Steve/Sabrina
After leaving Yelena, Steve went to find Sabrina again. She looked so young in a room filled with stuffy old people. He know how deceiving looks could be. Wanda had been young when they had met her, but she'd been extremely powerful even then. It seemed the same was true for Sabrina, but powers and maturity weren't the same thing.
He offered Sabrina his arm when he got close. "Why don't we take a walk?" It would seem perfectly natural that they'd circulate and got to know the nobility. After all, rich people were still seen as inferior if they didn't have the proper title, and he was fine with that part. He could play nouveau riche better than aristocrat and any faux pas would be dismissed as him not having the proper manners.
"So how are you enjoying the evening? Probably not what you usually do on a Friday night," he said with a smile.
