Katrina and her husband, Ichabod, talk about what their children might be like someday.

The pleasant memory doesn't last however, as Henry's poison takes control turning Katina's dream into a terrible nightmare.

Soon Henry, a doctor and a couple of Hessian's barge into Abraham's cabin and test Katrina for the poison. The Jincan is doing its job.

Naturally, Abraham protests as this was not the arrangement but Henry tells the Horseman of Death that Moloch has a new purpose for Katrina.

Abraham struggles to keep his beloved at his side but Henry opens the shutters using the sunlight against the Headless Horseman.

During this distraction, Katrina manages to escape and makes her way to a nearby gas station.

One of Abbie's co-workers tells her that a woman in full Colonial garb was found and taken to the hospital. Ichabod and Abbie instantly realize the woman must be Katrina.

When they arrive, the doctor treating her tells them Katrina is suffering a serious infection. Thought Katrina attempted several healing spells this sickness is too strong and unlike anything she's ever seen.

While attempting to escape the hospital, Katrina spots the Hellfire club members Henry brought to the cabin. She and Ichabod escape but Abbie follows the villains to their lab. She steals a journal which hold the secret to what's ailing Katrina.

Ichabod and Abbie learn that Katrina is not ill, she's pregnant. They deduce their son, Henry, is behind all of this and appeal to his human side.

Henry laughs and confirms his mother is not only pregnant, but she's going to give birth to the Horrid King. That's right, Katrina is carrying Moloch himself.

Ichabod recalls that Benjamin Franklin had been researching the aurora borealis as a means to stop evil spirits. He does some digging and learns the phenomena will indeed stop Moloch from crossing over.

Franklin had designed a special prism that simulates the effect of the aurora borealis and hidden it in a tablet belonging to the Hellfire club.

Abbie and Ichabod return to the lab and manage to steal the tablet.

Meanwhile, Katrina is just moments away from bringing Moloch into the world. Ichabod uses the prism to stop the birth and banish the entity. However, not far away Henry collects Moloch's essence in a jar. Was this the plan all along?
