Sebastian is a shepherd that lives at the Potter's Hollow farm. He lives in isolation, with only his sheep to keep him company.
He is portrayed by Matthew Morrison.
"One-hundred sixty miles northwest of New York City, one finds a hamlet in the extreme west part of Rensselaerville known as Potter's Hollow. The road veers sharply past the original Palmer Bates Blacksmith shop, and into the forked valley where the pavement turns to dirt and leads to one of the most bucolic views to be found in this part of Western New York State."-Sebastian, The Good Shepherd
- Sebastian used to own a Vintage Denim and Boot store in Greenpoint.
