First: Is there any indication inside the lab that security might be coming at any time? Video cameras, someone calling, etc?

Second: Is there any other avenue of escape other than the door(s) she used to get in?

Third: Are there any computers/desks used for office/paperwork/labwork? I assume they're locked and password protected but would common IT admin override passwords work to unlock it?

Fourth: Are there any blood samples, and if so, are they labeled? If they are labeled, is Steve's blood present? If it is, she's taking it.
