Yeah it shouldn't really matter for this situation, since you were just looking for a location.
It's still technically the same thing as asking the three questions I just like it a little better this way is all. I'll explain with a quick example and if you have more questions I'll answer them.
Say River is sitting on a roof top watching Vincent from a distance and uses aura perception. The first round she spends looking at him she sees a pale red aura about him (pale means it's a kindred, red mean he's angry). If she continues to concentrate on it for another round she sees sparkles in the aura (sparkles indicate he's using thaumaturgy). A third round she sees that the aura is actually shifting from red to yellow (he's not only angry but also afraid of something).
Slight correction to the way I'll be doing the aura perception. I might mention the colors in the description but I'll just basically tell you what it means when you see it, so you won't have to try and figure out what I mean by say orange. So basically you would get the answer to the three questions like it's normally done as long as you concentrated on reading the aura for the three rounds, two rounds you get two questions, and so on. Make sense, kinda sorta?
Also Sinful it's this coming up Monday when you'll be gone for a few days right? Because if so I'll try my darndest to finish up with the current night this weekend, or at least your portion of it.
