   Summary

   After creating a theory that could allow you to not only dress similar to the brothers in their demon forms, but also wield their magic, Lucifer makes the decision to help with making this theory come to reality!

   And of course, this leads to something more between the two of you forming!

   But will this theory fall apart? And further more, how far will beings go to make it theirs?
