S03E08: 'A Very Supernatural Christmas'

It's Christmas time and Sam and Dean investigate a series of murders where the victims were pulled up through the chimney.

Sam realises they are dealing with a sort of Anti-Santa, a demon with roots in pagan lore.

Dean wants to celebrate Christmas the old-fashioned way as this is his last, but Sam refuses, not wanting to accept that Dean won't be around next year.

Sam flashes back to a certain Christmas when he waited for his father to come home to give him a special gift.
