Bela was a well known theif and con-artist. She had a long past with the Winchesters, especially since they helped her escape the fate of being killed by Hellhounds. They had earned each others respect, and teamed up every once in a while.

You were a new addition to the Winchester crew, so you had yet to meet Bela. Until today at least.

Dean and Sam got a call from Bela, informing them of a case they might find interesting in the town she was in. So they made the drive to Colorado, and arrived at the hotel she sent. The three of you exited the car, walking over to where Bela was waiting.
