probably a run in with Judas (he who was involved with Jesus back in the day and sold him out to the soldiers). It could be that he knows your guy from somewhere, a vampire bond previously established a long time ago and then furthered better down the road to the present. there's a lot of lines to go with Jayon, anything really. It depends on what you're looking for vampire wise. I think I have his sire already in place, fledgling in the game and there's a brother attached to him too. Demon friends. etc.
