During the Halloween spell during Season 2, Spike and Buffy discover that Buffy Summers is the reincarnation of Lizzie Addams, the younger stepsister of Cecily Underwood, the woman who rejected William and sent him into the arms of Drusilla.

Giles tells Buffy she can't get pregnant, but later she finds out it takes a special type of mate. Will she and her mate be able to overcome all the outside influences trying to keep them apart? Loosely based on a challenge at BSV and has rewritten canon with Spike not coming to town with Dru in Season 2.
