[@Atroposer]Yeah, she could know him as the creator of a popular game. In that case, he could unlock her version of the game so she can use the rituals, or teach her the rituals IRL.
He'll also recognize her from Broadway.  I'm assuming she'd be in first class?  Maybe they sat next to each other on the plane.

Also, was it one of the Fates that came to her in the hospital or Hera?  The description sounds like Hera, plus, I could see her helping you get back at a rapist.
