The Coin doesn't kill its victims the same way that it did in the previous episode. In that episode, the mystical blast causes their entire body to glow, as is shown in the flashback to Micki's death. In this episode it only caused their forehead to glow. When the Coin kills Vince, the effect is properly shown.
In the previous episode, "Tails", the Coin didn't bring back either of the dead men as near-mindless zombies as it does here.
Jack and Goreman both talk like there's only one cemetery in the city. They both refer to it as "the cemetery". Big cities, like the one Curious Goods are in, have more than one cemetery. For some reason Briggs goes to the same cemetery that Jack and Micki go to, but they'd have no idea that he would be going there.
