I was sad to see Troy go, too, but you have to agree with Trump about him being a loose cannon and not quite responsible enough to run a multi-billion-dollar company. He comes up with crazy schemes, and sometimes they work, but they often do not.
In that way, I can see how Trump would pick Kwame over Troy, because although Kwame is not a strong leader (and for that reason, he won't win), he is smart enough to think things through before he does them, and he is smart enough to rely on the skills and talents of his teammates/advisors.
I worry because I think Trump really likes both Amy and Nick, but I don't think either of them should win. They're both too slimy and manipulative, and although I think they would be good at running the company at first, after awhile people would start to see through them and lose respect for them.
Personally, I think Bill is the best candidate for the job. Like Kwame, he recognizes when he should step back and let others come up with ideas, but he also has quite a few of his own. Unlike Troy, who comes up with an idea and runs with it without thinking it through, Bill comes up with an idea and considers its feasiblity before implementing it. And, unlike Amy and Nick, Bill has very strong ethics and will not screw over clients or coworkers just to get ahead—he knows that he can rely on his own skills to prove his worth instead of putting others down to make himself look better. (Plus, he's super-cute! eeeeeee! [I just had to throw that in.
