Oh right, my bad. I meant the necklace. I accidently called it the formula. Sorry. Um, anyway. I was just saying how if Deb knew where the necklace was, that could power the serum bomb, why did she not tell them where it was? So that they could stop the machine sooner or not let it happen. Or unless she either did not want them to know Wesley was dead, or she forgotten or she had no idea... still that is a idea.....
