Tread Perilously wraps up Halloween month with its annual visit to Supernatural. This year's episode: " It's the Great Pumpkin, Sam Winchester."

When a loving family man is killed via mysterious razor blades hidden in a piece of candy, Sam and Dean follow up and discover a witch's hex bag as the root cause. Suspects immediately become apparent via the family babysitter and her skeevy art teacher. But when Castiel (finally) and Uriel (Robert Wisdom!) arrive, it becomes clear the Halloween hex is related to the seals and the angels' mission from Heaven. Will they eradicate the town to stop Samhain from rising or is there more to their orders?

Erik is happy to see Castiel appear in an episode. Justin outlines his problems with later seasons of Supernatural. The pair also finally confront the show's myth-arc and debate the pronunciation of "Samhain." History Corner crosses the Rubicon and Andor gets a mention or two. The team also discusses Halloween Ends and any number of other horror movies. They also attempt to work out if Damien Thorn would've had a different life with another name. Justin tries to find more roles for Robert Sheehan. The connection between Mexicans and the Irish is reaffirmed and a surprise comic book writer discussion breaks out.
