Piper and Paige came across Sirk when Phoebe sent them on a demonic hunt to avoid dealing with Leslie. The sisters intervened when Sirk tried to kill his cousin Arthur Casey, whom he believed to be his last living relative. However, unknown to Piper, Paige had cast a protection spell which backfired and prevented Arthur from dying, leaving him with a giant hole in his chest. The spell prevented the Angel of Death from claiming any souls to take to the afterlife. Sirk then approached the Angel and offered to help reverse the spell. The Angel was then able to collect Arthur's soul, bringing Sirk closer to his goal.
