Stone of the Oversight

Willow uses this kind of diamond as well as the bramble Lethe to make forget to Buffy and Tara their marigolds and them allow to be happy again. To do it, made Willow burn a branch of bramble Lethe in the chimney, then recites a formula while burning the transparent stone which, until the fate(spell) acts, will darken until shine with green color. But any dérappe when the bag of bramble Lethe catches fire and multiplies tenfold the power of the spell which affects all the band and produces everybody amnésiac. Finally, it is Xander who, accidentally(by chance), crushes the magic crystal fallen from the pocket of Willow and breaks the spell of oversight(forgetting) and everybody finds the memory.
