Tony & Darcy
If Tony had any doubts about the results of those DNA tests, Darcy probably just erased them.
She wondered how long he'd known, but that wasn't a conversation for now. There would be plenty of time to ask all of her questions later. At the moment, they should both get back to the party. A party she would definitely not forget, even if she didn't get lucky with a shapeshifting alien and his trunk full of sex toys.
"Enjoy the rest of the party," she said. Maybe now that he'd spilled his secret, he'd be able to relax and stop acting so weird. "I'll talk to you soon. Promise."
Darcy leaned in to kiss his cheek before exiting the coat closet. Hopefully no one had seen them go in there together and gotten the wrong idea.
