While Hawkeye was busy convincing the cops on the scene, Cindy spun a web to a nearby building, swung neatly over the police line, then landed rather anticlimactically by the bank doors. A few of the police officers had turned their heads and one of them was already shouting at her that she needed to go away and leave this to the professionals.
She gave a sheepish wave as if to say, 'It's okay, I have this covered!' but the cops didn't seem convinced. She took a deep breath, steeled herself and edged closer to the door. She cracked it open slightly and tried to see what was going on. Her silk-sense was flying high but it didn't seem to have gotten worse since she got on the scene so the bad guys probably hadn't noticed her yet.
It was better to scope things out before barging in, right? Maybe she even had time to come up with a plan.
