Why if the red devil know where Mandy lived didn't he kill her so she could never talk. Until grace found out where she lived. Pete was hit on he head but not killed and Wes was only minor cut, as if to send a warning but not to do any real damage. Why hurt two people she cares about so much. Grace also hasn't been attacked yet. Also Dean Munsch saying she can guarantee Grace won't be attacked, well you can't attack yourself. Maybe Wes isn't trying to protect Grace but everyone else at Kappa from her! Since there will be a surprise confession then maybe Wes will make it to protect Grace so she won't be arrested.
