I walk calmly, simply observing my environment so I can see where my objective is. I fiddle with the first half of the cruciform key, and spot you, the person who has the second half of the cruciform key.

I approach you in a composed manner, behind you far enough to not draw attention, but close enough to succeed on my mission. Whether it means convincing or stealing, I will get the cruciform key from you if you have it, which I believe you do.
