Sheila and Joel have done the thing that criminals always do, and they really need to learn not to do, if they’re going to become serial killers: returned to the scene of the crime. They’re still having the “did she or didn’t she” debate about Loki. When you’re married, some disagreements are just never-ending.
Sheila thinks she didn’t accidentally bite Loki, because she didn’t get that satisfying tingle that she gets when she draws blood for a kill. In her vagina. Joel tries not to be disturbed by his wife’s new murder kink, but the compromises that he’s making for the marriage are adding up quickly. Even with frequent, adventurous sex, he’s having trouble keeping up with the rapid fire changes and new demands. He blames himself for letting Loki escape. Sheila reassures Joel that she loves him for who he is, not who he thinks he should be. And Loki has clearly skipped town.
