Mirror, Mirror - Season 1 Episode 13

With the help of Ani, Louisa is able to follow Sir Ivor and Campbell to the train station. The girls hoping to be able to make the split second alignment they need. At the other end Tama is waiting to catch the train in 1919 with Jo and the train is running late. The alignment works and Jo is sent through to 1919 to a very surprised Louisa, but Sir Ivor is aware they are there thanks to Campbell. The drum goes overboard and the girls jump off the train. Campbell pursues but is unable to catch either of them.
