Distraction

Spider-Man flew through the air and slammed into the outer wall of the military base - having slingshot himself with webbing to look as though he was thrown. Instantly the guards raised their guns as one of them pressed a button in the gate house. Spider-Man picked himself up and wiped the dirt off his suit.

"Don't worry, I got this." He reassured the guards as more arrived at the gate, guns up. He then widened his eyes as he sensed a grenade rolling towards him. A grenade that Cat had rolled from out of site. He leapt to the left as he fired webbing to push the guards away. The grenade hit the gate.

Bang!

It went off, blowing the gate off it's hinges. Alarms in the military base went off as more guards came to the gate. Black Cat snuck off, while Spider-Man kept up the ruse. He leapt back to his feet and pretended to fight an invisible enemy, faking being knocked to the floor on several occasions. The ever increasing number of guards kept their guns at the ready, but didn't know where to shoot, so they just formed a wall where the gate used to be.

Cat snuck away into a quiet alley and pulled out her phone. She quickly wrote a message for Sierra:

You have maybe an hour or two.

She sent it. She had to keep it vague in case Sierra's phone is used as evidence upon her inevitable arrest. She put her phone back into her suit and swung to a vantage point to watch Spider-Man's fake fight, making sure to stay out of sight.

She waited until an appropriate amount of time had passed, for her to have broken in, gotten some evidence and escape. She then snuck back down to the place she was earlier and threw another grenade she had stollen from the construction site earlier. Spider-Man leapt away as the grenade came to rest under the front of an armoured truck.

Bang!

It exploded, lifting the truck into the air and dropping it on its die. Spider-Man swung away, using the explosion as cover, as met back up with Cat on a rooftop.

"So, what did you find?" He asked.
