While Dr Todd has rapidly become one of Emmerdale's most talked-about newcomers, the actress behind her may already be familiar to soap fans. Caitlin is portrayed by Caroline Harker, who first appeared in the ITV soap in early 2025 before returning on a more permanent basis from February 2026 onwards.

Acting runs firmly in Caroline's family. Hailing from London, she's the daughter of actress Polly Adams and actor Richard Owens, while her sister is acclaimed actress Susannah Harker. After studying at the Central School of Speech and Drama in North London, Caroline launched her TV career in the early 1990s, first appearing in Casualty, Chancer and Growing Rich.

From there, she steadily built an extensive reputation on the small screen across some of Britain's biggest dramas and detective series. Viewers may have spotted her in shows including Middlemarch, Midsomer Murders, A Touch of Frost and Doctors. She also appeared as Wendy in the series Keeping Mum.

Her film credits extend beyond TV favourites, too, with appearances in The Madness of King George, Lady Godiva: Back in the Saddle and Mothering Sunday. 

I have to say so far right now, Caitlin Todd is a master manipulative character af the moment.

Caroline Harker is playing it brilliantly as a evil 😈. She is really pulling the wool of Jacob, Charity & Vanessa's eyes 👀.
