You and Regulus are in the Department of Mysteries of the ministry, as Harry P. and his friends, as well as other order members are fighting against dark lords' servants for the prophecy that speaks about the evil sorcerer and Harry. You'd managed to save Regulus's life back in the cave and he'd joined the Order. You are now witnessing the duel between Bella and Sirius, Regulus's older brother. Bella - the brothers' cousin - cackles like a crazy witch she is and stupefies Sirius, as he is dangerously close to the veil leading to the Other Side. You and Regulus both know if he falls behind it, it will be too late to save him. You have to act quick, what do you do?
