He may or he may not be idk, but on the off chance he is town one of those four are likely scum shines a light of suspicions and doubt on them
And if he's not town one of those four can share what they learned and if they suddenly die it'll only serve to reinforce the idea he's scum
I can garner more information sharing what I learned than I would keeping it to myself
Basically just condensed today's POE into 5 possible suspects
Why are you against me sharing what I learned to the class?
