Scream for me, Ireland!

At the end of The Dark Path, Jamie helpfully observed that the TARDIS was landing in the sea. Well, perhaps it was just a loch because we're not quite ready for the Fury.

Here in "Screamager", it is 14th century Ireland and he and the Doctor are off investigating some threat or other - Victoria guesses it has to do with robots - leaving their companion with a welcoming family comprised of Cormac, his wife and son, Sorcha and Tadhg, and his brother, Niall. (I presume "screamager" means someone who screams or has screams[?] just like a dowager has a dower.) One night she sees a horrific face outside of her window. It looks to be of an old woman and is deathly pale. Soon after, the household servant, Martha, is found dead and Tadhg has taken ill.

Each night Victoria sees that hideous face and screams. And a new member of the family comes down with a fever.

The Doctor and Jamie return from their venture and our Time Lord hero diagnoses the fever as The Black Death. The TARDIS crew stay awake that night and confront the creature that has caused Victoria to exercise her lungs so. It turns out to be a banshee, the spirit of Irish lore whose shrieks herald the death of a family member. It turns out business is good, too good, perhaps, with the Plague running wild and it has come to recruit Victoria and her pipes which have had a lot of practice at screaming.

The Doctor, of course, steps in and does some homebrew medicine to save Niall which deters the banshee.

All too often Victoria is an archetypal damsel in distress who can do little but scream. In her defense she says here, "Wherever we go, there’s always death. Always. And I can’t help screaming, really I can’t." And to Rayner's credit, she takes this habit and makes a story of it, gives her screams some importance beyond being a signal to draw the attention of more capable figures and a way to end an episode on a cliffhanger. They're integral to this story.

It is here that Victoria decides her fate. Her time with the Doctor and Jamie is near an end. "I don’t know if I want to do this any more," she says.
