Parity cop interactions with roleblockers:

Pcop, Alice (town), Benedict (scum), and Charles (town) are in a game. Pcop checks Alice, Ben, Charles, in that order.

What if there are no RBs?
N1 Pcop checks Alice, no results yet
N2 Pcop checks Ben and gets DIFFERENT
N3 Pcop checks Charles and gets DIFFERENT

What if Pcop gets RBed N1?
N1 Pcop checks Alice and gets roleblocked
N2 Pcop checks Ben, no results yet
N3 Pcop checks Charles and gets DIFFERENT

What if Pcop gets RBed N2?
N1 Pcop checks Alice, no results yet
N2 Pcop checks Ben and gets roleblocked
N3 Pcop checks Charles and gets SAME, because it's comparing to his last check, which is on Alice.
