Carol, Clint, Nat, and OPEN - Arriving at scene
Natasha had been tense during the flight from SHIELD to the scene, but she'd remained more or less silent, only responding to Clint when he'd asked a direct question. She had initially checked briefly on the X-Men, then followed her teammate to lend assist to Carol. As the blonde directed non-essentials towards the exits and worked on crowd control, she let Clint head her way while she herself slipped into the crowd to take a more personal approach. She wasn't in uniform, and to the average person she was simply another helpful civilian, even if she generally, like Clint, moved against the crowd. An elderly woman here, a child separated from his parents there - she did what she could to keep things orderly while at the same time checking those she could for weapons, and studying faces so she'd remember them later, if needed.
After a few minutes, Nat moved towards Clint and Carol, hoping to touch bases and find out if either had yet discovered anything - but something told Natalia that the culprit was likely long since gone.
