Christine Everhart was the love interest of Tony Stark before Pepper Potts. Sort of. She's lower down on the list because she's not the biggest character, though she plays a big part in the Iron Man movies. If you're looking for a story on someone like Tony Stark, being a hot reporter will work to your advantage. He's way too horny and cocky not to give away information just to get some. Does that make him somewhat of a prostitute? Yes, absolutely. Rich people can do whatever they want. Just look at Donald Trump.
I wonder if there are fans out there saying, "I really hope Christine Everhart makes an appearance in 'Infinity War.' They're all made that there isn't a Christine Everhart action figure. Don't bother looking it up. I just did and couldn't find one.
