"Whatever happens, Don't interfere. No matter what."
That is what Seth had said to the group before they had arrived at the library and he began his confrontation with Seth. Those were the words echoing through Astra's mind as she watched those searing beams streak their way across the air separating the two men. Yet despite those words, she knew it wasn't right to just stand by and let Seth die.
Sure, he could make a knife and some other stuff float around, but that was nothing compared to the speed and raw power of Sirius. He might have been a scumbag, but there was a reason that he was kept around and that was his power.
However, when she began to raise her hand to interfere despite his wishes, she was beaten to the punch. Literally. With everyone so focused on their argument and the ensuing chaos, no one noticed the ghoulish minion slowly and casually making his way around the group until he was positioned right behind Sirius.
