Ever After (S05E08)

Mrs. Tishell can’t keep her feelings for Martin a secret any longer and, under the influence of a mix of medications, makes a bold move. While she is looking after James Henry, she hops on a bus out of Portwenn, leaving a note for Dr. Ellingham instructing him to "meet them at the castle." This prompts Martin, Louisa, Ruth, and PC Penhale to embark on a frantic mission to track them down.
