Protego Hufflepuff Calindu221
"This Spell cannot be used, instead acts as a barrier when a Prefect gives it to you. This Spell will trigger if you are the target of Friendly Fire."
Apparantly Mrpaper had Protego given to him by a Prefect. Calindu used Aguamenti on Mrpaper, cancelling the protego.
Mrpaper was after all, the target of friendly fire.My conclusion: they just wasted two spells...Okay, seems like I'm more confused then anyone else, just ignore me
