"Watch your step."

The dilapidated building was a hazard on bricks, but they moved through it silently. Morgan and Emily led the way before they stopped and allowed JJ and Reid to catch up on Morgan's signal from their last position and repeated the process. There were two unsubs in here somewhere, they had been chased in and the only way out was through them. Cornering an unsub was like backing a wild animal into a corner, let alone two, made doubly dangerous by the fact that they were armed.

They came to a suspended walkway that looked shoddy at best, but they had to clear the whole building. Morgan nodded at Emily indicating he was taking point and he slowly advanced across the walkway, taking several wide steps to avoid holes in the grating. Emily cast a glance behind her, meeting JJ's hyper-alert gaze. "Watch your step." She whispered just loud enough for the blonde to hear her, only following after her partner when JJ gave her a firm nod.
