Other mistake: When Prue astrals back to recite the spell to reverse the awakening spell, she and Phoebe don't actually complete the spell, they just recite the first paragraph "What was awakened for its sleep, must once again slumber deep" the rest according to the book of shadows is "return the disease to whence it came, so life can ease back to the same".
