all along. After Liquid completely took over Ocelot, I think the way it works is that Liquid can tap into whatever Ocelot has physically or mentally, but Ocelot was pretty much entirely dormant. That way Liquid would have the info Ocelot had. I honestly think Liquid could have figured out a fair amount of it on his own though, especially with his knowledge about the importance of Big Boss's genetic code.
We had two bags of grass, seventy-five pellets of mescaline, five sheets of high-powered blotter acid, a salt shaker half full of cocaine, a whole galaxy of multi-colored uppers, downers, screamers, laughers…Also a quart of tequila, a quart of rum, a case of beer, a pint of raw ether and two dozen amyls. The only thing that really worried me was the ether. There is nothing in the world more helpless and irresponsible and depraved than a man in the depths of an ether binge. –Raoul Duke
It is hard to shed anything but crocodile tears over White House speechwriter Patrick Buchanan's tragic analysis of the Nixon debacle. "It's like Sisyphus," he said. "We rolled the rock all the way up the mountain...and it rolled right back down on us...." Neither Sisyphus nor the commander of the Light Brigade nor Pat Buchanan had the time or any real inclination to question what they were doing...a martyr, to the bitter end, to a "flawed" cause and a narrow, atavistic concept of conservative politics that has done more damage to itself and the country in less than six years than its liberal enemies could have done in two or three decades. -Hunter S. Thompson
