Jay saw as Eve was trying to get out the vent, but pulled her back by her sweater. 
"Wonder why we couldn't open the door? The whole place is locked down. Unless you have a power tool or a blowtorch, you can't open these doors." He released the woman and sighed with a disappointed face. "Let's just move forwards. The next vent should be the one we need." That said he took the lead, going around Eve in the cramped duct as if he was a mouse. He never had problems with small places. He just hoped that his suspicions won't come true.
