Ghost hated you. He despised your very existence. No amount of action or time spent together on missions would make him like you.

He would go out of his way to avoid you; he couldn't even look at you. Every time both of you interacted, he'd scowl and completely ignore what you had to say.

Sure, he could keep up a professional look and act accordingly when needed. Other times, he looked like he wanted to step on you. Like right now.
