Ash is busy sawing up his dad's body when his old man appears to him as a ghost. As in "It's a Wonderful Life", Brock shows his son an event from years earlier, in this case when a Knight of Sumeria, bearing missing pages from the Necronomicon, came looking for The Chosen One, but wound up locked in the cellar of the hardware store with only tins of Spam for food. Meanwhile, Kelly and Brandy are attacked by a deadite Pablo.
Season three seems to be heading for a mid-season slump, Episode 4 being a fairly dull effort that is packed full of clumsy exposition, but which rarely picks up pace - except for the bit where Ash is attacked by tentacles that emerge from the wall of the shop's cellar; however, that scene feels like it was added solely because the writers knew just how monotonous and talky this one was. It doesn't fool me. Give me blood, give me guts, give me twisted humour, and give me plot developments I can be invested in.
Gory highlight: Ruby pulls the branch from Dalton's chest resulting in a massive gush of blood. The Knight of Sumeria then pulls a gun and blows his own head off.
