My thought process was this:
We've tried asking the same question over and over again: "what's your affiliation." And Kitz wasn't really understanding. So I just asked it another way. If she could give out fruit as her night action, it would be her ability and thus, fruit vendor isn't her affiliation. If this whole affiliation/ability thing still hadn't gotten resolved, we could have reasonably assumed if fruit vendor is her ability depending on if someone got fruit N1. Unless someone besides Kitz also picked fruit vendor for ability.
Does that make sense or am I clear as mud?
