Avery got a text from Regina saying she was good to go and grabbed the night guards two at a time, triple checking to make sure she got all of them out, before beginning to plant bombs in key places. She was going to blow this all sky high so it was a good thing the factory was in the literal middle of nowhere.
Angelo had studied blast radii and told her all about them when he first got into bomb-making. She knew how far away she needed to put those security guards so they wouldn't get hurt.
She also knew she was going to have to absolutely book it when she set up those timers so she could get to where they were before the bombs went off. This was the scary part.
As soon as the last one was set, she ran for her life and flinched when she heard the explosion go off. The helmet helped muffle the sound but barely. She untied the bewildered guards watching the smoking remains of the factory in the distance.
