I remember part of the fic where Xander takes Spike to a junk yard and the demon owner helps zap the chip with a big magnet, and then Xander arranges for Spike to get a car, which is magicked.
And at another point Spike talks to these time walking demons and goes back in time to kill Xander's Dad so no one will know he did it.
Someone help please? Thank you:)
