Hades, god of the underworld speaking. Oh hi Sephi! What can I help you with today? Ohoho, you killed them all?! How positively diabolical, I LOVE IT! Ah, yes, I can see how the rewind spring can be a thorn in your side in that case. Of course babe, I'll make sure no one gets close to it anymore. Anything for my fellow villains. All right. Love you. Ta-tah.

Oh hello! Sorry, due to evil scheme-related reasons, the rewind spring is closed until further notice. Now get outta here before I smite you.
