You've worked for him for over a decade. That doesn't make worrying about him any easier. You've been through plenty, but you don't blame him for any of it. Sure, you were only involved in most of it because you're involved in his life, but you wouldn't have it any other way. All this time, and you can't help but have feelings for him. It's hard, caring about a man like him. You wonder, not for the first time, how Mrs Stark managed to reel Mr Stark in from his womanizing ways.
That of course, makes you remember something the Captain said to you. You hope that you can be like her for your Mr Stark.
