Sarena Alexander had a lot of practice in sneaking. Hell, Remy had made it part of his goals in life, it was a short list, to make her as good as anyone else that he had ever come across. Not as good as him since then he'd have to battle for his position, but nearly. So of course he had taught her all the little tricks and signs for when someone was trying too hard. Granted, that was something that anyone who lived a mildly paranoid lifestyle would pick up. The people who looked like they were trying to be sneaky were usually amateurs who were up to something. The way that Molly was moving around said quite clearly that she was indeed an amateur up to something. All that looking around. Anyone with good sense knew that the easiest way to sneak anywhere was to behave as if you belonged and had a reason. Though having a pre-prepared reason tended to be a good idea too, just in case one did get stopped.
Well, naturally curious as to what the little bruiser girl could be up to, Ren followed along, but made much less of a show of it. There were so uses to being taught how to walk without making a sound. Then there were things like already knowing the layout and being able to figure out where a person is heading. There wasn't much on the lower levels that anybody would be interested in other than the medlab unless Molly was going to see one of the downstairs residents or the pool. So that narrowed down the choices a lot.
This was at least partially her fault given that she was the one who had followed Molly up in her thoughts about Dr. Reyes being a possible vampire and thinking on it, Ren had seen the woman during the day when the whole Legacy thing was going on, so it was probably all just overactive imagination anyway. Oh well, it beat homework.
