When the car parked where Lena suspected was the back of the building she signaled for Clive and Romeo to stay inside the vehicle while she got out to head towards what she believed must've been the door. She didn't think that there was any reason to let Jovani know she was there, she figured that once she input the code that the security system would let him know that someone was getting ready to enter the building.
Even though there didn't seem to be anything to be worried about, that didn't stop her from touching where the breast pocket where her jacket was to make sure that her gun was still there. The fact that there was no one else around somehow also made her feel more on edge. She had expected that someone would've been assigned to meet her rather than for her to just invite herself inside.
