Alright, cards on the table:
My role is called a Contact Counter. The way it works is that I target someone, and I get a count for the number of people who are in their contact chain. My visit counts towards that chain. So, for example, if I used it on myself and no one targeted me, it's a chain of 1. If I used it on someone else who didn't visit anyone, it's a chain of 2. If my target does visit someone, it's a chain of 3. I got a whole list of possible results based on various interactions after asking several questions of Bullish, so if people want to know them, I can go through it.
The long and short of it: I used my night actions on Kohai NP1 and Vader NP2. I chose two players who claimed roles that did not visit, since picking a target who did visit someone else would just confirm that they had visited someone, not who they visited or why. Both Kohai and Vader had chains of two, meaning that, absent any fuckery, I confirmed that Kohai did not visit anyone NP1 and Vader did not visit anyone NP2.
