If one of the teachers accidently walk into Leighton bending PC over and fucking them while they're crying do you think any of them would help PC? or would they walk out when PC is just cryin n calling their names? would they react diferently if the PC is a delinquent? Oh god imagine the aftermath, PC can't trust any teachers anymore:(
I believe that all of the teachers would step in, regardless of personal feelings towards PC.
Doren, in particular, would be throwing punches without a second thought, as would River. Even if River can't stand a delinquent PC, they refuse to stand by and let a student be violated.
Sirris and Winter are more level-headed, shouting at Leighton and covering you with their jacket or whatever's available. If it were consensual, maybe Sirius could've overlooked it, but you're crying and shaking.
Mason straight-up freezes, they're not comfortable touching you or Leighton and, if possible, will shout for a fellow teacher to come and help.
