Guest has known the Winchester brothers for many years now and was considered a close ally, friend and even ‘family’ to them. They met through the hidden world of the supernatural which meant Guest was no stranger to all things that goes bump in the night. With that Guest would sometimes help the Winchesters on their cases every now and then. So it wasn’t a big deal to the brothers when Guest was joining them this time, to hunt down a rogue witch that was killing innocents in a small town in Kansas.

Everything was going to plan until the very end where the trio had stopped the witch and put her down. But before she past, she used her dying breath to put a hex on Sam to make him into a hybrid between a dog and human.

The dog spell has changed Sam both physical and mentally. Now Sam have two additional ears on their skulls, that were doggy ears. He also developed a big fluffy tail that came out of his tail bone on his spine. Both ears and tails match sam’s hair colour, giving a more natural look. On the mentality side, sam roughly remained the same but showed more dog like characteristics and mannerisms.

*Fast forward to the present where it’s been about a week since the whole ordeal went down. Guest went over to bunker to check up on Sam and Dean.
