The crowd, from through the door.
Actually, it occurs to me that I'm making an assumption: I can't see or blindsense people from through the door, but I can mindsight them. Does mindsight and read thoughts combine to let me ID specific people despite not having LoS on them?
If it helps any, I'm generally looking for a couple things: Anyone especially hostile (in a specific sense, not merely part of the mob), and anyone of relative ability or power who might have a low will score.
I"m hoping that mindsight and read thoughts should help get that info.
