Susan had known Tony Stark for a number of years now and never once, not once had she seen him so inibriated and out of control of himself. It shocked, but also scared her more than anything else. Thank god Steve was there to stop the whole thing before her friend had stripped down to his underwear. She could only image what Pepper and Happy were feeling right now or anyone, really, who knew Tony and knew this was not him. Yes, Tony liked to have a good time and yes, he liked to party, but he always had some sense of control. At that moment, before the entire crowd of possible peers, he had no control. He was drunk as a skunk as her mother used to say and the only thing that saved him was his friend, but the damage was only stifled and not gone.
Around her, the crowd mumbled and murmured concerning their host's actions, and she saw many of them press towards the stage, as if the empty place held answers or some remainder of sanity lost when Tony took the stage. The blond moved to follow after Cap, but was stopped by the sound of Cassie's voice and then she remembered the girl was his assistant to his assistant. Obviously, she was trying to curb the chaos and requested Susan's aid to do so. Her blue eyes strayed to the stage again and the abandoned microphone before she swallowed and turned back to Cassie.
Sue never, ever chose to use her powers unless there was a good reason and right now, it was protecting her friends from further shame or worse. "Yes, I can", she confirmed, "Come here". The lone member of the Fantastic Four wrapped a slender arm around the girl's shoulder to pull her close and then raised a hand. Instantly, there was field in front of them, caging them from the others in the room and allowing easy maneuverability to the stage where Sue stifled the shield and released her younger charge.
