   Summary

   After being used as a battery in Vox's "Might of Lilith" machine, Lucifer wakes up sick, weak, and experiencing changes to his body he can't explain.

   When Alastor volunteers to monitor his recovery, neither of them realizes that a moment of unconscious contact during their rescue has resulted in an impossible consequence.
