the girls are stucked in the underworld phoebe piage and christy are dead. its left for the two remaining witches billie and piper to save their sisters.
they both end up summoning the hollow at the same time which spells for disaster. this episode was well written and plotted a good foundation for the finale for once the sisters are faced with real fights not only against evil but their own lives.
i hope billie sees that christy isnt who she claims she is and that the sisters really care for her with the sole aim of fighting evil.
simply expolsive. loved it cant wait to see how they survive from this
