The department store, Carlos admits, isn't ideal. It's too big, too hard to secure. But he had nearly been caught out in the open -- he had been searching the stairwells, looking for people he knew, and before he knew it, he realized he only had a minute or two before the gates were due to close.

He had darted inside just in time to have the gate slam shut behind him.

Bruce will most likely see Carlos before Carlos sees him: a man in a lab coat, with a paintball gun strapped to his back, walking from section to section, clearly trying not to be seen. He's trying to find a place to settle for the night, a place he's not likely to be disturbed.
