Sofia blinks, startled from her silent observations by her brother's words. "Of course," is all she manages to say, before Anton is disappearing into the crowd again. Another blink, and she's lost him. She takes Edeldhur by the upper arm and mutters in his ear, "Don't let him drink too much, and keep him out of trouble," before letting the elf go, and leaning against a nearby wall.
She doesn't find the event stifling like her brother does - she actually finds it rather interesting. She simply knows her presence isn't the best here, as diplomacy and reason were never her strong points. Slicing a man open three times before he hit the ground? That was. It was the reason she wore her old lamellar, and both her blades, even to such a formal event - she knew she could get away with it. She may not be able to talk fancy like her brother, but she could get people to back down if the situation arose.
