Okay, remember how they all had a panic attack because the spell almost didn't work in time and almost got attacked before they were ready? Why couldn't Willow have just done the spell like the night before and made the Potentials Slayers so they were ready before they went down? Cause as far as I knre, all she had to do was tap into the scythe...thatwouldn't have worked at home? LOL. Am I missing something?
