S1·E8 Episode 8

As far as the Iredale's know, Joshua is dying from the effects of the toxic substance. Seeking help for Jo, Old Nicholas, the man who owned the shop, tells Royce that he has to go through the mirror. In the next yard, Sir Ivor hears Royce shouting his warning to Jo, who already knows what he had to say, but it creates a distraction to allow Nicholas to sneak back into the house. Louisa goes through into 1995, and Tama and her go to the library to see if they can find out whether or not her father survives. He does survive, but they discover that he dies in a train crash in 1928 because he didn't want to fly by aeroplane. Just as Louisa is about to go back through the mirror, Andrew walks in and demands to know what is going on.
