Eh. Like the CEOs of companies know anymore than anyone else working for the company, if anything, they know substantially less. Last I remember, Philip really has no place running a business anymore than Melanie. Let's face it, this is all silly, but I suppose we are supposed to suspend our disbelief. Sure Melanie is in over her head, it is childish of her to use this thing to try to get a guy's attention, but it is up to Philip with whether or not that works out.
I can't blame John for not accepting the shipping terms, afterall, he couldn't even remember his own name. Philip paid Paul to plant massive amounts of illegal drugs on John's ships, much to Victor's dismay. Philip has a habit of acting like he is running the mob instead of running a respectable company. And if the spoilers are any indication, Philip should know better than trying to manipulate Melanie by kissing her to try and get what he wants. How must that make Stephanie feel? I believe Philip will stop at nothing, and I think just as much as Melanie is in over her head, so is Philip.
I personally do not believe Melanie was manipulating Nick, Nick is ill and did what he wanted and what he thought was right in his sick mind. Yes Melanie is guilty on taking Nick up on his hospitality, but Melanie has done just as much for Nick as he has done for her. Melanie had courage to go to court and testify on Nick's behalf after everything he did to her. I wouldn't do it, and I don't think many of us would. Giving her the project was the least Nick could do, he tortured Melanie for the longest time, making her believe she was a murderer so that he could lock her away and keep her for himself. Considering what Melanie has been through, if people can manage to find sympathy for Nicole, I really do not see why no one can find sympathy for Melanie.
