(( I just noticed your first post mentioned turrets. They were destroyed a while back. ))

Sarah gave the man a look, then figured the best route around the mansion that would hide the mafia-esque sections while maintaining the fascade of Kindersley Computers. Well how was she to know this guy already knew of the mansion's real purpose?
"Yeah, of course."

She first gestured to the room they were in now, pointing out the various expensive appliances. "Common room, employees mostly come here to relax. Has a bunch of posh electrical stuff, very expensive."

She then pointed through to the dining room giving relevant commentary.
Next she lead him to the entrance hall, giving a shrug as she explained she didn't know where the music was played from. She did though, suspect it to be from either Tika's room, or his computer.
The games room was next, where Sarah pointed out the various activities.

"And upstairs are all the employee rooms, if they want to stay overnight. Right now they're all out, ah.. At some computer conference."
