Siegfried decides to take on a new student for a bit of practical experience. Calum is none too pleased but the student is a close friend's only child and he won't hear any complaints. Calum is also in a bad mood when Deirdre has to leave earlier than planned but regrets her departure less when the student, Emma Styles, arrives. She accompanies him on his rounds and he is quite taken with her but he questions whether it's practical for a woman to be involved in heavy animal work. Jack Sanders dog doesn't seem to be recovering from a fairly minor cut.
