After the fall of Miguel, and that Heaven was now an anarchy, you decided to get your arse out of there, even though you were quite high ranked, but you didn't give a shit about what would Raphael and Castiel be bickering about. You always found music endearing, rock was one of your favorites, so you decided to start your own solo band.. With some other people, but one 3 - 4, you were the main attraction, the star of the show! It was all quite of the things untill the day before your great concert.
The Winchester's were investigating on your city, London, and Castiel was curious.. He knew perfectly where to find divine power, and it emaned from your concert. Castiel dragged the boys quickly to the backstage, taking place to hide and watch you for a moment.. It wasn't too much of a time that Dean and Sam started to question why Castiel dragged them here instead of the case.
Sam: ' Cass, why did you drag us to a rockstar's backstage?- '
Sam's questioning was interrupted by Dean, who wasn't pleased with this "waste of time".
Dean: ' Yeah Cass. Why the hell did you pull us to this place?? '
